Detalhes da Resposta

The most suitable statistical diagram to show spatial distribution of production is a dot map. A dot map is a type of map that uses dots to represent the quantity or density of a particular feature across a geographic area. In the case of production data, each dot can represent a certain amount of production, and the density of the dots can show areas with high or low production levels. This allows for a clear visual representation of where production is concentrated and where it is less prominent. Pie charts, divided circles, and line graphs are not suitable for showing spatial distribution of production. A pie chart is used to show proportions of a whole, while a divided circle is similar to a pie chart but is divided into more than one category. These charts are best suited for displaying data where the whole is made up of distinct categories, rather than for geographic data. A line graph, on the other hand, is used to show trends over time, and is not well-suited for displaying spatial data.

Detalhes da Resposta

Temperature is the weather element that is controlled mainly by latitude. Latitude is a measurement of how far a place is from the equator, with the equator being at 0° latitude and the poles at 90° latitude. The closer a place is to the equator, the more direct sunlight it receives, and the warmer it tends to be. The further away from the equator a place is, the less direct sunlight it receives and the cooler it tends to be. This is why the tropics are warm and the poles are cold. So, in simple terms, latitude mainly affects temperature because it determines the amount of direct sunlight a place receives, which in turn affects its overall temperature.

Detalhes da Resposta

The best technique to prevent soil erosion in a humid, gently sloping area is contour ridging. Contour ridging involves creating ridges that run along the contour lines of the slope, which helps to slow down the flow of water across the surface of the soil. This technique helps to trap water, reduce its speed, and allow it to penetrate into the soil. By reducing the speed of water, contour ridging also helps to reduce the amount of soil that is carried away by the water, which reduces erosion. Terrace cultivation and intercropping can also be effective techniques for reducing erosion, but they are generally better suited to steeper slopes. Wind breakers can help to reduce erosion caused by wind, but they are not as effective for preventing erosion caused by water. In summary, contour ridging is the best technique for preventing soil erosion in a humid, gently sloping area because it helps to slow down the flow of water and reduce erosion, and it is well-suited to this type of terrain.

Detalhes da Resposta

A river that enters the sea at a gently inclined costal plain where tidal waves are weak will most likely develop into a delta. A delta is a landform that is formed when a river deposits sediment at its mouth where it meets the sea. The sediment builds up over time, creating a triangular-shaped area that extends into the sea. The gently inclined costal plain and weak tidal waves allow the sediment to accumulate and build up the delta over time. This process can lead to the creation of new land, making the delta a valuable area for agriculture and human settlement.

Detalhes da Resposta

The rock that is formed by wood subjected to pressure and heat is called "lignite". Lignite is a type of coal that is considered the lowest rank of coal due to its relatively low heat content and carbon content. Lignite is formed from partially decomposed plant material that has been subjected to increasing amounts of pressure and heat over time. As the plant material becomes buried and compressed, it eventually transforms into lignite through a process called coalification. Therefore, lignite is a sedimentary rock that is formed from the compressed and heated remains of plants, including wood. It is typically brownish-black in color and has a relatively low density compared to other types of coal.

Detalhes da Resposta

The best way to prevent a watershed from degradation is through forest reservation. Watersheds are areas of land that drain into a common body of water, such as a river or a lake. Forest reservation refers to the process of setting aside and protecting areas of forest from human activities that may cause harm to the ecosystem. Forests are important in watersheds because they help regulate water flow, filter pollutants, and provide habitat for wildlife. Fuel wood extraction and crop production can cause harm to watersheds if they are not managed sustainably. Fuel wood extraction can lead to deforestation, soil erosion, and loss of biodiversity, which can in turn impact water quality and quantity. Crop production can lead to the use of fertilizers and pesticides that can runoff into the water, causing pollution. Inter-basin transfer is the process of diverting water from one basin to another. While it can be a solution to water scarcity, it can also have negative impacts on watersheds, including altering natural water flow, disrupting ecosystems, and reducing water availability downstream. In summary, forest reservation is the best way to prevent watershed degradation as it helps to maintain the natural ecosystem functions that are important for water quality and quantity.

Detalhes da Resposta

The process by which organic matter is decomposed and synthesized to form part of the soil is known as humification. Humification is the process by which organic matter, such as dead plant material or animal waste, is broken down into simpler organic compounds by microorganisms in the soil. These simpler compounds are then combined and restructured into more complex organic molecules known as humus. Humus is a dark, organic material that is an essential component of healthy soil. It helps to retain water and nutrients, improves soil structure, and supports the growth of plants. Humification is an important part of the natural cycle of nutrient recycling in ecosystems, as it returns nutrients back to the soil for future plant growth.

An example of a landform produced by glaciation is

Detalhes da Resposta

A cirque is an example of a landform produced by glaciation. A cirque is a bowl-shaped depression on a mountainside with steep walls formed by glacial erosion. As a glacier moves down a mountain, it erodes the bedrock through a combination of abrasion and plucking. Abrasion occurs when the glacier grinds against the bedrock and wears it away, while plucking occurs when the glacier freezes onto the bedrock and pulls it away as the glacier moves downhill. Over time, this erosion can form a deep, steep-sided hollow or cirque on the mountainside. Cirques are often the starting point for the formation of other glacial landforms, such as u-shaped valleys and horn peaks. As a glacier continues to erode the mountainside, it can deepen and widen the cirque, creating a u-shaped valley. If multiple glaciers erode back-to-back cirques on a single mountain, it can leave behind a horn peak or a jagged, triangular peak at the mountain summit. Overall, cirques are a classic example of a landform produced by the slow, powerful forces of glaciation.

Detalhes da Resposta

The Stevenson's screen is a box used to house weather instruments that measure temperature, humidity, and other meteorological variables. It is raised about one meter above the ground to avoid the heat from the ground. When the screen is placed on the ground, it can absorb and radiate heat from the ground, which can affect the accuracy of temperature measurements. By raising it one meter above the ground, the screen is more exposed to the free atmosphere and less affected by the heat from the ground. Additionally, raising the screen helps to reduce the impact of raindrops entering the instruments during heavy rainfall. The height also helps to avoid the effects of nearby trees and other obstacles that could affect wind flow around the instruments and affect the measurements. Therefore, the main reason for raising the Stevenson's screen one meter above the ground is to ensure that the weather instruments inside are measuring the temperature and other meteorological variables accurately and without interference from external factors.
