Geology

Magma Formation (Magmatism)

Learning Objectives

• describe where the Earth’s internal heat comes from. 

• describe magma formation and what happens after the magma is formed

Multiple Choice

Molten rock refers to:

• A. magma

• B. lava

• C. volcanic ash

• D. caldera

Multiple Choice

Which of the following statements describes a mineral?

• A. It is natural occurring, organic, solid, with crystal structure, and definite composition

• B. It is man-made, inorganic, solid, with crystal structure, and definite composition

• C. It is naturally-occurring, inorganic, solid, with crystal structure, and definite composition

• D. It is naturally-occurring, inorganic, solid, with crystal structure, and indefinite composition

Multiple Choice

Which among the three rock types are formed due to the melting of rocks brought about by volcanic activities?

• A. Igneous rocks

• B. Sedimentary rocks

• C. Metamorphic rocks

• D. Pleiomorphic rocks

Multiple Choice

Which statement is an example of biological weathering?

• A. A tree in front yard spreads its roots in a sidewalk, pushing the sidewalk up and causing it to crack

• B. Over the course of two years, the top layer of soil at a Bukidnon farm is blown away.

• C. Rainfall collects in a crack in a rock. When the temperature drops, the water freezes cracking the rock

• D. A very large storm occurs along the coast. The waves washed away sands in the shore.

Multiple Choice

Which statement is NOT true for sedimentary rocks?

• A. Sedimentary rocks often have layers showing deposition of sediment at different time periods.

• B. Sedimentary rocks often have fossils trapped within them.

• C. Sedimentary rocks often have layer structures of crystals caused by effect of heat and pressure.

• D. Sedimentary rocks consist of layers of lots of small particles and are often porous.

Multiple Choice

• C. Feldspar

• D. Quartz

Multiple Choice

What type of rock is formed by heat and pressure?

• A. Igneous

• B. Foliated, Non-Foliated, and Volcanic

• C. Volcanic, Metamorphic, and Rocky

• D. Metamorphic, Igneous, and Sedimentary

Multiple Choice

What type of rock is formed by weathering and erosion?

• A. Sedimentary

• B. Foliated

• C. Metamorphic

• D. Igneous

Multiple Choice

• D. precipitation of seawater

Fill in the Blanks

is a representation of the transition of the three rock types associated with Earth’s processes such as weathering, deposition, volcanic eruptions, erosion, and change in temperature and pressure.

Fill in the Blanks

refers to the breaking or decomposition of rocks due to external factors that can be caused by climate, weather, chemical compounds, or living organisms. Weathering can be identified by formation of cracks, spaces, or small fractures on rocks.

Fill in the Blanks

is geological process which involves the addition of sediments, soil and rocks to a land mass.

Fill in the Blanks

refers to the movement of rocks, debris, and other products of weathering, from one location to another.

Fill in the Blanks

are rocks that are formed from an already existing rock due to high temperature and pressure.

Open Ended

Open Ended

What do you call the remains of a plant or animal that existed in a past geological age and that has been excavated from the soil?

Open Ended

Why rock cycle is called a never-ending cycle?

Open Ended

What is the difference between magma and lava?
