Quiz Questions Over Rocks And Minerals

1. What are the names of the 3 types of rocks?

Pebbles, boulders, mountains

Sand, gravel, clay

Igneous, sedimentary, metamorphic

Diamonds, rubies, pearls

None of the above

The correct answer is igneous, sedimentary, metamorphic. These are the three main types of rocks based on their formation processes. Igneous rocks are formed from cooled and solidified magma or lava. Sedimentary rocks are formed from the accumulation and compression of sediments over time. Metamorphic rocks are formed from the transformation of existing rocks due to high heat and pressure. Pebbles, boulders, mountains, sand, gravel, clay, diamonds, rubies, and pearls are not types of rocks, but rather specific examples or components of rocks.

2. What are the names of the layers of the earth?

Crust, mantel, outer core, inner core

Hot, hotter, hottest

Sand, gravel, iron, nickel

Land, water, air, atmosphere, landforms

None of he above

The correct answer is crust, mantle, outer core, inner core. These are the names of the layers of the Earth. The crust is the outermost layer, followed by the mantle, which is a thick layer of hot, solid rock. Below the mantle is the outer core, which is made of liquid iron and nickel. Finally, at the center of the Earth is the inner core, which is a solid ball of iron and nickel.

3. What is the molten liquid rock called inside of a volcano?

Lava

Magma

Ash

Igneous

None of the above

Magma is the molten liquid rock found inside of a volcano. When a volcano erupts, the magma is expelled from the Earth's interior and becomes known as lava once it reaches the surface. Ash is the fragmented material that is ejected during a volcanic eruption, while igneous refers to the type of rock formed from solidified magma or lava. Therefore, the correct answer is magma.

Ash is the fragmented material that is ejected during a volcanic eruption, while igneous refers to the type of rock formed from solidified magma or lava. Therefore, the correct answer is magma.

4. Which rock type has fossils inbedded inside?

Igneous

Sedimentary

Metamorphic

Boulders

All of the above

Sedimentary rocks are formed from the accumulation and compression of sediment over time. Fossils are commonly found in sedimentary rocks because they are formed by the accumulation of organic remains such as plants, animals, and other organisms. As these remains become buried and compacted, they can leave behind imprints or actual remains that become preserved in the sedimentary rock. Therefore, sedimentary rocks are the type of rock that most commonly contains fossils.

5. The rock cycle is where

The earth moves in circles to move rocks from inside the earth to outside the crust

The water is pushed up from the inside the earth

Rocks ride a bicycle

Rocks have heat, pressure, or both placed on them and rocks change

None of the above

The rock cycle refers to the continuous process of rocks being subjected to heat, pressure, or both, causing them to undergo changes in their composition, structure, and form. This process involves various geological processes such as melting, solidification, weathering, erosion, and sedimentation. Through these processes, rocks can be transformed into different types, such as igneous, sedimentary, and metamorphic rocks.
