hallo! heres you answer
^Extrusive igneous rocks are formed from the cooling lava that flows above the crust and Intrusive Igneous rocks are formed within the earth's interior.^
is the correct one because
-Intrusive, or plutonic, igneous rock forms when magma is trapped deep inside the Earth. ... Intrusive rocks have a coarse grained texture.
- Extrusive Igneous Rocks: Extrusive, or volcanic, igneous rock is produced when magma exits and cools above (or very near) the Earth's surface.
The answer should be its kinetic energy increases.
The kinetic energy of a particle means how fast they move, the faster they move, the more kenetic energy they have. In addition, when it moves faster and have more kenetic energy, their temperature becomes higher too.
Therefore, the answer is the first one.
