Question

Molten lava coming out of a Hawaiian volcano cools down and forms rock.

Which statement best describes the flow of energy in this scenario?

Energy moves from the surroundings to the lava.
Energy stays within the lava.
Energy stays within the surroundings.
Energy moves from the lava to the surroundings.

Answer 1

Answer:

Energy moves from the lava to the surroundings

Explanation:

• As the volcano erupts by shooting bits or rocks and lava out of the vent due to high intense heat and pressure, the molten lava freezes on the earth's surface and forms crystals.  

• The energy which was stored in the volcano earlier is released in the form ash, molten lava or magma and as result is thrown very far and wide away from the source so that it spreads down the volcano and its energy dissolves into the surroundings.

• The heat of the lava can melt everything and anything coming in its path, and Hawaiian volcanoes are known for their viscous flow of matter. The cooled basaltic lava is composed of heavy elements. As the heat escapes the lava gets hardened and darkens on the release of mechanical energy.
