Very hot magma rises toward the surface because it is less dense. The magma
becomes
as it cools, and it
back toward the
core.
form in the mantle where hot magma keeps rising
then cools and sinks again.
The movement of magma under the crust applies
plates
to tectonic
Rising hot magma pushes up on the crust, causing it to break and allowing
to form
happens where magma moving sideways and lava
forming new crust pushes plates in opposite directions.
Oceanic trenches form where denser oceanic crust is pushed under lighter
crust. The subducted plate begins to melt as it moves
Into the mantie.

Use the scenario below to answer the following question

Jerimiah and Nicko were discussing how well a vehicle uses its energy. They add a gallon of gasoline to the vehicle and observe the vehicle as their friend drives it in a circle around them. Jerimiah and Nicko hear the sound of the running engine, feel heat coming off of the exhaust and off the engine, and can see the vehicle move around them. After doing calculations they realize the vehicle did not travel nearly as far as they thought it would when it used the gallon of gasoline. Jerimiah claims that the energy must have been destroyed during its use, which is why they both heard the engine noises and felt the heat coming off. Nicko claims that the energy could not have been destroyed, but cannot determine what happened to all of the energy.

What can Nicko say that will explain why the energy was not destroyed during their test?
