Question

]The steps in the formation of extrusive igneous rocks are listed below in an incorrect order. 1. Rock melts due to high temperature. 2. Rock is buried deep under Earth's surface. 3. Magma is forced out of Earth's surface during volcanic eruption. 4. Magma cools and crystallizes. Which of these best shows the correct order of steps in the formation of extrusive igneous rocks?

Answer 1

1. Rock is buried deep under Earths surface. 2. Rock melts due to high temperature. 3. Magma is forced out of Earth's surface during volcanic eruption. 4. Magma cools and crystallizes. Rock from underneath the ground has to heat up and be pressurized first. After enough pressure and heat are applied the volcano will erupt. Extrusive igneous rocks are formed when lava cools on Earth's surface above ground.
