Answer:
The air present on earth is a mixture of gases which is mostly nitrogen and then oxygen.
Water is present in many forms on the earth, as solids in ice and glaciers, as liquid water in oceans, seas, river and streams, and as water vapor in the air.
Solid earth is made of three layers; the crust, mantle and core.
Life on earth is dependent on the various features of the earth such as the water, the atmosphere, the rotation of the earth on its axis as well as its sun which provides the energy needed to power activities here on earth.
Explanation:
The air present on earth is a mixture of gases which is mostly nitrogen and then oxygen. Other gases present include carbon dioxide, water vapor, and noble gases. Oxygen is the gas needed to sustain life on earth.
Water is present in many forms on the earth, as solids in ice and glaciers, as liquid water in oceans, seas, river and streams, and as water vapor in the air.
Solid earth is made of three layers; the crust, mantle and core. The surface of the earth is where most life and human activities exist. Many features are found on the surface of the earth such as mountains, plains, valleys, etc.
Life on earth is dependent on the various features of the earth such as the water, the atmosphere, the rotation of the earth on its axis as well as its sun which provides the energy needed to power activities here on earth.
Life on earth is very diverse. The parts of the earth which contains living things is known as the biosphere. Life on earth exist from microscopic forms such as bacteria and viruses to macroscopic forms such as animal and plant life.
