Which most accurately describes the Earth's crust quizlet?
Which statement BEST describes the Earth's crust? The crust is the coolest layer with the least amount of pressure.
Which most accurately describes the 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. The dynamic geology of Earth's crust is informed by plate tectonics. “Crust” describes the outermost shell of a terrestrial planet.Jul 15, 2022
What is the Earth's crust made of?
The Earth's crust comprises about 95% igneous and metamorphic rocks, 4% shale, 0.75% sandstone, and 0.25% limestone. Oxygen, silicon, aluminum, and iron account for 88.1% of the mass of the Earth's crust, while another 90 elements make up the remaining 11.9%.Dec 14, 2021
What is the Earth's crust quizlet?
Crust. In geology, the crust is the outermost solid shell of a rocky planet or natural satellite, which is chemically distinct from the underlying mantle. Mantle. The interior of Earth, similar to the other terrestrial planets, is chemically divided into layers.
What is the crust of the earth?
“Crust” describes the outermost shell of a terrestrial planet. Our planet's thin, 40-kilometer (25-mile) deep crust—just 1% of Earth's mass—contains all known life in the universe. Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals.Jul 15, 2022
What is the Earth's crust and what is it made of?
Earth's Crust Elements
The crust is a rigid surface containing both the oceans and landmasses. Most elements are found in only trace amounts within the Earth's crust, but several are abundant. The Earth's crust comprises about 95% igneous and metamorphic rocks, 4% shale, 0.75% sandstone, and 0.25% limestone.Dec 14, 2021
What is the crust called?
Earth's crust is divided into two types: oceanic crust and continental crust. The transition zone between these two types of crust is sometimes called the Conrad discontinuity. Silicates (mostly compounds made of silicon and oxygen) are the most abundant rocks and minerals in both oceanic and continental crust.
What is the Earth's crust made of quizlet?
The Earth's crust is the outermost and thinnest layer of the earth. It is made of solid rock and soil.
What is the Earth's crust Short answer?
Earth's crust is Earth's thin outer shell of rock, referring to less than 1% of Earth's radius and volume. It is the top component of the lithosphere, a division of Earth's layers that includes the crust and the upper part of the mantle.
What is the Earth's crust made of for kids?
There are two types of crust: oceanic crust and continental crust. Oceanic crust is very thin and is mostly made up of basalt, which comes from lava. Continental crust is thicker than oceanic crust, is much older than oceanic, and is mostly made up of granite, which is usually only found in this type of crust.
What statement best describes Earth's crust and mantle?
the crust is thinner and less dense than the mantle.
