Amplify - Earth's Features - Chapter 2 Vocabulary

What type of rock is likely to form in slow-moving water?

• Sandstone

• Siltstone

• Granite

• Basalt

What is a sedimentary rock?

• A type of rock formed from volcanic activity.

• A rock that is formed from the accumulation and compaction of sediment.

• A rock that is formed under extreme heat and pressure.

• A rock that is formed from the crystallization of minerals.

What is the process of sediment turning into rock called?

• Compaction

• Cementation

• Lithification

• Erosion

What does the color of rocks indicate about past environments?

• The color of rocks indicates the mineral composition only.

• The color of rocks can indicate the conditions of the past environment, such as whether it was wet or dry.

• The color of rocks is unrelated to environmental conditions.

• The color of rocks only indicates their age.

What is a fossil?

• A fossil is the preserved remains or traces of a once-living organism.

• A fossil is a type of rock formed from volcanic activity.

• A fossil is a living organism that has not yet died.

• A fossil is a modern animal that has been genetically modified.

In which environment is gravel most likely to build up?

• In still water environments

• In fast-moving water environments

• In sandy deserts

• In forested areas

What is an environment?

• An environment includes all the living and nonliving things in an area.

• An environment is only the living organisms in a specific area.

• An environment refers to the weather conditions in a region.

• An environment is a place where only humans live.

What is the difference between igneous and sedimentary rocks?

• Igneous rocks form from cooled magma or lava, while sedimentary rocks form from compressed sediment.

• Igneous rocks are formed by the erosion of other rocks, while sedimentary rocks are formed by volcanic activity.

• Igneous rocks are always found underground, while sedimentary rocks are found on the surface.

• Igneous rocks are formed from organic materials, while sedimentary rocks are formed from minerals.

What happens to sediment to form rock layers?

• Sediment gets compacted by the sediment above it and cements together to form a layer of rock.

• Sediment is melted by heat and pressure to form magma.

• Sediment is washed away by water and never forms rock layers.

• Sediment is transformed into gas and escapes into the atmosphere.

Why are sedimentary rocks important for understanding Earth's history?

• They are the most abundant type of rock on Earth.

• They contain clues about past environments, climate, and the organisms that lived during those times.

• They are formed from volcanic activity and provide information about Earth's core.

• They are primarily composed of minerals that are not found in other rock types.
