When molten rock flows or erupts through a crack on the earth's surface, it came from a Volcano.
<h3>What is a Volcano?</h3>
A volcano is a channel in Earth's crust through which molten rock flows. Volcanoes can develop from the subduction of a plate under another plate below the earth crust. At the boundaries where plates exist, molten magma rises in cracks between the two plates, leading to the formation of volcanoes.
Below the earth surface, molten rock is referred to as magma but as soon as it erupts above the earth's surface, it is referred to as Lava.
Therefor, according to the question, when molten rock flows or erupts through a crack on the earth's surface, it came from a volcano.

What are you trying to ask??
Answer:
A. P and S waves
Explanation:
P waves are compression waves while S waves are shear waves. P-waves are usually faster than S-waves (about 60% faster). P and S waves are called body waves because they move through the interior of the earth.
When an earthquake occurs, P and S waves are produced. A seismic recording station an be used to record the arrival of these two waves. Since the P wave is faster than the S wave, hence the P wave would first arrive at the station. The earthquake epicenter can be determined by the difference in time of arrival between the P and S wave.
