Structure of the Earth and Rock Cycle

What is the outermost layer of the Earth called?

• atmosphere

• crust

• core

• mantle

What is the composition of the Earth's mantle?

• Carbonate rocks rich in calcium and potassium

• Silicate rocks rich in magnesium and iron

• Metamorphic rocks rich in aluminum and silicon

• Igneous rocks rich in sodium and chlorine

Name the three types of rocks.

• Granite, limestone, and marble

• Igneous, sedimentary, and metamorphic

• Volcanic, sedimentary, and crystalline

• Magma, shale, and slate

What are the stages of the rock cycle?

• Granite rocks, limestone rocks, and marble rocks

• Igneous rocks, sedimentary rocks, and metamorphic rocks

• Volcanic rocks, sedimentary rocks, and metamorphic rocks

• Magma rocks, erosion rocks, and pressure rocks

What are the layers of the Earth's core?

• Crust and upper mantle

• Outer core and inner core

• Mantle and crust

• Upper core and lower core

How are sedimentary rocks formed?

• Through the process of weathering, erosion, deposition, compaction, and cementation.

• Through volcanic eruptions and cooling of magma

• By the process of evaporation and crystallization

• Through the movement of tectonic plates and folding of layers

What are fossils and how are they formed?

• Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. They are formed when the remains are buried in sediment and undergo a process called fossilization.

• Fossils are formed when the remains are exposed to extreme heat and pressure deep within the Earth's crust.

• Fossils are the preserved remains of animals, plants, and other organisms from the recent past.

• Fossils are the result of recent animal remains being buried in sediment and undergoing a process called fossilization.

The magnetic field of the earth are placed at ....

• continental crust

• inner core

• upper core

• outer core

Name some structures found on Earth's surface.

• Buildings, lakes, swamps, tundra

• Skyscrapers, deserts, oceans, forests

• Mountains, rivers, valleys, plateaus

• Bridges, canyons, islands, glaciers

Differentiate between intrusive and extrusive igneous rocks.

• Intrusive igneous rocks form beneath the Earth's surface, while extrusive igneous rocks form on the Earth's surface.

• Intrusive igneous rocks are fine-grained, while extrusive igneous rocks are coarse-grained.

• Intrusive igneous rocks are formed by volcanic activity, while extrusive igneous rocks are formed by tectonic forces.

• Intrusive igneous rocks form on the Earth's surface, while extrusive igneous rocks form beneath the Earth's surface.
