Question

Answer 1

Answer:

Explanation:

There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers.

Answer 2

There are three kinds of rock:

• igneous rocks
• sedimentary rocks
• metamorphic rocks

Igneous: These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff.

Sedimentary: Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash.

Metamorphic: Some examples of metamorphic rocks are gneiss, slate, marble, schist, and quartzite.
