Answer: By the rain, the animals that live in the ocean, and in the air.
Explanation:
The ocean plays an important part in the carbon cycle. Overall, the ocean is called a carbon ‘sink’ because it takes up more carbon from the atmosphere than it gives up.
Antarctic phytoplankton
Antarctic phytoplankton, Fragilaria kerguelensis (large group), Nitzschia sp. (single small cell on the left) and partial cell of Thalassiosira sp.
Carbon dioxide from the atmosphere dissolves in the surface waters of the ocean. Some of the carbon dioxide stays as dissolved gas, but much of it gets turned into other things. Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter. Many organisms use carbon to make calcium carbonate, a building material of shells and skeletons. Other chemical processes create calcium carbonate in the water. The using up of carbon by biological and chemical processes allows more carbon dioxide to enter the water from the atmosphere.
Answer:
They have a thinner atmosphere.
Explanation:
Venus has a very dense atmosphere compared to Mars and Mercury. This causes many small meteorites and asteroids to break apart before they reach the surface. Thus, Venus has fewer craters than Mars and Mercury.
Dependent. Density dependent factors is what is being described.
