What best describes the Earth’s mantle?

The mantle is the mostly-solid bulk of Earth’s interior. The mantle lies between Earth’s dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth’s total volume.

Which best describes the mantle quizlet?

Which statement BEST describes the Earth’s mantle? The mantle is the 3rd hottest layer and is the 3rd in terms of the amount of pressure present. It is thickest layer.

What best describes Earth’s crust and mantle?

The crust is made of solid rocks and minerals. 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.

What is in Earth’s mantle?

In terms of its constituent elements, the mantle is made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. There’s also iron, aluminum, calcium, sodium, and potassium. These elements are all bound together in the form of silicate rocks, all of which take the form of oxides.

Which statement best describes the relationship between Earth’s mantle and core?

Q. Which statement BEST describes the relationship between Earth’s mantle and core? The mantle lies just below the core. The mantle and core are made up of hard, solid rock.

What’s inside the Earth’s mantle convection?

Mantle convection is the very slow creeping motion of Earth’s solid silicate mantle caused by convection currents carrying heat from the interior to the planet’s surface. The Earth’s surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.

Which best explains mantle convection?

Which best explains mantle convection? Mantle convection is the very slow creeping motion of Earth’s solid silicate mantle caused by convection currents carrying heat from the interior to the planet’s surface.

How does mantle convection Brainly?

The convection in the mantle occurs when the heat in the mantle layers is passed to the surface. This effect is achieved by fluid-like motion of the rocks. The areas that are hotter rise in an upward direction causing a convection effect.

What are the main features of the mantle and the core?

The mantle consists of solid or semi-solid iron-magnesium silicate rocks, not molten rocks. It is divided into inner and outer zones, and these represent changes in the mineral composition. Core: The core is beneath the mantle. It is the deepest and hottest layer of the Earth.

What are features of mantle?

THE MANTLE IS ONE OF THE THREE MAIN LAYERS OF THE EARTH.IT LIES BETWEEN THE INNERMOST LAYER, THE CORE AND THE THIN OUTERMOST LAYER , CRUST. THE MANTLE CONSISTS OF HOT,DENSE SEMISOLID ROCK AND IS ABOUT 2,900 KILOMETERS(1,800 MILES) THICK. MOVEMENT IN MANTLE CAUSES VOLCANIC ERUPTIONS AND EARTHQUAKES.

What are three amazing facts about the Earth’s mantle?

Five facts about the mantle include:

• The mantle makes up 84% of Earth’s volume.
• The mantle extends from 35-2980 kilometers below Earth’s surface.
• The mantle is mostly solid rock. …
• The mantle ranges in temperatures from 200 to 4000 degrees Celsius.
• Convection currents in the mantle drive plate tectonics.

What are the characteristics of the upper mantle?

Its chemical composition is very similar to the crust. One difference is that rocks and minerals of the mantle tend to have more magnesium and less silicon and aluminum than the crust. The first four most abundant elements in the upper mantle are oxygen, magnesium, silicon, and iron.

What are the characteristics of the lower mantle?

The lower mantle is the liquid inner layer of the earth from 400 to 1,800 miles below the surface. The lower mantle has temperatures over 7,000 degrees Fahrenheit and pressures up to 1.3 million times that of the surface near the outer core.

What is Earth’s upper mantle?

From Wikipedia, the free encyclopedia. The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi).

Why is the mantle a solid?

The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases.

Is Earth’s mantle lava?

Much of the planet’s mantle consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth’s surface, it is called lava. Like solid rock, magma is a mixture of minerals.

Why is the mantle liquid?

The mantle in liquid state due to its pressure and high temperatures. Explanation: Earth’s mantle is located under the earth the crust of the planet and is entirely made of the liquid magma and in the form of solid rock.

What is important about the mantle?

The mantle

Earth’s mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. Heat liberated by the core is transferred into the mantle where most of it (> 90%) is convected through the mantle to the base of the lithosphere.

Is the Earth’s mantle real?

The Earth’s mantle is a layer of silicate rock between the crust and the outer core. Its mass of 4.01 × 10²⁴ kg is 67% the mass of the Earth. It has a thickness of 2,900 kilometres (1,800 mi) making up about 84% of Earth’s volume. It is predominantly solid but in geological time it behaves as a viscous fluid.

What does Earth’s mantle look like?

In grade-school science textbooks, Earth’s mantle is usually shown in a yellow-to-orange gradient, a nebulously defined layer between the crust and the core. To geologists, the mantle is much more than that. It’s a region somewhere between the cold crust and the bright heat of the core.

Where can you see Earth’s mantle?

Canada’s remote Gros Morne National Park is one of the few places where you can see the Earth’s mantle.

• Gros Morne National Park is a Unesco-designated wilderness. …
• The Tablelands is one of the few places where you can glimpse the Earth’s mantle. …
• The mantle has been visible for the last 12,000 years.
