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.

Answer: Subduction
Explanation:
Because it was in the lesson
Hi,
I can help you with that.
Earth is a sphere. The reason the earth is a sphere is because a long time ago a big rock called earth was created, later when atmosphere was forming the earth's centrifugal force aka rotation shaped earth into a sphere by burning down high peaks and bumps.
Hope this helps.

Answer:
<u>Called as mantel melting</u>
Explanation:
- The mantel rocks can break and melt without the increase in temperature due to the overexerted pressure of the rocks.
- This process is called decompression melting. Rocks can melt in the mantel due to dehydration thus producing molten magma and lava.
- As the rocks don't melt homogeneously there is a complex mixture of mineral content during the subduction and presence of volatile substances like the water or CO2.
