Crust, the Moho, and the upper mantle

The crust is thickest at the mountains and thinnest under the oceans

The moho is an imaginary line or boundary where the rocks in the Earth's crust change into mantle Rock

Moho

Sedimentary rock is formed when sediment is deposited in layers and hardens into rock

Metamorphic rock is formed when pressure and heat change the structure of existing igneous or sedimentary rock

Magma is molten Subterranean Rock

Pumice

Pumice is an igneous rock that can float in water it is formed when lava erupts into the atmosphere and cools rapidly trapping bubbles of gas inside the Rock

Obsidian is a dense, glass like, extremely hard igneous rock that forms when lava comes into contact with cold water or ice and cools rapidly

Subterranean forces

Sandstone is a sedimentary rock that consists of grains of sand that have been cemented together

Shale was once muddy clay that hardens into sedimentary rock. Many fossils can be found in abundance in shale

A Butte is a flat-topped landform with steep sides that is taller than it is wide

A conglomerate is sedimentary rock containing Pebbles or Stones cemented together in one stratum

Gneiss is igneous metamorphic rock with sparkling crystals that is formed when Granite is heated almost to its melting point

Marble rock is sedimentary metamorphic rock formed from Limestone that is useful because it is hard and resist erosion

A Mesa is a flat-topped landform with steep sides that is wider than it is tall

Mica is a common type of schist that can be separated into thin glass like sheets

Mount Everest

A plateau is a large flat topped area of land that rises above the land next to it on at least one side

A schist is a variety of metamorphic rock that can form from either sedimentary or igneous rock

Stalactites are limestone formations hanging from cave ceilings remember that stalactites stick-tight

Stalagmites are limestone formations Rising upward from cave floors

A plain

Headwaters

A ravine

A narrow Valley with high steep sides

Tributary

Sediment deposited at the mouth of a river forming a triangle shaped Rich agricultural area

Geysers and hotsprings are formed when underground water is heated by magma and the heated water makes its way to the surface of the Earth's crust
