• Divergent

• Convergent: Continental-Continental

• Convergent: Continental-Oceanic

• Convergent: Oceanic-Oceanic

• Transform

What type of plate boundary is shown?

• Divergent

• Convergent: Continental-Continental

• Convergent: Continental-Oceanic

• Convergent: Oceanic-Oceanic

• Transform

Which statement/s is/are INCORRECTLY stated?

• I. Oceanic crust is denser than continental crust.

• II. Iron components of the continental crust contributes to its high density.

• III. All plate boundaries are related to volcanism.

• IV. Divergent movement is related to powerful earthquake

Answer explanation

I. Oceanic crust is denser than continental crust - This is correct.

II. Iron components of the continental crust contributes to its high density - Crust is high in Silicates NOT iron

III. All plate boundaries are related to volcanism - Transform plate boundaries are not related to volcanism

IV. Divergent movement is related to powerful earthquake - Divergent movement is related to WEAK earthquakes

What land formation is formed in the image?

• Mid-ocean ridge

• Rift Valley

• Trench

• Volcano

Answer explanation

Rift Valley is for Land (Continental Crust)

Trench is formed because of subduction and pictures shows spreading

Volcano formation is more associated with convergent plate boundary, the picture shows a divergent plate boundary

Which among the following illustrates the process of subduction?

• 
• 
• 
• 

All of the following plate boundaries can cause powerful earthquakes EXCEPT?

• Convergent plate boundary

• Divergent plate boundary

• Transform plate boundary

• Transverse plate boundary

Answer explanation

DIVERGENT PLATE BOUNDARY is where WEAK earthquakes occur

What is the most common (dominant) plate boundary in the Pacific Ring of Fire?

• Transverse plate boundary

• Transform plate boundary

• Divergent plate boundary

• Convergent plate boundary

Identify which layer of the earth do tectonic plates move

• Asthenosphere

• Outer core

• Lithosphere

• Lower Mantle

Answer explanation

Tectonic plates float on the ASTHENOSPHERE

What are the two features that form near every subduction zone?

• Mid Ocean Ridges and Trenches

• Volcanoes and Trenches

• Rift Valleys and Mid Ocean Ridges

• Volcanoes and Rift Valleys

Answer explanation

Rift valleys and mid-ocean ridges are NOT formed because of subduction

At which tectonic plates will most likely experience catastrophic volcanic eruption, devastating earthquake, and tsunami?

• J and L

• B and F

• B and D

• N and I

Answer explanation

J and L is bounded by a CONVERGENT PLATE BOUNDARY

B and F; N and I are bounded by DIVERGENT plate boundary

B and D is bounded by TRANSFORM plate boundary
