What else can I help you with?
The oceanic crust is made up mostly of dense rock called what?
The oceanic crust is mostly made up of basalt, which is a dense volcanic rock that forms from the cooling of lava at the Earth's surface.
How is Earth's surface?
conduction
What is the percentage of oceanic crust on earth's surface?
Oceanic crust covers about 60% of the Earth's surface.
What is the eath made of?
The Earth is composed of several layers: the crust, mantle, and core. The crust is the outermost layer and is made up of solid rock. Beneath the crust is the mantle, which is mostly solid but can flow slowly over long periods of time. At the center of the Earth is the core, which is composed mostly of iron and nickel.
The opening in Earth's crust through which magma rises to the surface is known as the?
The opening in the earth crust which magma rise to the surface are Volcanoes
What elements form?
In the Earth's core iron makes up most of the mass. Everything else floats on the surface. The surface crust is mostly granite. The crust at the ocean bottom is mostly basalt.
Where is the center of the earth located?
The center of the Earth is located at a point beneath the Earth's surface, approximately 6,371 kilometers (3,959 miles) below the Earth's crust.
What is the distance from the earth to the center of the earthes crust?
The average distance from the surface of the Earth to the center of the Earth's crust is about 33 kilometers (20.5 miles). This distance can vary depending on location, as Earth's crust is not uniformly thick.
What layer of the earth is mostly solid with some large bodies of water?
The lithosphere, which includes the Earth's solid crust and upper mantle, is mostly solid. Large bodies of water, such as oceans and seas, are found on the Earth's surface, outside the lithosphere.
Why earth crust is solid?
Earth's crust is composed mostly of silicate minerals, which have high melting points. Surface temperatures are not nearly hot enough to melt these minerals.
What are the largest layer of earths surface composed mostly of silicon oxygen magnesium and iron?
The largest layer of Earth's surface that is composed mostly of silicon, oxygen, magnesium, and iron is the mantle. The mantle is located between the Earth's crust and core and makes up about 84% of Earth's volume.
What makes the crust unique?
What makes the crust unique is that it is the rigid, rocky outer surface of the Earth, composed mostly of thinner under the oceans.
Is the crust solid or liquid on the Earth's surface?
The crust on Earth's surface is solid.
Temperature increases from the center of the earth towards its surface true or false?
False. The temperature increases from the surface of the Earth towards its center. This is due to the heat generated from the Earth's core and the radioactive decay of elements in the Earth's mantle and crust.
Largest layer of earth's surface's composed mostly of silicon oxygen magnesium and iron?
Oceanic crust.
Is the earth mostly made out of silicates?
Yes, the Earth's crust is primarily composed of silicate minerals, which make up the majority of the planet's surface. Silicates are minerals containing silicon and oxygen, forming the most abundant group of minerals in the Earth's crust.
What is another name for the Earth's surface?
Another name for the Earth's surface is:THe crust
