This is True.
Southeast Asia has an abundance of natural resources, they're just not used as much as they should be.
The Earth’s interior is composed of several layers: the crust, the mantle and the core. Scientists used waves and their speed to study the Earth's interior. The speed of seismic waves is affected by the properties of the material the waves pass through. The stiffness of material affects the speed of these waves. P-waves, or pressure waves, go through both liquids and solids, while S-waves, or shear waves go through solids but not liquids. The following helped scientists understand that Earth's interior is liquid: S waves cannot travel through liquids. Correct answer: D
Answer:
Soils are the key ingredient for the plants and crops to grow. A large amount of soil is eroded every year due to the practice of farming. This is about 25 billion tons of soils.
Due to the various type of agricultural practices, the topsoil comprising the valuable minerals are continuously eroded by factors such as wind and water. This results in the increasing loss of soil fertility, and also it can lead to the occurrence of droughts, sandstorms, and dust bowls.
Dust bowls are the region where there occurs no rainfall and absence of vegetation, and soils are eroded drastically making a sandy dust environment, and affecting the ecosystem.
In order to prevent these effects, certain steps must be taken, and they are as follows-
- Planting more trees and crops so that the wind cannot cause much impact on the area.
- The waste vegetative particles and matters must be allowed to distribute evenly over the surface of these areas, so that wind cannot easily transport these sediments.
- Mulching of the soil must be done.
- By constructing the retaining walls.
