Leaching is the
Detalhes da Resposta
Leaching is the washing down of soil nutrients, minerals, and other soluble components through the soil profile by the downward movement of water. When water moves through the soil, it dissolves and carries away soluble components such as nutrients, organic matter, and minerals, which are then transported to deeper layers of the soil or to groundwater. Leaching can be both natural and anthropogenic. Natural leaching occurs due to rainfall and other natural processes, while anthropogenic leaching can occur due to human activities such as irrigation, agriculture, and the use of fertilizers and pesticides. Leaching can have both positive and negative effects on soil health. It can help to remove excess salts and other harmful substances from the soil, making it more fertile and suitable for plant growth. However, excessive leaching can also result in the loss of valuable nutrients and minerals from the soil, leading to reduced soil fertility and productivity. In summary, leaching is the process by which soluble components in soil are dissolved and carried away by water, which can have both positive and negative effects on soil health.

The contour interval on the map is
Detalhes da Resposta
The contour interval on a map represents the difference in elevation between two adjacent contour lines. Contour lines are used to represent the shape and relief of the land on a map. They connect points of equal elevation above a reference datum, such as mean sea level. The contour interval is the vertical distance between contour lines and is usually indicated in the map legend. A contour interval of 50 meters means that each contour line on the map represents an elevation that is 50 meters higher or lower than the adjacent line. Similarly, a contour interval of 100 meters means that each contour line represents an elevation that is 100 meters higher or lower than the adjacent line, and so on. Therefore, the correct answer to the question depends on the specific map being referred to. It could be any of the options given, or a different value altogether.

Detalhes da Resposta
The planet with the shortest orbit around the sun is Mercury. Orbit is the path taken by a planet around the sun. The time it takes for a planet to complete one orbit around the sun is called its orbital period. Mercury is the closest planet to the sun and also the smallest planet in the solar system. Due to its close proximity to the sun, it orbits the sun at a very high speed and takes only about 88 Earth days to complete one orbit. This makes it the planet with the shortest orbital period around the sun. In summary, Mercury is the planet with the shortest orbit around the sun because it takes only 88 Earth days to complete one orbit due to its close proximity to the sun.
Pergunta 9 Relatório
Spits are formed by
Detalhes da Resposta
Spits are narrow, elongated landforms that extend from the shoreline out into the water. They are formed by the action of waves, specifically longshore drift and wave deposition. Longshore drift is the movement of sand and other sediment along the shoreline caused by the angle of wave approach, while wave deposition is the process by which sediment is dropped off and deposited by waves as they slow down and lose energy. As waves approach the shoreline at an angle, they cause sediment to move along the shore. When the shoreline takes a bend, the waves slow down and deposit the sediment they are carrying, forming a spit. The direction of the spit is determined by the dominant direction of the waves and longshore drift. Over time, spits can grow longer and wider as more sediment is deposited by waves. Spits often have a curved or hooked shape at the end, which is caused by the change in direction of the waves as they reach the end of the spit.

Detalhes da Resposta
The ozone layer is found in the stratosphere. The atmosphere is divided into several layers based on their characteristics such as temperature, pressure, and composition. The stratosphere is the second layer of the atmosphere, located above the troposphere and below the mesosphere. It contains a high concentration of ozone, a gas made up of three oxygen atoms (O3). The ozone layer is a region within the stratosphere where ozone is concentrated. It plays a critical role in protecting life on Earth by absorbing harmful ultraviolet (UV) radiation from the sun, which can cause skin cancer, cataracts, and other health problems. In summary, the ozone layer is found in the stratosphere, which is the second layer of the atmosphere located above the troposphere. The ozone layer is important in protecting life on Earth by absorbing harmful UV radiation from the sun.

Detalhes da Resposta
There is no planet that revolves around the Sun in a clockwise direction. All planets in our solar system revolve around the Sun in a counterclockwise direction when viewed from above the Earth's North Pole. This is known as prograde motion. Uranus is the only planet that rotates on its side, which means that its north and south poles are almost where its equator is, and it appears to be spinning clockwise. However, when viewed from above the solar system, Uranus still orbits the Sun in a counterclockwise direction, just like all the other planets. Therefore, the answer to the question is none of the above.

