Plate tectonics revised 23 Sep

What natural phenomena are explained by the theory of plate tectonics?

• Ocean currents
• Weather patterns
• Solar eclipses
• Earthquakes and volcanic activity

Which of the following best describes the asthenosphere?

• A solid layer that supports the lithosphere.
• A semi-fluid layer beneath the lithosphere.
• The outermost layer of the Earth.
• A layer composed entirely of molten rock.

What is the primary characteristic of the lithosphere in relation to plate tectonics?

• It is the innermost layer of the Earth.
• It is composed solely of the Earth's crust.
• It is a liquid layer beneath the crust.
• It is divided into several large and rigid plates.

Which of the following is a consequence of tectonic plate movement?

• Earthquakes and volcanic activity
• Increased ocean salinity
• Formation of new stars
• Stable weather patterns

What geological feature is typically formed at divergent boundaries?

• New oceanic crust
• Mountain ranges
• Volcanic islands
• Oceanic trenches

What type of plate boundary occurs when two tectonic plates collide?

• Subduction Boundary
• Divergent Boundary
• Transform Boundary
• Convergent Boundary

Which of the following statements about convergent boundaries is true?

• They have no geological significance.
• They can lead to the formation of mountains or trenches.
• They occur when two plates move apart.
• They are characterized by plates sliding past each other.

At which type of boundary do tectonic plates slide past one another horizontally?

• Transform Boundary
• Divergent Boundary
• Convergent Boundary
• Subduction Zone

Which of the following is an example of a transform boundary?

• Mid-Atlantic Ridge
• Mariana Trench
• San Andreas Fault
• Himalayas

What type of tectonic plate boundary is exemplified by the San Andreas Fault?

• Transform Boundary
• Convergent Boundary
• Divergent Boundary
• Subduction Zone
