Is the layer of warm rock below the crust?

Is the layer of warm rock below the crust?

Question: 48) mantle is the cool, brittle, outer layer of Earth that includes the crust and uppermost 49) is the layer of warm rock below the crust and uppermost mantle that readily deforms and flows plastically, 50) The core is probably solidified.

What is the layer below the mantle called?

asthenosphere
The asthenosphere is the denser, weaker layer beneath the lithospheric mantle. It lies between about 100 kilometers (62 miles) and 410 kilometers (255 miles) beneath Earth’s surface. The temperature and pressure of the asthenosphere are so high that rocks soften and partly melt, becoming semi-molten.

What is the rock layer below the crust?

Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.

Is the layer of warm rock below the crust and uppermost mantle that readily deforms and flows plastically group of answer choices?

Lithosphere and asthenosphere are divisions based on mechanical properties. The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid. The asthenosphere is partially molten upper mantle material that behaves plastically and can flow.

Is the continental crust is thicker than oceanic crust?

The continental crust is also less dense than oceanic crust, although it is considerably thicker. As a consequence of the density difference, when active margins of continental crust meet oceanic crust in subduction zones, the oceanic crust is typically subducted back into the mantle.

Which layer of Earth is broken up into giant moving plates?

lithosphere
The lithosphere is divided into huge slabs called tectonic plates. The heat from the mantle makes the rocks at the bottom of lithosphere slightly soft. This causes the plates to move. The movement of these plates is known as plate tectonics.

Is the crust the thinnest layer?

Discuss with the whole class what the relative thicknesses of the layers are — that the inner core and outer core together form the thickest layer of the Earth and that the crust is by far the thinnest layer.

Which is thickest continental crust or oceanic crust?

It is thickest where prominent mountains exist. Oceanic crust is enriched in potassium, sodium, and silicon. Continental rocks are compositionally different than oceanic rocks. The dense core of Earth is thought to consist predominantly of ________.

What makes up the crust and the mantle?

The crust and mantle are solids; the inner core is thought to be solid. The mantle is composed mainly of metallic iron with small amounts of magnesium silicate minerals. What instrument is used to record earthquake vibrations?

Which is one of the following statements about the crust is not true?

Most of our knowledge about Earth’s interior comes from ________. Which one of the following statements about the crust is NOT true? It is the thinnest of the major subdivisions. It is thickest where prominent mountains exist. Oceanic crust is enriched in potassium, sodium, and silicon.

Where is the asthenosphere located in the Earth?

The asthenosphere is located ________. 38) S waves can travel through solid and liquid media. 39) The time between the first P-wave and S-wave arrivals is a measure of the distance from a receiving station to the epicenter of the earthquake.
