Answer:
heres a ppt i had to do about global warming and greenhouse effect just check the global warming part
Explanation:
1. My predictions about the changes in sea level have been relatively close to the actual rise of the sea waters, though it has been different than the general predictions of the numerous models of the countries. The predictions that I have made about the rise of the sea level have been based on the rate of melting of the polar ice, but also on the isostatic rebound that occurs because of it, and the influence that the greenhouse gasses have on the global temperature. The estimates that I made were showing a rise of only few centimeters, unlike the several meters predicted by most of the models. The closest model to what I have predicted is the Russian model, which is very different than the others.
2. The sea level variations are not very easy to predict, nor do they have any particular cycle that is repeating on approximately the same time. There are numerous factors that influence the variations of the sea level, such as the global temperature, with higher temperature meaning higher sea levels, and lower temperature meaning lower sea levels. The isostatic rebound of the continental land masses should also be taken in consideration, as the continents lift up when they don't have pressure on top of them from the ice, and sink down when they do have large ice masses on them, thus it can influence where the water can penetrate and where it can't. The position of the landmasses, composition of the atmosphere, as well as the geological activities, all have big influence on the variations of the sea levels, be it going up or down.
This statement is true about the effect of floods on the ecosystem. Flood impact individuals or communities as well and have social economic and environmental consequences.
<h3>
What are natural disasters and its effect?</h3>
Natural Disasters are catastrophic events that led to atmospheric geological and hydrological events which cause drought, flood, earthquake, hurricanes, and landslides.
Natural disasters cause damage to property, financial loss, loss of life.
People lose their homes, putting their lives in danger to survive in disasters time.
Therefore this statement is true.

The Earth's mantle is very important. It is important for the Earth's crust evolution, as well as being the provider of thermal and mechanical forces for plate tectonics. The mantle is what covers the most part of Earth inside if it is not there, then the heat of the core will burn the Earth's crust. And the mantle does make up 84% of Earth's volume, so that wouldn't be good!
