What else can I help you with?
What is the moho in the earths layers?
The Moho, short for Mohorovičić discontinuity, is a boundary between the Earth's crust and the mantle. It marks a significant change in seismic wave velocities, indicating the transition from the less dense, rigid crust to the more dense, flowing mantle beneath.
The lower boundary of earth's crust is called what?
The lowest spots in the Earth's crust are found in the Mariana's Trench. It is located in the floor of the western North Pacific Ocean
The boundary between continental crust and oceanic crust occurs at the base of the?
The boundary between continental crust and oceanic crust occurs at the base of the lithosphere. This boundary is known as the Mohorovičić discontinuity, or Moho. It separates the less dense continental crust from the more dense oceanic crust below.
How many degrees is the earths mantle?
According to Scientists, the earthâ??s mantle temperature averages between 4,000 to 6,700 degrees Fahrenheit or 2,200 to 3,700 degrees Celsius.
Earths thin rocky outer layer is its .?
crust
The lower boundary of Earth's crust is called?
Moho
What is the sinking of regions of the earths crust lower elevation called?
?
What is the scientific defeniton of a fault?
A crack in Earths's crust along which rocks move. It is created by a transform boundary.
What is the name of the boundary were to plates of the earths crust move apart?
Constructive because new land is 'constructed'
Why does water float on Earth's surface?
Oceanic crust is denser than continental crust, it floats lower in earths mantle.
What is the lower boundary of crust?
The lower boundary of the Earth's crust is called the Mohorovičić discontinuity, or Moho for short. It is typically located between 5 and 10 kilometers beneath the ocean floor and around 20 to 70 kilometers beneath the continents.
What causes earthquakes and how do they affect us?
One simple answer involves a destructive plate boundary. When a destructive plate boundary slips, the resulting vibrations rush through the earths crust and you get an earthquake.
What is compression in plate tectonics?
it is the movement of the earths crust. it moves inwards towards other plates so the earths crust moves upwards therefore forming mountains, volcanoes etc
Why are there are almost no extrusive ultra basic rocks in earths crust?
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
If the earths crust separates at divergent boundaires and creates new crust why doesnt the earth grow in size?
This is because the size of the earth is relative stable or constant. Geologic activities do not actually changes earth size as a whole, but rather reshapes and resizes its landforms and continents. All that happen is just a recycling process whenever the earths crust seperates at divergence a boundary its being consumed somewhere else at a convergence boundary. And so on and on it goes, by this the earths overall size is maintained.
What are four layers that make up Earths atmosphere?
lower core, upper core, mantle, and crust
What is the size of the earths crust?
The Earths crust is approximately 650 km deep.
