Coal is formed when

• sediments cover dead marine organisms and heat converts them in to complex, energy-rich carbon molecules.
• deposits of methane are subjected to high pressure until they condense into crystals.
• swamplands are buried by sediment, the added weight creates heat and pressure that converts the plants into coal.
• oil is put under pressure and hardens.

Base your answer to the following question on the diagram which represents a profile of a mountain glacier in the northern United States. Over a period of years, this glacier gains more snow mass than it loses. What will be the most likely result of this gain?

• The glacier will decrease in size, and the ice front will retreat.

• The glacier will decrease in size, and the ice front will advance.

• The glacier will increase in size, and the ice front will retreat.

• The glacier will increase in size, and the ice front will advance.

Geologists have evidence of an igneous rock formation under Earth’s outer layer. Is it possible that material from this rock formation could ever form sedimentary rock on Earth’s surface?

• No, sedimentary rock can only form out of material from other sedimentary rock. There is no way that sedimentary rock can form from material in igneous rock.

• No, sedimentary rock forms at Earth’s surface because energy from the sun causes rock to weather, but igneous rock under Earth’s outer layer is not exposed to energy from the sun.

• Yes, energy from Earth’s interior can cause igneous rock to break into small rock pieces that can form sedimentary rock.

• Yes, if igneous rock is moved to Earth’s surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock.
