Science Quizizz - Grade 10

What caused the abundance of active volcanoes along the Ring of Fire?

• Widening of the oceans

• Formation of mountain ranges

• Movement of the tectonic plates

• occurrence of earthquake epicenters

Why does the oceanic crust sink beneath the continental crust at the subduction zone?

• The oceanic crust has a greater density.

• The oceanic crust is pulled downwards by the Earth’s magnetic field.

• The oceanic crust is pushed from the ridge

• The continental crust has a less dense composition.

The lithospheric plates are said to be moving slowly. What is the driving force that facilitates this movement?

• gravitational force

• magnetic force at the poles

• convection current in the mantle

• the movement of the crust

From the seismogram, the distance to the epicenter can be determined by measuring _______________.

• the arrival time of surface wave

• the difference in the arrival times of P wave and S wave

• the ratio of the amplitude of the largest P wave and S wave

• the speed of the surface wave

Peer scientists reviewing Wegener's hypothesis of continental drift rejected his notion because____________.

• his evidence was too few to make a valid conclusion

• he lied by including false evidence

• his evidence was not clear in showing how continents were joined

• he did not explain how continents move and what moves them

How will you relate the distributions of mountain ranges, earthquake epicenters and volcanoes?

• they have different locations.

• Most mountain ranges are found in places where volcanoes and/or earthquake epicenters are also situated.

• Mountain ranges are found only in places where earthquake epicenters are situated.

• Mountain ranges are found only in places where volcanoes are situated.

During the 1960s, scientists were already equipped with gadgets needed to explore the deep ocean. What discovery about the ocean floor is associated with the seafloor spreading?

• Mountains are denser than the mantle.

• The rotational poles of the earth have migrated.

• The crust of the continents is denser than the crust of the ocean.

• The crust of the ocean is younger relative to the age of the crust of the continents

What theory explains the movement of lithospheric plates?

• Plate Tectonic Theory

• Continental Drift Theory

• Convection Theory

What happens at convergent plate boundary?

• Plates move towards each other

• Plates move in opposite directions

• Plates move in the same direction, but at different speeds

• Plates move either in opposite directions or in the same direction, but at different speeds

Which of the following statements is NOT TRUE about plate boundaries?

• Plate boundaries are the edges where two plates meet

• Plate boundaries are rigid sections of the lithosphere that moves as a unit.

• Plate Boundaries are categorized into three distinct types.

• Plate boundaries are differentiated by the type of movement they exhibit.
