Question

12 a mining company was comparing rock samples from two different mines. their observations showed that the rock samples were two different types of rock. how could energy have played a role in the different rock types forming? a energy from different sources leads to different types of rock. energy inside earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces of rock. b energy causes different types of rock to change in different ways. energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock. c energy changes rock on different continents in different ways. each continent on earth has different rock that might form liquid rock or small rock pieces when exposed to energy. d energy caused one rock type to form, but not the other. rock that forms because of energy is a different type of rock than rock that forms without energy.

Explanation:

Energy from various sources has distinct effects on rocks. Internal - Earth energy can melt rocks into magma (liquid rock), while solar - energy can cause weathering, breaking rocks into smaller pieces. Option a correctly describes how different energy sources lead to different rock - related processes. Option b inaccurately specifies which rock types change in specific ways; energy can affect all rock types in multiple ways, not just igneous and sedimentary as described. Option c focuses on continents rather than energy sources. Option d is incorrect as all rock formation is related to energy in some way.

Answer:

A. Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces of rock.
