A cave is a natural opening, usually, in mountains, that is large enough for human entry. I will write about three different types of caves: volcanic, glacier, and solution. Solution caves form in limestone and gypsum and are the most common type of caves in Texas. These are formed by

When the ice age ended it left behind many giant pieces of ice. These giant pieces of ice are known as glaciers. Most glaciers are found in Antarctica, Greenland, and North America. When summer rolls in the glaciers partly melt swelling the nearby rivers, streams, and lakes. When a glacier

Glaciers consist of ice crystals, air, water, and rock debris. The most important part of a glacier is the ice crystals. Glaciers can be found wherever it is suitable for snow to collect and survive. There are five types of glaciers: Ice Sheets, Ice Shelves, Ice Fields, Valley Glaciers, and

Earthquakes are the breaking and cracking of rocks inside the continental plates. They happen when stress builds up in the nearby area. Very few or no earthquakes occur when the plates move slowly but when they move quickly there is a higher possibility of earthquakes. When earthquakes occur they not

Between each tectonic plate, there are boundaries. All the tectonic plates are always moving towards, against, and away from each other. There are three possibilities when these boundaries collide, convergent boundaries, divergent boundaries, and transform boundaries. Convergent boundaries occur where two plates are pushing against each other forming mountains. One

Tectonic plates on top of the crust are giant plates of land that fit together like puzzle pieces. When two tectonic plates collide these events can happen: folding, faulting, dip slips, and strike slips. Folding is when two plates push against each other. This creates a massive bulge that sends

The Earth is split up into tectonic plates. The tectonic plates are like the skin of our planet. When two of these plates rub together there form volcanos or a violent earthquake occur. Some scientists believe that back in the day there was only one tectonic plate: Pangea. These scientists

The earth is made of 4 different layers that each has their own roles, the crust, the mantle, the outer core, and the inner core also known as the core. The crust of the earth is the top layer and is only about 60 km thick. The crust is the

Alluvial Fan: A large, fan-shaped pile of sediment forming at the base of narrow canyons. Alluvium: Gravel, silt, and clay deposited by streams. Arroyo: A dry desert gully. Dunes: Mounds of loose grains of sand piled up by the wind. Mesa: Broad flat-topped hill. Pediment: A gently sloping surface usually
