1. Lithosphere
2. Hydrosphere
3.atmosphere
4. Biosphere
The lithosphere/geosphere is made of the earth's core, the mantle, crust, ocean floor,mountains, sand, etc.The hydrosphere is made of everything water such as oceans, rivers, lakes, rain, and snow.The atmosphere is made of gasses such as oxygen, and hydrogen.Finally the biosphere is all that has life such as plants, animals, people, insects, etc.
When the circular muscles contract, the earthworm stretches, becoming longer and thinner. The earthworm uses its setae to anchor the front of its body in the soil. Now the longitudinal muscles contract and the earthworm becomes shorter and wider or it bends from one side to the other, pulling the body forward.
I think the answer is most likely A

Answer:
Increase occur in skin diseases and decrease occurs in the Earth's average temperature.
Explanation:
If both Carbon Dioxide and Ozone levels began to decrease, increase occur in skin diseases and decrease occurs in the Earth's average temperature. The decrease in ozone levels allows more UV radiation to reach the Earth's surface which lead to various diseases such as skin cancer, cataracts, and weakened immune systems. The atmospheric carbondioxide gas is responsible for the increase of surface temperature by trapping reflected solar radiations so decrease in carbondioxide concentration will leads to lower surface temperature.
