The quantity of heat a body absorbs to cause a change in temperature is given as:

  H  = mcΘ

H is the quantity of heat

m is the mass of the substance

c is the specific heat capacity

Θ is the temperature change

andreev551 [17]
What I did was I said the plates moved 3 centimeters per year and and times it by 100 million years and you get how far the plates have moved against each other. When they move that far against each other, the land would break and pile up to create mountains. Under the sea, the earth would collide and and create a chain of volcanoes. I got a 4/4 for this question, hope this helps you. Good luck!

As the days get shorter and the temperature drops, this bear _______________ to get ready for hibernation.
kodGreya [7K]
As the days get shorter and the temperature drops, this bear overeats and stores food as fat to get ready for hibernation.

When hibernate, bears will keep sleeping so they won't get any food from outside so they need to collect the food before hibernating. They have to eat more food than usual and stored it as fat to keep them from starving. The fats also help keep them warm as they are insulating the heat.
