The statement underlying mantle layer is molten where convection currents cause the movement of the lithospheric plates explains the movement of these lithospheric plates.
<h3>What is tectonic plate movement? </h3>
The theory discusses how Earth's surface is composed out of rigid slabs of <em>rock</em> that are known as plates. These <u>large pieces </u>of plates under the Earth's surface are regarded as the lithosphere.
Therefore, convection currents that appear in the mantle lead to movements in the plates due to the flow of current to heat up the mantle.

The cold Arctic Ocean.
Answer:
Below
Explanation:
An understanding of the structure of the Earth is important for many reasons
1. It can help us understand things that happen on the surface, like the magnetic field. The structure of the Earth explains that.
2. Things like tectonic plates severely affect the planet, such as the creation of many natural disasters. Understanding them helps us better prepare and anticipate them.
3. Understanding the structure of the Earth can help us identify the location of important natural resources (like different metals)
4. In the production of things like geothermal energy we need to understand the Earth's structure to know where we will get the most heat
<u>A) Possible trigger for this tsunami:</u>
The reason which might be possible for the tsunami is massive sea waves of water which are resulted from the under sea earthquakes which struck in the gulf of Alaska triggered tsunami.
