Exploring Earth's Dynamic Changes

How does the rock cycle contribute to the formation of soil?

• By breaking down rocks into smaller particles

• By melting rocks into magma

• By solidifying magma into rock

• By preventing erosion

How does the rock cycle illustrate the concept of Earth's dynamic nature?

• By showing that rocks remain unchanged over time

• By demonstrating the continuous transformation of rocks

• By indicating that rocks are only formed through volcanic activity

• By proving that rocks are indestructible

What role does erosion play in the formation of canyons?

• It deposits sediments to fill valleys

• It wears away rock layers to create deep valleys

• It causes volcanic eruptions

• It forms new mountain ranges

Which layer of earth has the greatest pressure and temperature?

• inner core

• crust

• mantle

• outer core

What role do fossils play in understanding Earth's history?

• They provide evidence of past life and environmental conditions

• They are used to predict future weather patterns

• They help in the formation of new rocks

• They are used to measure the Earth's magnetic field

What is Magma when it reaches the surface of Earth?

• Lava
• Mafic Magma
• Felsic Magma
• None of these

How do weathering and erosion work together to change the Earth's surface?

• By creating new landforms through volcanic activity

• By breaking down rocks and transporting the particles

• By causing earthquakes

• By forming glaciers

What factors contribute to the weathering of rocks on Earth's surface?

• High pressure and temperature

• Wind, water, and temperature changes

• Volcanic eruptions

• Tectonic plate movement

Describe a scenario where the movement of tectonic plates could lead to the formation of a new ocean.

• When two plates move towards each other

• When two plates move apart from each other

• When one plate slides past another

• When a plate remains stationary

What type of plate boundary is this?

• Plate
• Divergent
• Convergent

  (subduction)

• Transform
