Exploring Rocks and Materials

What is the process of formation for igneous rocks?

• Igneous rocks form from the crystallization of minerals in water.

• Igneous rocks are formed by the cooling and solidification of magma or lava.

• Igneous rocks are formed by the erosion of sediment.

• Igneous rocks are created through the compression of organic materials.

Name two types of igneous rocks.

• Granite and basalt

• Limestone and sandstone

• Intrusive and extrusive

• Sedimentary and metamorphic

What are the main types of metamorphic rocks?

• Igneous and sedimentary rocks

• Foliated and non-foliated rocks

• Metasomatic and hydrothermal rocks

• Granite and basalt rocks

How does heat and pressure affect rocks in metamorphism?

• Metamorphism occurs only at low temperatures and pressures.

• Heat and pressure only change the color of rocks.

• Heat and pressure cause physical and chemical changes in rocks, leading to the formation of metamorphic rocks.

• Rocks remain unchanged under heat and pressure.

Describe the rock cycle in your own words.

• The rock cycle is a process that only involves sedimentary rocks.

• The rock cycle is a linear process that does not involve any transformations.

• The rock cycle is the process of rocks changing from one type to another through various geological processes.

• The rock cycle describes how rocks are formed from minerals without any changes.

What is the difference between intrusive and extrusive igneous rocks?

• Intrusive rocks have larger crystals due to slow cooling, while extrusive rocks have smaller crystals due to rapid cooling.

• Intrusive rocks are formed from lava on the surface.

• Intrusive rocks cool rapidly and are found on the surface.

• Extrusive rocks have larger crystals due to slow cooling.

List three uses of igneous rocks in construction.

• Insulation material for homes

• 1. Aggregate in concrete 2. Dimension stone for buildings 3. Road construction

• Fertilizer for agriculture

• Water filtration systems

What are foliated and non-foliated metamorphic rocks?

• Foliated metamorphic rocks have a layered appearance, while non-foliated metamorphic rocks do not.

• Foliated rocks are always dark in color, while non-foliated rocks are light.

• Non-foliated metamorphic rocks have a layered appearance, while foliated rocks do not.

• Foliated metamorphic rocks are formed from igneous rocks, while non-foliated are from sedimentary rocks.

How do synthetic materials differ from natural materials?

• Natural materials are always synthetic.

• Synthetic materials are always biodegradable.

• Synthetic materials are derived from plants and animals.

• Synthetic materials are man-made, while natural materials come from nature.

Give an example of a synthetic material found in nature.

• Rubber

• Metal

• Glass

• Plastic
