Which of the following is/ are the basis of scientists in dividing Earth’s lithosphere

into several plates?

• A. Distribution of major mountain belts

• B. Distribution of active volcanoes

• C. Earthquake epicenters

• D. All of the Above

What is the relationship between the distribution of active volcanoes, earthquake epicenters,

and major mountain belts?

• A. They are all concentrated along the boundaries of tectonic plates.

• B. They are evenly distributed across continents and ocean basins.

• C. They are primarily found in regions with high levels of human activity.

• D. They are unrelated geological phenomena occurring randomly across the Earth's surface.

Plates A and B show a divergent boundary. If plate C is

adjacent to both plates and does not show any relative

motion, what type of plate boundary is present between

A and C?

• A. convergent

• B. divergent

• C. Transform fault

• D. either A or B

What will happen if oceanic crust collides with continental crust?

• A. Continental crust will subduct because it is denser than oceanic crust.

• B. Oceanic crust will subduct because it is denser than continental crust.

• C. Continental crust will subduct because it is thinner than the oceanic crust

• D. Oceanic crust will subduct because it is thicker than the continental crust.

As South American and African plates move

gradually, what do you think will happen to

them?

• A. They will separate.

• B. They will grind past each other.

• C. They will bump into each other.

• D. They will stay where they are.

What kind of plate boundary is depicted in the picture

above, and which geological features are associated with

it?

• A. convergent - volcanic arc, trench

• B. divergent – rift valley and volcanoes

• C. convergent – mountain range, ocean

• D. convergent – volcanic island arc, trench

What is the driving force for the movement of the lithospheric plates?

• A. heat from the sun

• B. heat in the atmosphere

• C. unequal distribution of heat in the oceans

• D. unequal distribution of heat within Earth

Which of the following diagrams best illustrates the convection occurring in the mantle?

• 
• 
• 
• 

Supported by the information you can derive from the diagram, is each statement below evidence that Africa and South America were once joined together?

• A. 1-YES, 2-YES, 3-YES

• B. 1-YES, 2-NO, 3-YES

• C. 1-YES, 2-YES, 3-NO

• D. 1-NO, 2-YES, 3-YES

Plate Tectonic Theory has been widely accepted in the scientific community. What are some key lines

of evidence that supports this theory, and how have they contributed to its acceptance and

validation?

• A. The theory relies on the observation of comet tails in the night sky.

• B. Evidence includes the discovery of ancient fossils and the alignment of mountain ranges.

• C. The theory is mainly supported by the observation of meteorite impacts on the Earth's surface.

• D. The theory is supported by seismic data, magnetic striping on the seafloor, and the distribution of

  earthquakes and volcanoes.
