What are the two categories of internal heat sources of the Earth?

• Solar heat and geothermal heat

• Primordial heat and radioactive heat

• Convection heat and conduction heat

• Environmental heat and artificial heat

Which of the following best describes the process of magmatism?

• The cooling of rocks on Earth's surface

• The movement of magma within Earth's crust and upper mantle

• The erosion of mountains by wind

• The formation of sedimentary rocks in oceans

Why does magma rise towards Earth's surface?

• It is denser than the surrounding rock

• It is less dense than the surrounding rock and has lower viscosity

• It is heavier than water

• It is attracted by the sun's gravity

What are the two primary types of geological processes that involve magma?

• Erosion and sedimentation

• Weathering and deposition

• Plutonism and volcanism

• Glaciation and desertification

Which of the following processes contributes to the formation of new seafloor?

• Erosion of coastal cliffs

• Magmatism and the cooling of magma at mid-ocean ridges

• Deposition of river sediments

• Movement of glaciers

What was the giant landmass proposed by Alfred Wegener in the Continental Drift Theory called?

• Laurasia

• Gondwana

• Pangaea

• Atlantis

Which type of stress acts in opposite directions, pulling rock apart?

• Compressional Stress

• Tensional Stress

• Shear Stress

• Confining Stress

Why is limestone more susceptible to weathering compared to igneous rock?

• Limestone has a higher temperature threshold.

• Limestone is harder than igneous rock.

• Limestone reacts more quickly with water and acids, speeding up weathering.

• Limestone is less porous than igneous rock.

What type of metamorphism occurs due to high pressure along fault zones?

• Contact Metamorphism

• Regional Metamorphism

• Dynamic Metamorphism

• Thermal Metamorphism

Which factor influences the rate at which weathering occurs?

• The color of the rock

• The density of the rock

• The mineral composition and climate

• The age of the rock
