Why does the elevation of the seafloor decrease from the mid ocean ridge to the abyssal plain quizlet?

Why does the elevation of the seafloor decrease from the mid-ocean ridge to the abyssal plain? The oceanic lithosphere cools and becomes denser. … Spreading along the Atlantic ridge added seafloor to plates on both sides. Subduction has consumed large areas of old oceanic crust in the Pacific.

Is the ocean floor topographically flat?

The ocean floor is topographically flat while the continents show significant variations in elevation.

Which one of the following describes the lithosphere?

Lithosphere is the rigid rocky outer layer of the earth consisting of the crust and the solid outermost layer of the upper mantle. It extends to a depth of about 100 km.

Which of the following best describes the lithosphere and asthenosphere?

Q. Which of these describes the lithosphere and the asthenosphere? The lithosphere is rigid and immovable and the asthenosphere is hot and flowing.

Which of the following is the best description of 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 statement best explains why Earth’s lithosphere is broken into tectonic plates?

Which statement best explains why Earth’s lithosphere is broken into tectonic plates? The brittle lithosphere cracks under pressure from the moving asthenosphere. The lithosphere cracks and deforms under the weight of the continents.

Which best describes the crust of the earth?

Earth’s Crust. “Crust” describes the outermost shell of a terrestrial planet. Earth’s crust is generally divided into older thicker continental crust and younger denser oceanic crust. … Beneath the crust is the mantle which is also mostly solid rocks and minerals but punctuated by malleable areas of semi-solid magma.

Why does the seafloor decrease in elevation with distance from the Mid-ocean?

Mid-ocean ridges and seafloor spreading can also influence sea levels. As oceanic crust moves away from the shallow mid-ocean ridges it cools and sinks as it becomes more dense. This increases the volume of the ocean basin and decreases the sea level.

What occurs at mid-ocean ridges quizlet geology?

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

Why is the mid-ocean ridge in the center of the ocean?

Mid-ocean ridges are geologically important because they occur along the kind of plate boundary where new ocean floor is created as the plates spread apart. Thus the mid-ocean ridge is also known as a “spreading center” or a “divergent plate boundary.” The plates spread apart at rates of 1 cm to 20 cm per year.

What ocean floor features are part of the continental crust?

A continental margin is the outer edge of continental crust abutting oceanic crust under coastal waters. It is one of the three major zones of the ocean floor the other two being deep-ocean basins and mid-ocean ridges. The continental shelf is the relatively shallow water area found in proximity to continents.

What are the features of ocean basins describe each?

A number of major features of the basins depart from this average—for example the mountainous ocean ridges deep-sea trenches and jagged linear fracture zones. Other significant features of the ocean floor include aseismic ridges abyssal hills and seamounts and guyots.

What is topography of the ocean floor?

The term “topography” implies the study of numerous landforms that exist on or below the earth. Ocean floor topography refers to the different forms in which the ocean floor bottom can exist. You may perceive the ocean floor to be flat and sandy like the beach but the truth is there are many different surfaces.

What are the 3 components of lithosphere?

Lithosphere The solid part of the earth. It consists of three main layers: crust mantle and core.

Which part of the earth crust is known as lithosphere?

The outermost layer called the crust is solid too. Together these solid parts are called the lithosphere. Earth’s crust is made up of hard rocks. It is the only part of the Earth that humans see.

How is lithosphere formed Wikipedia?

When a continental plate comes together with an oceanic plate at a subduction zones the oceanic lithosphere always sinks beneath the continental. New oceanic lithosphere is constantly being produced at mid-ocean ridges and is recycled back to the mantle at subduction zones.

Which of the following describes the physical difference between the lithosphere and asthenosphere?

The lithosphere is the brittle crust and uppermost mantle. The asthenosphere is a solid but it can flow like toothpaste. The lithosphere rests on the asthenosphere.

In which of the following ways are the earth’s lithosphere and asthenosphere similar?

In which of the following ways are the Earth’s lithosphere and asthenosphere similar? Both layers are made mostly of solid rock. … The lithosphere is a rigid layer made of Earth’s entire crust and the very top part of Earth’s mantle. This rigid layer is divided into several large pieces or plates.

How is lithosphere formed Class 9?

Due to the cold temperature of space the surface layer of earth cooled off quickly. … And forms solidified “outer layer of the earth” called lithosphere. Differentiation of magma makes two types of “lithosphere oceanic” and continental which is characterized in the continents by “basalt in oceans” and granite.

What is the best description of the Earth’s lithosphere?

The lithosphere is the solid outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.

Which description best represents heat flow and movement in Earth’s mantle?

When magma is heated it becomes less dense and rises. When magma is cooled it becomes more dense and sinks. Which description best represents heat flow and movement in Earth’s mantle? the core because strong pressure and temperature create both liquid and solid parts.

Which of the following describes interior of the Earth?

The dense hot inner core (yellow) the molten outer core (orange) the mantle (red) and the thin crust (brown) which supports all life in the known universe. Earth’s interior is generally divided into three major layers: the crust the mantle and the core.

What does the plate tectonic theory explain about the lithosphere of the earth?

The theory of plate tectonics states that the Earth’s solid outer crust the lithosphere is separated into plates that move over the asthenosphere the molten upper portion of the mantle. Oceanic and continental plates come together spread apart and interact at boundaries all over the planet.

What is the lithosphere and tectonic plate?

The lithosphere which is the rigid outermost shell of a planet (the crust and upper mantle) is broken into tectonic plates. … Tectonic plates are composed of the oceanic lithosphere and the thicker continental lithosphere each topped by its own kind of crust.

What is the scientific basis for dividing the lithosphere into plates?

The basis of the scientist in dividing the Earth’s lithosphere into several segments called plates is the distribution of earthquake epicenters location of volcanoes and formation of mountain ranges. All of this geological features that are formed because of plate movement.

Which statement best describes the crust Quizizz?

Which best describes Earth’s crust? It is the thickest layer of Earth. It is composed of several continental plates.

Which of the following best describe continental crust?

The continental crust is the layer of granitic sedimentary and metamorphic rocks which form the continents and the areas of shallow seabed close to their shores known as continental shelves. It is less dense than the material of the Earth’s mantle and thus “floats” on top of it.
