Q:

What are the large sections of the lithosphere called?

A:

Quick Answer

The large sections of the lithosphere are called tectonic plates. These plates are made up of the crust and upper mantle of the Earth, and they sit on top of the asthenosphere.

Full Answer

The tectonic plates are an important part of understanding the evolution of the appearance of the Earth through the years. In general, the plates measure about 100 to 200 kilometers thick. Underneath these tectonic plates, the hot asthenosphere moves and causes the movement of the plates above.

The movement of these plates causes the land masses to slowly move. Earth looks very different in modern times than millions of years ago. Continents collide and move apart as a result of the plates. The movement of two plates against one another causes earthquakes and forms mountains.

  • Q:

    How do earthquakes affect the lithosphere?

    A:

    Earthquakes are the result of brittle failure within the earth's lithosphere. Earthquakes cause energy to be released in an area of strain that is most often near a tectonic plate boundary.

  • Q:

    What temperature is the asthenosphere?

    A:

    The temperature of the asthenosphere begins at a little over 1,600 degrees Fahrenheit but does not rise above 6,700 degrees F. It lies beneath the lithosphere or crust of the earth and the more rigid part of the upper mantle.

  • Q:

    What is the upper mantle?

    A:

    The upper mantle forms part of the Earth's lithosphere, where earthquakes and volcanic activities frequently occur along plate boundaries. The upper mantle is separated from the crust by the Mohorivicic discontinuity, commonly referred to as "Moho," which derived its name from the Croatian scientist Andrija Mohorovicic.

  • Q:

    How do volcanoes affect the lithosphere?

    A:

    Volcanoes have a positive effect on the lithosphere; the buried materials, burnt trees and plants caused by the flow of lava help in fertilizing the soil, increasing its nutritive content. The Earth's lithosphere is made of different structures, such as rocks, plants and reefs, all of which are vulnerable to destruction during eruptions.
