A. There were animals 3 billion years ago; they just weren't fossilized. B. Animals are warm-blooded; the ocean was too cold for animals.
Answer:
True
Explanation:
When we talk about fossils, we are referring to the remains of organisms that had once lived. These are traces of the organisms that existed in the distant past.
These fossil records help us to reconstruct plant and animal life in the past as well as their evolutionary processes, which can be either slow or rapid.
Fossil records reveal extinct species and help us to make sense of the evolutionary processes on earth.
Deforestation encourages flooding by allowing water to run off into streams
<u>Explanation</u>:
Deforestation plays vital roles in the flooding. The roots of the Trees prevent sediment runoffs and forests hold more water than farms or grasslands.Firstly the leaves in the trees will capture some amounts of water which will be eventually evaporated. Secondly, some quantity of water is absorbed by the tree's roots. Also,Tree roots hold the soil in place, reducing the movement of sediment that can shrink river channels downstream..
The process of deforestation will lead to dislodging of the topsoil. this makes the topsoil unstable and reduces its capacity to hold down the water
