<u>Answer:</u>
<em>The geological process taking place in the convergent boundaries is what is called subduction. </em>
<em></em>
<u>Explanation:</u>
The tectonic plates moves from side to another and they are forced to sink because of substantial gravitational forces to the mantle.
The crust of the earth is continuous however it is divided into pieces, the pieces, therefore, is one called tectonic plates, and they move close to each other through the power of convection cycles contained in the mantle below the crust enabling the plates to move freely.
Answer:
Option: D. It cooled very slowly.
Explanation:
Iceland is known as the Land of Fire. The country is present in the plate boundary of the North American and Eurasian tectonic plates. Being on the top of the Ring of Fire, it has active volcanoes. Hexagonal basalt columns formed from a volcanic eruption. Basalt columns are the result of a cooling process that changes the appearance of the lava. Basalt is a volcanic rock rich in iron and magnesium created from the heated magma that emerges as lava during an eruption.
