Do hot spots only form in oceanic crust?
no they also occur up your mom
Are oceanic plates only made up of oceanic crust?
yes but oceanic crust is younger than continental crust because of deep sea trenches
What is a characteristic of subduction?
The correct answers are - B. Where oceanic crust meets continental crust, and C. Earthquakes.Subduction zones appear only on places where a crust of lower density (oceanic crust) meets a crust of higher density (continental crust).On the places where the oceanic crust meets the continental crust, the oceanic crust goes beneath the continental crust, this makes changes and readjustments in the inner part of the crust, and plus there's significant pressure from the mantle layer from beneath, so earthquakes are a very common occurrence.Check all that apply. A. Broad river deltas B. Where oceanic crust meets continental crust C. Earthquakes D. Two continents collide
Why do composite volcanoes occur at the boundary between oceanic crust and continental crust?
The simple answer: Oceanic crust is more dense than the continental crust, so it goes under as the two plates ram into each other. (This is called subduction) This submerged crust melts into magma, and collects into a large pool under the continental plate where it went under. The pool of magma forces its way up to form a volcano, which sits in front of us and blows when least expected. The whole process takes a very long time. Also, it only happens in convergent boundaries.

Does sea-floor spreading occur in oceans only?
It occurs in the oceanic crust!!!

How many tectonic plates are made of only oceanic crust?
how many tectonic plates are made of oceanic crust
Does an earthquake occur only in continental crust?
No, earthquakes can occur anywhere in the crust, oceanic crust or continental crust. An earthquake occurs when the hard brittle solid material of the crust fractures under stress. Earthquakes cannot occur deeper than the crust (the mantle is plastic and flows slowly under stress instead of fracturing, the outer core is liquid and flows even easier than the mantle).

What is the difference of continental crust and oceanic crust?
Two differences are that the oceanic crust is more dense than continental, and continental crust is composed mostly of granite, while oceanic is mostly basalt
Describe volcano distribution?
Volcanoes are distributed as they are because most occur at the boundaries of the world's tectonic plates. Subducted crust rises as magma at constructive or destructive plate boundaries, and escapes through vents in the crust, often forming volcanoes on the surface. The only exceptions to volcanoes at plate boundaries are what are known as "hot-spot" volcanoes, that occur where a particular section of the Earth's crust is very thin and being heated by the mantle below. An example of this would be the Hawaiian Islands.
Why are there volcanoes popping up everywhere?
They do not pop up everywhere. they only occur along the fault lines (where the plates that form the earth's crust meet). Volcanoes have been occurring along fault lines since the creation of the earth's crust (billions of years)
Are subducting plate and oceanic plate the same?
No. While only oceanic crust can subduct it is not always subducting. When two oceanic plates converge, only one of them subducts.
