ES Chapt 3 Test Rock Cycle

Front

What is the significance of gastropods in sedimentary layers?

Back

Gastropods lived for a long time as they are found across multiple sedimentary layers, indicating their long existence in geological history.

Front

What do ripple marks in sedimentary rocks indicate about their formation?

Back

Ripple marks suggest that the rocks formed along a beach or stream bed, where water movement created these patterns.

Front

What type of rock is rhyolite?

Back

Rhyolite is an igneous rock that is typically light in color and has a high silica content.

Front

What is the process called when rocks break into smaller pieces due to natural elements?

Back

The process is called weathering.

Front

What are the primary sources of energy that drive Earth's rock cycle?

Back

The energy that drives Earth's rock cycle comes from Earth's interior and the sun.

Front

Define sedimentary rock.

Back

Sedimentary rock is formed by the accumulation and compaction of mineral and organic particles, often in layers.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind or water.

Front

Explain the difference between weathering and erosion.

Back

Weathering is the breaking down of rocks into smaller pieces, while erosion is the movement of those pieces from one location to another.

Front

What are fossils, and how are they related to sedimentary rocks?

Back

Fossils are the preserved remains or traces of ancient organisms, often found in sedimentary rocks where they were buried.

Front

What role do sedimentary layers play in understanding geological time?

Back

Sedimentary layers help geologists determine the relative ages of fossils and the history of life on Earth.
