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?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes

Using a pedometer, you walk 3000 steps in 20 minutes, so your speed is 150 steps/min. each of your steps is 0.7 m long. what is your speed? 150 steps/min=/s=/h
