2.4 Earth's Dynamic Rock Cycle

Which of the following best describes the rock cycle?

• A static process where rocks remain unchanged
• A continuous geological recycling system
• A one-way transformation of rocks
• A process that only occurs underground

What are the three main rock types discussed in the presentation?

• Granite, Marble, and Sandstone
• Igneous, Sedimentary, and Metamorphic
• Volcanic, Sedimentary, and Crystalline
• Limestone, Basalt, and Slate

Which type of weathering involves chemical changes to rock composition?

• Mechanical weathering
• Physical weathering
• Chemical weathering
• Thermal weathering

What is an example of mechanical weathering?

• Acid rain dissolving minerals
• Oxidation changing rock color
• Ice wedging in rock cracks
• Water dissolving rock materials

Which agents contribute to rock erosion?

• Water and wind only
• Water, wind, ice, and mass movement
• Gravity and temperature
• Chemical reactions alone

What factors influence soil formation?

• Time and temperature only
• Parent rock and climate
• Time, parent rock, climate, biotic factors, and topography
• Wind and water movement

How can an igneous rock potentially become a sedimentary rock?

• Through immediate crystallization
• By direct chemical reaction
• Through the rock cycle process of weathering and deposition
• By sudden temperature changes

What role does water play in the rock cycle?

• It has no significant impact
• It only moves sediment
• It causes mechanical and chemical weathering
• It prevents rock transformation

What is oxidation an example of?

• Mechanical weathering
• Chemical weathering
• Erosion
• Rock formation

Which process involves compacting sediments to create a new rock type?

• Metamorphism
• Igneous formation
• Sedimentary rock formation
• Volcanic eruption
