Which statement accurately describes plate tectonics?

Which statement accurately describes plate tectonics?

Answer. Answer:The statement that accurately describes the aspects of plate tectonics that involve sub-duction and seafloor spreading is : Crust is created at the coastlines of continents.

Which statement explains why tectonic plates move?

The Earth’s internal heat drives convection currents in the asthenosphere, moving the plates past one another very slowly. Plates move only inches each year, carrying the continents and ocean basins with them as they drift.

What best describes Earth’s tectonic plates?

A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.

What is best explained by plate tectonics quizlet?

Which process is best explained by the Theory of Plate Tectonics? Tectonics plates divide the earth’s outer layer (lithosphere). Under the lithosphere is the asthenosphere where the differences in temperature and pressure cause the plates to move.

Where are the tectonic plates located?

In plate tectonics, Earth’s outermost layer, or lithosphere—made up of the crust and upper mantle—is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.

Why are there several tectonic plates What is the importance of studying tectonic plates?

Plate tectonics explains why and where earthquakes occur. This makes it possible to make predictions about earthquakes. Plate tectonics explains why and where mountains are formed. This makes Plate tectonics important to the study of geology.

What is the theory of plate tectonics called?

Plate tectonics is the theory that Earth’s outer shell is divided into large slabs of solid rock, called “plates,” that glide over Earth’s mantle, the rocky inner layer above Earth’s core. Earth’s solid outer layer, which includes the crust and the uppermost mantle, is called the lithosphere.

Who gave the theory of plate tectonics?

Alfred Wegener

What is the theory of plate tectonics quizlet?

plate tectonics. The theory of plate tectonics states that Earth’s surface is made of rigid slabs of rock, or plates, that move with respect to each other. tectonic plates. Earth’s tectonic plates are large pieces of lithosphere. These lithospheric plates fit together like the pieces of a giant jigsaw puzzle.

Who proposed the theory of plate tectonics quizlet?

What changes to Earth’s surface are explained by the theory of plate tectonics?

The plate tectonics theory explains that the plates are moving slowly along the Earth’s surface due to the convection currents in the mantle. Over time, the movement of plates results in the changes in the distribution of organisms, and the formation of volcanoes and mountain ranges, as well as earthquakes.

What are the two types of crust that tectonic plates are made of?

Today, tectonic activity is responsible for the formation (and destruction) of crustal materials. Earth’s crust is divided into two types: oceanic crust and continental crust. The transition zone between these two types of crust is sometimes called the Conrad discontinuity.

What are the 15 plates?

There may be scientific consensus as to whether such plates should be considered distinct portions of the crust; thus, new research could change this list.

  • African Plate.
  • Antarctic Plate.
  • Australian Plate.
  • Caribbean Plate.
  • Cocos Plate.
  • Eurasian Plate.
  • Nazca Plate.
  • North American Plate.
