What layer of soil is closest to the surface?
The top layer of soil, called the topsoil, is closest to the surface. It is the layer that contains most of the organic matter and nutrients needed for plant growth.
What is between the asthenosphere and the outer core!?
the Mesosphere
What does the plates of lithosphere float on top of?
The plates of lithosphere float on top of the semi-fluid asthenosphere, which is located beneath the lithosphere in the Earth's upper mantle. The asthenosphere allows the plates to move and interact with each other due to its partially molten and more ductile nature compared to the lithosphere above it.
Which of earths mechanical layers is most easily deformed?
The asthenosphere is the Earth's mechanical layer that is most easily deformed. It is a semi-fluid layer located in the upper mantle that allows the tectonic plates to move and slide on top of it. This deformation is what causes the movement and interaction of tectonic plates, leading to processes like earthquakes and volcanic activity.
Is it true or false that the asthenosphere floats on the lithosphere?
Because of something called Isostacy-the gravitational equilibrium between lithosphere and asthenosphere, such that plates "float" at an elevation that dependes on the thickness and density. EX. Think floating ice cubes
The top of the asthenosphere is closest to Earth's surface?
Along a mid-ocean ridge
What happens when hot magma reaches the top of the asthenosphere?
When hot magma reaches the top of the asthenosphere, it can erupt through the Earth's surface, leading to volcanic activity. This process can create new landforms, such as volcanoes, and release gases and lava onto the surface.
What is the top layer of the earths surface?
crustSOIL
What is earths top surface?
It is called the crust.
Which type of seismic wave travels on top of Earths surface?
A Surface Wave.
What can be found directly under the plates of the earths crust?
The Earth's tectonic plates lay on top of the outer layer of the mantle. This layer is known as the asthenosphere.
What mechanical layer sits on of the asthenosphere?
The lithosphere sits on top of the asthenosphere.
What layer of soil is closest to the surface?
The top layer of soil, called the topsoil, is closest to the surface. It is the layer that contains most of the organic matter and nutrients needed for plant growth.
Is asthenosphere a plate boundary?
No. The asthenosphere is a ductile layer of the mantle that tectonic plates float on top of.
The asthenosphere is part of which layer of the earth?
The Asthenosphere is part of the Mantle of the Earth
Are tectonic plates part of the asthenosphere or the lithosphere?
Tectonic plates are segments of the lithosphere. They float on top of the asthenosphere.
What Is the theory that the earths lithosphere is divided into tectonic plates that move around on top of the asthenosphere?
A theory that says the lithosphere is divided into plates that move around on top of the asthenosphere is called '' plate tectonics''
