The Mohorovičić discontinuity, commonly referred to as the Moho, is the boundary between the Earth's crust and the underlying mantle. It separates the solid, less dense rocks of the crust from the denser, more viscous rocks of the mantle beneath. This transition marks a significant change in both composition and physical properties of the Earth's materials.
What else can I help you with?
What two regions of the earth does the Moho discontinuity separate?
The Mohorovičić discontinuity (Moho) separates the Earth's crust from the underlying mantle. It is found beneath continents and beneath ocean basins.
What lead to the discovery of the Mohorovicic Discontinuity or 'Moho'?
The discovery of moho was through seismic waves...There are two 2 waves namely, Primary and Secondary waves...Secondary waves cannot pass through liquid and gasses. Thus, There is an abrupt increase in the velocity of earthquake waves (specifically P- waves) at this point.
Which is thicker the mantle or the two core layers cobmine?
The two core layers (outer and inner core) are denser and thicker than the mantle. The mantle is the layer between the core and the crust of the Earth, and it is thicker than the core layers.
Does the moho layer increase the speed of seismic waves?
No, the moho layer does not increase the speed of seismic waves. Instead, the moho layer marks the boundary between the crust and the underlying mantle, where seismic waves typically change in velocity due to the differing properties of these two layers.
What is an igneous intrusion between two sedimentary rock layers?
A laccolith is an igneous formation between two sedimentary layers
Which two Earth layers are separated by the Moho boundary?
The Moho boundary separates the Earth's crust from the mantle. It marks the boundary between the Earth's rigid outer layer (crust) and the underlying, more ductile layer (mantle).
It separates the mantle and the crust?
The Mohorovicic Discontinuity (also known as the Moho) separates the Earth's crust from the underlying mantle. It is the boundary where seismic waves change speed, indicating a change in composition and density between the two layers.
What two regions of the earth did the Moho discontinuity separate?
The Moho separates the crust and the mantle.
What are the two layers of discontinuity that are part of the interior structure of earth?
The two layers of discontinuity in Earth's interior are the Mohorovičić discontinuity (Moho) that separates the Earth's crust from the underlying mantle, and the Gutenberg discontinuity that marks the boundary between the mantle and the outer core. These discontinuities are characterized by changes in seismic wave velocity and composition.
Where is the place within the earth where the speed of seismic waves increases sharply?
The place within the Earth where the speed of seismic waves increases sharply is known as the Moho discontinuity, or Mohorovicic discontinuity. This boundary separates the Earth's crust from the underlying mantle, and seismic waves are thought to speed up due to the change in composition and density between these two layers.
What two regions of the earth does the Moho discontinuity separate?
The Mohorovičić discontinuity (Moho) separates the Earth's crust from the underlying mantle. It is found beneath continents and beneath ocean basins.
The core of the earth is made up of how many layers?
Inner core Outer core Lower mantle Upper mantle Astenosphere Moho Lithosphere Crust
What are the two physical layers of earth?
The two densest physical layers of the earth are the lithosphere and the asthenosphere.
What two layers of the earth are densest?
The two densest physical layers of the earth are the lithosphere and the asthenosphere.
What is the Moho or Mohorovicic Discontinuity?
The Mohorovicic discontinuity, usually referred to as the Moho, is the boundary between the Earth's crust and the mantle. The Moho serves to separate both oceanic crust and continental crust from underlying mantle. The Moho mostly lies entirely within the lithosphere; only beneath mid-ocean ridges does the Moho also define the lithosphere-asthenosphere boundary. The Mohorovicic discontinuity was first identified in 1909 by Andrija Mohorovicic, a Croatian seismologist, when he observed the abrupt increase in the velocity of earthquake waves (specifically P-waves) at this point.The Mohorovicic discontinuity is about 5 km below the ocean floor and 30 to 50 km beneath typical continents. The Moho is deepest beneath the Tibetan Plateau, where it is approximately 75 km below the surface.[
How were rocks used in the building of some types of castle?
Two layers of rocks (gaps in rocks filled with mortar) and earth in between the two layers of rocks.
What are the two physical layers of the earth are densest?
The two densest physical layers of the earth are the lithosphere and the asthenosphere.
