Rocks and Rock cycle

What are the three major types of rocks?

• Igneous, metamorphic, and sedimentary.

• Granite, limestone, and basalt.

• Clay, silt, and sand.

• Coal, oil, and natural gas.

What is metamorphism?

• The process of weathering rocks into soil.

• The process by which existing rocks are transformed into metamorphic rocks due to heat and pressure.

• The process of forming igneous rocks from molten magma.

• The process of eroding rocks through wind and water.

What is an igneous rock?

• A type of rock formed from the cooling and solidification of molten rock (magma or lava).

• A rock that is formed by the accumulation of sediments over time.

• A rock that is formed through the metamorphosis of existing rocks under heat and pressure.

• A type of rock that is formed from the crystallization of minerals in water.

What are minerals?

• Minerals are naturally occurring inorganic substances with a definite chemical composition and crystal structure.

• Minerals are organic compounds found in living organisms.

• Minerals are man-made substances used in construction.

• Minerals are liquids that form from volcanic activity.

What is erosion?

• Erosion is the process by which rocks and soil are worn away and transported by natural forces like water, wind, or ice.

• Erosion is the process of planting trees to prevent soil loss.

• Erosion is the method of creating new landforms through volcanic activity.

• Erosion is the technique of using chemicals to break down rocks.

How is sedimentary rock formed?

• Sedimentary rock is formed from volcanic activity.

• Sedimentary rock is formed from smaller pieces of rock that settle at the bottom of lakes or oceans over time.

• Sedimentary rock is formed through the cooling of magma.

• Sedimentary rock is formed from the metamorphosis of igneous rock.

What is the role of pressure in rock formation?

• Pressure has no effect on rock formation.

• Pressure can cause changes in the structure and composition of rocks, leading to the formation of metamorphic rocks.

• Pressure only affects sedimentary rocks.

• Pressure is only relevant in the formation of igneous rocks.

What type of rock is gneiss?

• Igneous rock

• Sedimentary rock

• Metamorphic rock

• Volcanic rock

How are metamorphic rocks created?

• They are formed from the cooling of magma.

• They are created through heat and pressure as they move toward the Earth's core.

• They are formed by the accumulation of sediments over time.

• They are created by the erosion of existing rocks.

What is the significance of the rock cycle?

• It shows how rocks are continuously transformed and recycled in the Earth's crust.

• It explains the formation of mountains and valleys.

• It describes the process of erosion and sedimentation.

• It illustrates the impact of human activities on geological formations.
