divergent boundary
Yes, the mantle can be seen at a plate boundary where tectonic plates interact, such as at divergent or convergent boundaries.
A light-colored rock that has high silica content is likely to be granite. Granite is a common igneous rock composed mainly of quartz, feldspar, and mica, and is known for its high silica content and light color.
Granite is actually high in silica, which is why it is considered a felsic igneous rock. An example of an igneous rock low in silica is basalt, which is mafic in composition and contains less silica than granite.
Mt. Cleveland is a volcano caused by the convergent plate boundary between the Pacific Plate and the North American plate. Don't trust me, I just wrote this so that you would actually RESEARCH instead of rely on our answers because I'm stupid.
I would expect a light gray igneous rock to be rich in silica. Light gray color in igneous rocks is often associated with high silica content, which is typical of felsic or granitic compositions.
it is normally intermediate flow because of the silica content.

The East African Rift Valley
That would normally be magma with a low silica content.
You would be standing near a divergent plate boundary, where tectonic plates are moving away from each other. This boundary can be found in the middle of the North American Plate, spreading along the Mid-Atlantic Ridge in the Atlantic Ocean.
Australia is in the middle of the Australian-Indian plate. Antarctica has its own plate, but the actual continent doesn't get near the plate boundary. It's plate is called, oddly enough, the Antarctic plate. Who would have figured? You could say that Africa's edges aren't on plate boundaries, but there are some places in northern Africa that get pretty close to being on a boundary.
A convergent boundary forms when an oceanic plate is pushed under a continental plate. This process, known as subduction, can result in the formation of deep ocean trenches, volcanic arcs, and earthquakes.
This would be called a Spreading center, or a divergent plate boundary.
No, it would form along a separating (divergent) tectonic plate boundary.
Japan is at the meeting place of four tectonic plates: The Pacific Plate, The Eurasian Plates, The Philippine Plate, and the Okhotsk Plate (sometimes considered part of the North American Plate).
You would be most likely to find a boundary between a continental and an oceanic plate along a convergent boundary, where the denser oceanic plate subducts beneath the less dense continental plate. This often leads to the formation of deep-sea trenches and volcanic activity.
