Seismic Waves

Seismic waves are waves of energy that travel through the earth, for example as a result of an earthquakes explosion, or some other process that imparts low-frequency acoustic energy.Earthquakes create various types of waves with different velocities; when reaching seismic observatories, their different travel time enables the scientists to locate the epicenter.Seismic waves are divided into two types: Body waves and surface waves. Body waves include P and S waves, and these are the two types of waves that are used to determine the internal structure of the Earth

Batholith

A batholith is a pluton that can range from hundreds to thousand of cubic kilometers across and 10-30 km beneath the earth's surface. Batholith means deep or depth stone is greek. The batholith located in California is The Sierra Nevadas.Batholiths are almost always made mostly of felsic or intermediate rock-types, such as grantie quartz monzonite, or diorite.

Starta Volcanoes vs Shield Volcanoes

A shield volcano is a type of volcano built almost entirely of fluidlava flows. They are named so because of their large size and low profile, resembling a warrior's shield. This is caused by the highly fluid lava they erupt, which travel farther than those erupted from more explosive volcanoes
A stratovolcano, also known as a composite volcano, is a tall, concial built up by many layers (strata) of hardened lava, tephra, pumica, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic,explosive eruptions

The Loop Current is a warm ocean current in the Gulf of Mexico that flows northward between Cuba and the Yucatan peninsula, moves north into the Gulf of Mexico, loops west and south before exiting to the east through the Florida Straitsand joining the Gulf Streams.Some oil from the Gull of Mexico spills is most likely to be dragged into strong currents  that's hug Florida coastal areas.Once in the Loop Current, oil can travel south and enter the Gulf Stream, a powerful ocean conveyor belt that carries warm water up the eastern seaboard.The current travels about 50 to 100 miles a day.

plate tectonic

The tectonic plates are composed of two types of lithospere: thicker continental and thin oceanic.Tectonic plates are able to move because the Earth's lithosphere has a higher strength and lower density than the underlying asthenosphere.

Oceans

Most of the ocean is as dark as night, with temperatures either just above freezing or, in a few places, hotter than humans can handle.The ocean covers 71 percent of the Earth's surface.  The ocean supports the life of nearly 50 percent of all species on Earth.

water cycle

A water cycle diagram.
The water cycle has for different stages: condensation evaporation collection and precipitation. the earths water cover more then 3/4  of the earths surface. 97% to be exact. only 3% of the water on the earths surface is fresh water all the rest is salt water.

Early Solar System


In the early solar system, 4.6 billion years ago comets and asteriods were created along with the rest of our solar system. at this point in time the earths atmosphere was much different from todays.
