Q How do igneous rocks form? Give examples.A: They form from the cooling of magma after volcanic eruption. Outer lava becomes
basalt and inner lava becomes granite.

Q How do metamorphic rocks form? Give examples.A: They are either sedimentary or igneous which are changed to another form from
heat and pressure inside the earth. Lime stone become marble and clay become slate.

Q What are non-porous or impermeable rocks?A: Rocks that do not absorb water, are called non-porous rocks.
Example marble and granite.

Q What are fossils?A: Fossils are remains of animals that are preserved in sedimentary rocks.
![Page 25: Rocks. Q What do we get from the earth? A: We get rocks, metals, natural gases, coal and oils from the earth](https://reader035.vdocuments.mx/reader035/viewer/2022062720/56649f125503460f94c262de/html5/thumbnails/25.jpg)
Q What does the rock cycle show?A: Rock cycle shows how igneous rock forms sedimentary or metamorphic rock. Which
eventually melt and become igneous rock again.
![Page 26: Rocks. Q What do we get from the earth? A: We get rocks, metals, natural gases, coal and oils from the earth](https://reader035.vdocuments.mx/reader035/viewer/2022062720/56649f125503460f94c262de/html5/thumbnails/26.jpg)
Q Show rock cycle.
