Q:

What is a batholith?

A:

The term batholith refers to a large body of igneous rock that is formed below the surface of the earth because of the intrusion and solidification of magma. A batholith usually consists of coarse-grained rocks, such as granite or granodiorite.

This body of igneous rock is irregularly shaped, and its side walls are steeply inclined against its host rock. It was once believed that batholiths extend to unknown depths, but recent studies have found that many batholiths are 10 to 15 km, or 6 to 9 miles, thick. One popular batholith is found in the Sierra Nevada range located in California.

  • Q:

    Where does upwelling occur?

    A:

    Upwelling occurs in any location where the continuous action of wind against the ocean surface pushes the top layer of water away, causing deeper water to rise to the surface. Coastal upwelling is common, and most coastal regions with rich fisheries are locations with frequent upwelling.

  • Q:

    How do geysers form?

    A:

    A geyser is essentially an underground hot spring that, owing to pressure exerted against its constricted plumbing toward the surface of the ground, issues a stream of steam and boiling water from time to time. The term "geyser" is derived from the Icelandic word "geysir," which means to rush forth. A geyser stops erupting once its reservoir is empty, or the water below the surface cools.

  • Q:

    How did oceans form?

    A:

    Nearly 3.8 billion years ago, temperatures on Earth cooled below 100 degrees Celsius for the first time, allowing water, which existed on the planet in gaseous form, to condense into rain and collect on the planet's surface, according to the American Museum of Natural History. This water collected in low-lying areas, eventually becoming a primitive ocean.
