Answer:
1.The lithosphere is made up of rocks from two of the Earth's major layers. It contains all of the outer, thin shell of the planet, called the crust, and the uppermost part of the next-lower layer, the mantle. ... That depth is defined as the bottom of the lithosphere.

4.The different layers of the atmosphere. The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth's surface, is called the exosphere.
5. Ecological balance is a term used to describe the equilibrium between living organisms such as human being, plants, and animals as well as their environment. ... Therefore, this balance is very important because it ensures survival, existence and stability of the environment.
