Exploring the Rock Cycle

What are the three main types of rocks?

• Igneous, Sedimentary, Metamorphic

• Granite, Limestone, Shale

• Coal, Quartz, Clay

• Basalt, Sandstone, Slate

What is the process of sedimentation?

• Sedimentation involves the mixing of particles in a fluid to create a suspension.

• Sedimentation is the process of particles settling out of a fluid due to gravity.

• Sedimentation is the process of evaporation of water from a surface.

• Sedimentation is the process of particles being dissolved in a fluid.

How do metamorphic rocks form?

• Metamorphic rocks originate from the erosion of sedimentary layers.

• Metamorphic rocks form from the alteration of existing rocks under heat and pressure.

• Metamorphic rocks form from volcanic activity.

• Metamorphic rocks are created by the cooling of magma.

What is the rock cycle?

• The rock cycle is a method of cooking rocks.

• The rock cycle is the process of transformation of rocks through geological processes.

• The rock cycle refers to the formation of minerals only.

• The rock cycle is the process of recycling rocks into new materials.

What is the difference between intrusive and extrusive igneous rocks?

• Intrusive rocks have larger crystals due to slow cooling, while extrusive rocks have smaller crystals due to rapid cooling.

• Extrusive rocks have larger crystals due to slow cooling.

• Intrusive rocks are formed from lava on the surface.

• Intrusive rocks cool rapidly and are found on the surface.

How does heat and pressure affect rocks?

• Heat and pressure have no effect on the mineral composition of rocks.

• Heat and pressure cause rocks to dissolve completely.

• Heat and pressure turn rocks into igneous rocks by melting them.

• Heat and pressure transform rocks into metamorphic rocks by causing recrystallization and realignment of minerals.

What is the role of erosion in the rock cycle?

• Erosion only affects the surface of the Earth without changing rocks.

• Erosion breaks down and transports rocks, facilitating the formation of sedimentary rocks in the rock cycle.

• Erosion creates igneous rocks directly from magma.

• Erosion has no impact on the rock cycle.

What are the characteristics of metamorphic rocks?

• Metamorphic rocks are always igneous in nature.

• Metamorphic rocks are formed from volcanic activity.

• Metamorphic rocks are characterized by foliation, mineral alignment, and changes in texture and composition due to heat and pressure.

• Metamorphic rocks have a glassy texture and no mineral alignment.

How do volcanic eruptions contribute to the rock cycle?

• Volcanic eruptions destroy all types of rocks.

• Volcanic eruptions create igneous rocks and contribute to the formation of sedimentary and metamorphic rocks.

• Volcanic eruptions have no impact on the rock cycle.

• Volcanic eruptions only create sedimentary rocks.

What is the difference between foliated and non-foliated metamorphic rocks?

• Non-foliated rocks have a layered structure; foliated rocks do not.

• Foliated rocks are always harder than non-foliated rocks.

• Foliated rocks are formed from igneous processes; non-foliated rocks are not.

• Foliated rocks have a layered structure; non-foliated rocks do not.
