Exploring Rocks and Resources Quiz

Which type of rock is formed from molten rock?

• Sedimentary

• Igneous

• Metamorphic

• Fossilized

Answer explanation

Igneous rocks are formed from the cooling and solidification of molten rock, known as magma or lava. This distinguishes them from sedimentary and metamorphic rocks, which form through different processes.

What is the term for the movement of rock by gravity, wind, water, and ice?

• Weathering

• Erosion

• Melting

• Freezing

Answer explanation

The term for the movement of rock by gravity, wind, water, and ice is 'Erosion'. This process involves the transportation of soil and rock materials from one location to another, distinguishing it from weathering, which is the breakdown of rocks.

Which mineral property describes how a mineral reflects light?

• Hardness

• Color

• Luster

• Streak

Answer explanation

Luster describes how a mineral reflects light, indicating its shine or dullness. It is a key property used to identify minerals, distinguishing them from others based on their appearance.

What type of rock is formed from heat and pressure?

• Igneous

• Sedimentary

• Metamorphic

• Volcanic

Answer explanation

Metamorphic rocks are formed when existing rocks are subjected to high heat and pressure, causing physical and chemical changes. This distinguishes them from igneous and sedimentary rocks, which form through different processes.

Which process involves the breaking down of rock by wind, water, ice, temperature change, and plants?

• Erosion

• Weathering

• Sedimentation

• Fossilization

Answer explanation

Weathering is the process that breaks down rocks through natural forces like wind, water, ice, temperature changes, and biological activity from plants. Erosion, on the other hand, involves the movement of these broken materials.

Which mineral property is tested by scratching the mineral with a tool?

• Cleavage

• Hardness

• Luster

• Streak

Answer explanation

The property tested by scratching a mineral with a tool is its hardness. This test determines how resistant the mineral is to being scratched, which is a key characteristic in mineral identification.

Which of the following is a nonrenewable resource?

• Wind energy

• Water

• Oil

• Solar energy

Answer explanation

Oil is a nonrenewable resource because it is formed over millions of years and cannot be replenished on a human timescale. In contrast, wind energy, water, and solar energy are renewable resources.

Which type of rock is made from pieces of other rocks and fossilized organisms?

• Igneous

• Sedimentary

• Metamorphic

• Crystalline

Answer explanation

Sedimentary rocks are formed from the accumulation and cementation of fragments of other rocks and organic materials, including fossilized organisms. This distinguishes them from igneous and metamorphic rocks.

Which resource is commonly used in the production of glass and electronics?

• Phosphate

• Limestone

• Silicon

• Water

Answer explanation

Silicon is a key resource in the production of glass and electronics due to its properties as a semiconductor and its ability to form silicates, which are essential in glassmaking.