Detalhes da Resposta
The high temperature in the interior of the earth leads to the formation of a type of geothermal feature known as a geyser. A geyser is a vent in the Earth's surface that periodically ejects hot water and steam. The heat from the interior of the earth causes groundwater to boil, resulting in the explosive release of steam and hot water. The water erupts with great force, shooting up into the air in a spectacular display. Therefore, the answer to the question is C) Geyser.
Pergunta 19 Relatório
The most satisfactory explanation for the formation of fold mountain is
Detalhes da Resposta
Fold mountains are formed as a result of compressional forces, which occur when two tectonic plates converge and push against each other. These forces cause the layers of rock to bend and buckle, forming folds in the Earth's crust. Over time, these folds can become more pronounced and eventually form mountains. The compression forces are caused by the movement of tectonic plates, which are massive slabs of rock that make up the Earth's crust. When two plates collide, one plate may be forced underneath the other, or they may both crumple and fold upwards, forming a mountain range. This process is different from faulting, which occurs when there is a sudden movement or rupture along a fault line, resulting in an earthquake. Vulcanicity is also different, as it refers to the movement of magma and volcanic activity, which can create new landforms but do not typically form fold mountains. Tensional forces, on the other hand, occur when tectonic plates are pulling away from each other, creating features such as rift valleys or mid-ocean ridges. Overall, the most satisfactory explanation for the formation of fold mountains is compressional forces caused by the convergence of tectonic plates.

When the roof of a natural arch collapses, the resulting rock pillar left standing in the sea is called_____?
Detalhes da Resposta
When the roof of a natural arch collapses due to the continuous erosion of the sea waves, the remaining rock pillar left standing in the sea is called a "stack". A stack is a geological landform that is formed as a result of erosion caused by the sea waves on the coast. These waves erode the softer rocks and cause the collapse of the roof of a natural arch, leaving a tall, vertical rock pillar that stands out from the sea. Over time, these stacks may also erode and eventually collapse, leaving behind a stump or a rocky platform.

Detalhes da Resposta
The summer solstice is the day with the longest period of daylight and the shortest night of the year. It occurs when the tilt of the Earth's axis is most inclined towards the sun. In the southern hemisphere, the summer solstice falls on December 22nd. This is because the Earth's axis is tilted away from the sun during the winter months in the southern hemisphere and towards the sun during the summer months. The summer solstice marks the point when the southern hemisphere is tilted closest to the sun and experiences the longest day of the year. Therefore, the summer solstice falls on December 22nd in the southern hemisphere, not on March 21st, September 23rd, or June 23rd.

Pergunta 35 Relatório
Which of the following climatic belts has the highest durnal temperature range?
Detalhes da Resposta
The diurnal temperature range refers to the difference between the maximum and minimum temperature in a day. The climatic belt with the highest diurnal temperature range is the desert. Deserts are characterized by hot and dry weather conditions during the day and cold temperatures at night. This means that the diurnal temperature range in deserts is usually very high. During the day, the temperature in a desert can be very high, sometimes reaching up to 40-50°C, while at night it can drop to below freezing point. This large difference between the maximum and minimum temperatures makes the desert the climatic belt with the highest diurnal temperature range. In summary, the desert is the climatic belt with the highest diurnal temperature range, due to its hot and dry daytime temperatures and cold nighttime temperatures.

Detalhes da Resposta
The cooling and solidification of magma within the Earth's crust results in the formation of a variety of geological features, including igneous rocks, volcanoes, and various types of landforms. When magma cools and solidifies underground, it can form a laccolith. A laccolith is a type of igneous intrusion that forms when magma is injected into overlying rock layers and then cools and solidifies, creating a dome-shaped structure with a flat bottom. Over time, erosion may remove the overlying rock, exposing the laccolith at the surface. Cinda cone, composite cone, and lava plateau are all landforms created by volcanic activity and not by the cooling and solidification of magma within the Earth's crust.

Detalhes da Resposta
The tilting of tree trunks, poles, and piling of soil behind a wall are effects of soil creep. Soil creep is a slow and gradual movement of soil down a slope under the influence of gravity. It happens when soil particles are loosened by rain, freeze-thaw cycles, or other factors, and then they move slowly downhill due to gravity. The movement is often imperceptible, but it can cause visible effects like the tilting of tree trunks and poles, and the piling of soil behind a wall. Mud flow, rock slide, and landslide, on the other hand, are rapid movements of soil or rocks down a slope, and they usually happen as a result of a sudden disturbance like heavy rainfall or earthquake.

Pergunta 50 Relatório
Which of the following features is produced as a result of river capture?
Detalhes da Resposta
The feature produced as a result of river capture is a wind gap. River capture, also known as river piracy, is a geomorphological phenomenon that occurs when one river captures the drainage of another river. This can happen when two rivers are flowing in opposite directions, but one river erodes its channel faster than the other, and eventually captures the other river's drainage. When this happens, the abandoned channel of the captured river, known as a wind gap, is left hanging above the level of the new river channel. Wind gaps are characterized by a narrow, steep-sided valley that has no river flowing through it, and can be seen as notches or depressions on the ridges between adjacent valleys. In summary, a wind gap is the feature produced as a result of river capture, which occurs when one river captures the drainage of another river. Wind gaps are abandoned channels of captured rivers that have a narrow, steep-sided valley with no river flowing through it.
