When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt. Extremely high temperature and pressure cause the rock to melt and become liquid rock or magma. When a large body of magma has formed, it rises thorugh the denser rock layers toward Earth's surface

Lava (magma that has erupted onto the Earth's surface) is visually mesmerizing – as the molten rock flows downhill, lava exposed to the air cools to a deep black color, while the molten rock beneath glows bright orange.This magma can push through holes or cracks in the crust, causing a volcanic eruption.

Answer:

A hot spot

Explanation:

In geology, a hot spot is an area of the Earth’s mantle from which hot plumes rise upward, forming volcanoes on the overlying crust.

liberstina [14]

Answer:

D. The youngest volcano of the track occurs at one end of the track.

Explanation:

Hotspot tracks can be described as a process in which lines of islands, atolls, and seamounts are produced as plate continues to move away from the lava stream, it carries built up volcanoes with it; as these volcanoes cool and subside.

Examples are Hawaii, Yellowstone and Iceland hotspots.

What can scientists learn from magnetic striping patterns? Select the three correct answers.(2 points)
kari74 [83]

Hello. This question is incomplete. The full question is:

What can scientists learn from magnetic striping patterns? Select the three correct answers.

1. the cause of magnetic pole reversals

2. the year the next magnetic reversal will take place

3. the location of ancient faults caused by seismic activity

4. the exact location of the next earthquake along the California coast

5. the direction plates are moving relative to each other

6. the speed of one plate as it subducts below another plate

Answer:

The direction plates are moving relative to each other

The speed of one plate as it subducts below another plate

The location of ancient faults caused by seismic activity

Explanation:

Magnetic striping patterns are very valuable systems for understanding the factors that promote polar variability of the ocean floor. This is because these systems are formed exactly by changes in this polarity, presenting lines (similar to a zebra), which allow scientists to interpret them and have valuable information about the movement of the direction plates towards each other, the speed that a plate reaches the subduz below another plate and the location and old faults that were caused by the existence of seismic activities.
