Rocks, Minerals, and Soils

What are the three main types of rocks?

• Volcanic, tectonic, and seismic

• Granite, marble, and limestone

• Crystal, quartz, and diamond

• Igneous, sedimentary, and metamorphic

How are igneous rocks formed?

• From the accumulation of dead plant and animal remains

• By the compression of layers of sediment

• Through the cooling and solidification of water

• From the solidification of molten rock material

Give an example of a sedimentary rock.

• Limestone

• Granite

• Obsidian

• Marble

What process is responsible for the formation of metamorphic rocks?

• Erosion

• Volcanism

• Metamorphism

• Weathering

What are the two main categories of minerals?

• Metallic minerals and non-metallic minerals

• Precious minerals and semi-precious minerals

• Organic minerals and inorganic minerals

• Silicate minerals and non-silicate minerals

How are minerals different from rocks?

• Minerals are the same as rocks

• Minerals are formed from rocks

• Rocks are made up of only one mineral

• Minerals are the building blocks of rocks, and rocks are composed of one or more minerals.

What are the three main components of soil?

• Sand, cement, and gravel

• Minerals, organic matter, and air/water

• Trees, grass, and flowers

• Rocks, insects, and bacteria

What is the difference between weathering and erosion?

• Weathering only occurs in deserts

• Weathering and erosion are the same process

• The difference between weathering and erosion is that weathering breaks down rocks and minerals, while erosion transports the broken materials to another location.

• Erosion only occurs in cold climates

How does soil texture affect plant growth?

• Soil texture affects plant growth by influencing water retention, aeration, and nutrient availability.

• Soil texture affects plant growth by altering the pH level of the soil

• Soil texture affects plant growth by changing the color of the plants

• Soil texture affects plant growth by attracting more insects to the area

What are the different layers of soil called?

• topsoil, subsoil, and bedrock

• rocky, sandy, clay

• upper soil, lower soil, deepest soil

• surface, middle, bottom
