Assessment on Continental Drift, Plate Tectonics, and Earth's Processes

What is the theory of continental drift?

• The idea that continents have always been in the same location
• The hypothesis that continents move across Earth's surface over time
• The belief that continents are stationary and unchanging
• The concept that continents are made of water

Which layer of the Earth is composed mostly of iron and nickel?

• Crust
• Mantle
• Outer core
• Inner core

What causes the movement of tectonic plates?

• Earth's rotation
• Ocean currents
• Convection currents in the mantle
• Gravitational pull from the moon

Which process involves the breakdown of rocks at Earth’s surface?

• Erosion
• Weathering
• Sedimentation
• Deposition

How does soil formation begin?

• Through the deposition of organic matter
• By volcanic eruptions
• Through the weathering of rocks
• By tectonic shifts

What are the main types of plate boundaries?

• Transform, convergent, divergent
• Static, dynamic, rotational
• Continental, oceanic, mixed
• Primary, secondary, tertiary

Which layer of the Earth is the thinnest?

• Crust
• Mantle
• Outer core
• Inner core

What is erosion?

• The process of rock formation
• The movement of sediment by wind, water, or ice
• The solidification of magma
• The creation of new landmasses

Which type of weathering involves changes in the chemical composition of rocks?

• Physical weathering
• Biological weathering
• Chemical weathering
• Mechanical weathering

What evidence supported the theory of continental drift?

• Climate data
• Fossil records and geological similarities across continents
• Ocean temperature
• Earth's gravitational field
