Internal Structure of Earth

In what category of layers of earth are the following : lithosphere, asthenosphere, mesosphere, outer and inner core?

• Compositional

• Continental

• Mechanical

• Geological

What is the layer of Earth that composed of nickel-iron alloy?

• crust

• core

• mantle

• mesosphere

How do rocks in asthenosphere can easily deform compare to lithosphere?

• Because asthenosphere can be found above lithosphere.

• Because the rocks in asthenosphere are mostly nickel.

• Because the lithosphere has greater pressure compare to asthenosphere.

• Because of extreme pressure and temperature to asthenosphere than lithosphere.

Which layer of Earth generates Earth's magnetic field

• Crust

• Mantle

• Inner core

• Outer core

Which of the following geologists proposed the Continental Drift Theory?

• Alfred Wegener

• Abraham Ortelius

• Alexander van Humboldt

• Antonio Snider-Pellegrini

According to Continental Drift Theory, how do geologist come up with the word "Pangaea"?

• He proposed that the Earth originated as a single, huge landmass.

• He proposed that some of the land on Earth submerged in ocean.

• He proposed that once Earth revolve around the sun, land are automatically separating from each other.

Based on the given illustration, how it could be one of the useful evidence for Continental Drift Theory?

• Continents are fit together

• There are some fossils on different continent

• Mountain ranges can be found with other continent

What will be the sign of new seafloor spreading in oceanic lithosphere?

• Once two lithosphere move apart from each other

• Once the magma rises from the mantle

• Once the fill the gap between two plates

• Once the magma readily cools and solidifies

When will be the time that rocks in lithosphere possess weak magnetism?

• normal polarity

• reverse polarity

• normal attraction
