Describes the theory of plate tectonics and how the theory has changed the way geologists think about the Earth. Details major plates and how the theory helps predicts earthquakes. Plate tectonics, or plate movements, have changed the way geologists think about the Earth.

Long ago, people thought that the Earth never changed. Those people thought that it was exactly like it has always been. Overtime, scientists realized that fossils were found in places where they should not be. That made them begin to wonder. In the rocks at the top of the Himalaya Mountains, scientists found many fossils.

The Plate Tectonics Theory - Essay

Sand and gravel in long rows showed that the middle of the Sahara Desert was once covered in a glacier. In Antarctica, fossils of trees, ferns, and plant-eating dinosaurs were found. Antarctica was most likely near the equator millions of years ago. After a long time, it might've broken apart from Pangaea and moved south.

This also explains the evidence of glaciers in the Sahara Desert. The Earth's surface is broken into many different sections, called plates.

Essay title: The Plate Tectonics Theory

When the plates force a high amount of pressure on each other, its causes earthquakes, volcanoes to erupt, and the formation of mountains. The area where two plates meet is called plate boundaries. Plate tectonics is a combination of two ideas, sea-floor spreading and continental drift.

The creation of new oceanic crust at mid-ocean ridges is called sea-floor spreading. Inspreading plate margins became part of the theory of plate tectonics.

Plate tectonic theory essay

This theory explains not only about how ancient crust is destroyed along destructive plate margins, but it also explains how new ocean floor is created.

Sea-floor spreading is also the movement of crust away from the mid-ocean ridges. When continents over Earth's surface change position, it is called continental drift.Read this Science Essay and over 88, other research documents.

For millions of years, tectonic plates have been determinate of /5(1). Plate Tectonics is a scientific theory which study how the Earth’s plates are driven and shaped by geological forces to keep them in constant movement.

The theory explains the present-day tectonic behavior of the Earth, particularly the global distribution of mountain building, earthquake activity.

These massive plates move underneath the surfaces of the oceans and the continents, producing earthquakes, volcanoes and uplifts/5(1). Throughout this essay the theory of plate tectonics will be discussed extensively with key references to the volcanic and seismic events and how they are a direct result of the movement of tectonic plates.

The Plate Tectonics Theory Essay. Plate tectonics is the science and study of causes and relative motions of earth’s lithosphere plates - The Plate Tectonics Theory Essay introduction. This theory proposes that earth’s outer layer is made up of plates which have moved throughout earth’s history.

This paper will discuss the composition, movement and history of tectonic plates, the theory of plate tectonics and its history, and tectonic plates affect the surface of the earth today and will continue to do so in the future.
