What are the two spheres of the earth that effect both volcanoes and earthquakes?
The two spheres of the Earth that affect both volcanoes and earthquakes are the lithosphere and the asthenosphere. The lithosphere is the rigid outer layer of the Earth that is broken into tectonic plates, which can cause earthquakes when they move. The asthenosphere is a semi-fluid layer beneath the lithosphere that allows for the movement of tectonic plates and the formation of volcanic activity.
Why don't earthquakes occur in the asthenosphere?
Earthquakes do occur in the asthenosphere, which is a part of the upper mantle. However, they are less frequent and less detectable at the surface due to the high temperature and pressure conditions in this region. The asthenosphere is where the tectonic plates move and interact, causing seismic activity.
Which layer of the earth is like plasticine?
Asthenosphere
What is produced by movements of faults around the lithosphere and asthenosphere?
The lithosphere is the Earth's outermost crust. The asthenosphere is a ductile, somewhat deformable, layer 60-150 miles (100-250 km) below the Earth's surface, under the lithosphere. Movements between the two layers cause earthquakes.
What is the mechanical layer of earth that has most active convection?
The mechanical layer of the Earth that has the most active convection is the asthenosphere. Located just below the lithosphere, the asthenosphere is composed of partially molten rock that allows for the movement of tectonic plates. This convection helps drive plate tectonics, leading to geological phenomena such as earthquakes and volcanic activity. The dynamic nature of the asthenosphere plays a crucial role in shaping the Earth's surface.

Can you have an earthquake focus within the asthenosphere?
Earthquakes typically occur within the lithosphere, which is the rigid outer layer of the Earth. While the asthenosphere is viscous and can deform, it is less likely to generate earthquakes due to its ductile nature. Most seismic activity is associated with the brittle deformation of the lithosphere.

However, they are less frequent and less detectable at the surface due to the high temperature and pressure conditions in this region. The asthenosphere is where the tectonic plates move and interact, causing seismic activity.
Which layer of the earth is most affected by an earthquake?
The layer of the Earth most affected by an earthquake is the lithosphere, specifically the uppermost part called the crust. This is where the seismic waves are generated and cause the shaking and damage associated with earthquakes.
What is the rigid layer of earth surrounding the asthenosphere?
The rigid layer of Earth surrounding the asthenosphere is the lithosphere. It is composed of the crust and the upper portion of the mantle and is broken into tectonic plates that float on the semi-fluid asthenosphere below.
Which rigid layer of the Earth surrounds the asthenosphere?
The lithosphere surrounds the asthenosphere.
The lithosphere floats on a layer of the earth mantle called?
The lithosphere floats on a layer of the Earth's mantle called the asthenosphere. The asthenosphere is a semi-fluid layer beneath the lithosphere that allows the movement of tectonic plates.
The partially molten layer of Earth's mantle?
The partially molten layer of Earth's mantle is called the asthenosphere. It is located below the lithosphere and is responsible for the movement of tectonic plates due to its semi-fluid state. The asthenosphere facilitates the process of mantle convection, which drives the motion of Earth's lithospheric plates.
Which layer of earth contains asthenosphere?
The asthenosphere is located in the upper mantle. The asthenosphere is below the lithosphere, the brittle outer shell of the Earth.
What layer in earth has flowing rocks?
The Asthenosphere.
Which layer of the earth is like plasticine?
Asthenosphere
