Earth structure and plate tectonic

1. Ordering the thickness of the Earth's structural layers from greatest to least?

• inner core > outer core > mantle > crust

• outer core > inner core > mantle > crust

• Earth's crust > mantle > inner core > outer core

• Mantle > outer core > inner core > crust

2. Which is the main component of the continental crust?

• Silicon (Si) and Aluminum (Al)

• Silicon (Si) and Magnesium (Mg)

• Aluminum (Al) and Magnesium (Mg)

• Aluminum (Al) and Carbon (C)

Which of the following is correct?

• Viscous rock that flows to the earth's surface is called magma.

• Viscous rock that flows to the earth's surface is called lava.

• Magma and lava have different mineral compositions.

• Magma and lava are viscous rock that flows upwards towards the earth's surface.

Which statement is incorrect about our world?

• The Earth's core is the layer with the highest temperature.

• The mantle is the thickest layer.

• The earth's crust is the thinnest layer.

• Magma ejected from volcanoes comes from the Earth's mantle.

What causes magma in the Earth's mantle to circulate?

• Pressure within the Earth's mantle.

• Thermal energy from the earth's core.

• Force from the Earth's rotation.

• Components that are both solid and viscous.

Which conclusion is incorrect?

• The continental crust is made up of granite (Sial).

• The oceanic crust is made up of basalt (Sima).

• The oceanic crust is thinner than the continental crust.

• The oceanic crust is older than the continental crust.

Which is not a cause of earthquakes?

• The earth's crust expands and contracts equally.

• Atomic bomb experiment

• A violent volcanic eruption.

• Collision of tectonic plates.

What caused by the movement of matter in the outer core?

• Tsunami

• Earthquake

• Volcanic eruption

• Earth's magnetic field

Is there a chance of a volcanic eruption in Thailand? Why?

• Have chance, the tectonic plates are constantly moving.

• Have chance, magma may push up through cracks in the rock layer.

• No chance, Thailand has no cracks in the rock layer at all.

• No chance, the volcano in this country is an extinct volcano.

Which is the most appropriate application of scientific knowledge to study the structure of the earth?

• Using the properties of light waves to study the structure of the earth.

• Using the properties of seismic waves to study the structure of the earth.

• Using the properties of electromagnetic waves to study the structure of the earth.

• Using the reflection properties of waves to study the structure of the earth.
