Geologists believe the continental crust ends at the Mohorovičić discontinuity, commonly known as the Moho. This boundary separates the continental crust from the underlying mantle, characterized by a distinct change in composition and density. The continental crust is primarily composed of lighter, granitic rocks, while the mantle consists of denser, mafic rocks. The depth of the Moho varies, typically ranging from about 30 to 50 kilometers beneath the continents.

What does continental temperature mean?

What is made of sediment and located at the bottom of the continental slope?
The accumulation of sediment at the bottom of a continental slope is referred to as continental rise. This phenomenon occurs in oceans throughout the world.
What is truncation in geology?
Truncation in geology refers to the abrupt termination of a rock layer or feature due to erosion or faulting. It results in a flat or angular surface where the rock unit ends, often indicating a change in the depositional environment or tectonic activity. Truncation can help geologists interpret the history and evolution of an area.
Is Isostasy a type of stress?
Isostasy itself isn't a type of stress. Restoring isostasy, however, puts stress on the crust. Allow me to explain: Isostasy is the process of the earth's crust floating on the mantle. When the crust suddenly gets heavier (this happens during an ice age close to the poles, the weight of the ice pushing the crust down), the crust will sink deeper into the mantle. This process is called "restoring the isostasy". The isostasy is reached when the upward force from the mantle (the buoyant force) and the downward force from the crust (gravity) are in balance again. When an ice age ends, the isostasy will be disrupted again, because all the weight of the ice on the crust will be gone. The crust will start to rise again, using the same forces as before, but in a reverse way. This process is still going on in Scandinavia, where the crust is still lifting up from the last ice age. As with all geological processes, restoring isostasy isn't fast: it can take thousands of years to restore the isostasy. Analog to the isostacy (but a lot quicker), is when you push down an icecube in a glass of water. The icecube will get lower into the water, as you push it down. but it will push back, because it's lighter then the water, and the buoyant force tries to make it float as good as possible. When it doesn't move anymore, it means the buoyant force and the force you are applying with your finger are in balance, and isostasy is reached.
What are unpaired ends of DNA called?
Unpaired ends of DNA are called single-stranded ends or overhangs. These are typically generated during processes like DNA replication or DNA recombination.
What is the difference between continental shelf and slope?
The continental shelf is a flattish area which extends from the shore out into the ocean and is made of continental crust. This ends in a slope (the continental slope) which descends to the abyssal plane, which is made of oceanic crust.
Why is oceanic crust usually much younger than continental crust?
Crust is produced at constructive plate boundaries, usually at mid ocean ridges. Here the plates are moving apart and magma wells up to form new basaltic rock. This means the youngest crust is usually part of an oceanic plate. When an oceanic plate collides with a continental plate, the denser oceanic plate sinks down in a subduction zone and ends up as magma again. The less dense continental crust is forced upwards and is preserved. Continental rocks are thus often very old.
Which portion of the continental margin where the continental shelf ends?

What is made of sediment and located at the bottom of the continental slope?
The accumulation of sediment at the bottom of a continental slope is referred to as continental rise. This phenomenon occurs in oceans throughout the world.
Where is the neritic zone located?
In oceans around the world. It's where the Continental Shelf drops off. It's, basically, the ledge.AnswerThis region in the ocean receives ample sunlight and extends to a depth of about 656 ft (200 m), the bottom is covered with seaweed. It has a low water pressure and stable temperature and is home to most of the world's greatest fishing areas. This zone is occupied by a large number of species, bacteria, dinoflagellates, oysters, etc. The neritic zone is the continental shelf after the intertidal zone to the continental cliff, where the continental crust ends and the oceanic crust begins.in the ocean
When does the Iditorod Race end?

What is a continental slope?
The continental slope is the area between the offshore shallows out to where the continental shelf dips steeply to the sea floor. It connects those two areas. The continental shelf is where the shallow waters of the ocean meet the shore. Farther out, the water gets progressively deeper, and this is the continental slope. At the outer edge of the continental slope, the bottom drops sharply away and plunges to the deep ocean. The Wikipedia article has more information and some drawings and diagrams. A link is provided. The steep slopingpart of the ocean floor termination of continental shelves is called continental slope.
