Which layer of the earth’s interior listed below is also the full equivalent of a tectonic plate?

Which layer listed below can also be considered a tectonic plate?

Tectonic plates are pieces of Earth’s crust and uppermost mantle , together referred to as the lithosphere . The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium).

Where is the thickest part of a tectonic plate?


What layers of the earth are involved in plate tectonics?

The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere . The layer below the rigid lithosphere is a zone of asphalt-like consistancy called the Asthenosphere . The asthenosphere is the part of the mantle that flows and moves the plates of the Earth.

Is the mesosphere hotter than the asthenosphere?

The Mesosphere is hotter than the Asthenosphere and as a result flows faster than the Asthenosphere .

What does the SP interval represent exactly?

Where do earthquake waves originate from? Which type of wave below can travel through solids and liquids and is similar to a sound wave? What does the S-P interval represent exactly ? The correct answer is : It is the time interval between the arrival of the P-wave and the arrival of the S-wave at a seismic station.

What tectonic plate is Japan in?

Japan sits on or near the boundary of four tectonic plates: the Pacific , North American, Eurasian and Filipino plates. * These massive slabs of earth’s crust are endlessly creeping, slipping, locking up and then jolting again.

How thick are the tectonic plates?

What causes tectonic plates to move?

The heat from radioactive processes within the planet’s interior causes the plates to move , sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift .

How deep are the tectonic plates?

The crust beneath the continents, however, is much more variable in thickness, averaging about 30 kilometers (18.6 miles); under large mountain ranges it can extend to depths of up to 100 kilometers (62.1 miles). The San Andreas fault is the border between two tectonic plates —the North American Plate and Pacific Plate .

What are the 7 layers of earth?

They are, from deepest to shallowest, the inner core , the outer core , the mantle and the crust . Except for the crust , no one has ever explored these layers in person.

How thick is Earth’s crust?

The crust thickness averages about 18 miles (30 kilometers) under the continents, but is only about 3 miles (5 kilometers) under the oceans. It is light and brittle and can break. In fact it’s fractured into more than a dozen major plates and several minor ones.

Is the asthenosphere in the crust?

Asthenosphere , zone of Earth’s mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere.

Why is the mesosphere so important?

The mesosphere is very important for earth’s protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth’s surface. The mesosphere is the coldest atmospheric layer surrounding the earth. It becomes cold enough to freeze water vapour in its atmosphere into ice clouds.

What is the temperature of the mesosphere inside the Earth?

Mesosphere: The mesosphere is the coldest layer, dropping to as low as -184 degrees Fahrenheit . The temperature decreases with height in this layer. Most meteors vaporize in the mesosphere.

Which layer is between the mesosphere and the inner core?

Asthenosphere Crust Lithosphere Outer Core .
