Can an ocean be a result of plate boundaries pushing together?
No. Plate boundaries pushing together will, over enough time, get rid of an ocean. Plate boundaries pulling apart from each other will create an ocean given enough time.
How do divergent boundaries change over time?
They diverge (:
What do volcanoes demonstraight about plate boundaries?
Active volcanoes demonstraight the location of active plate boundries. Dormant volcanoes, such as the Japanese island chain, demonstraight how plate boundries have shifted over time.
How does the plate boundary along the west coast of the US change over time?
over time the plate boundary's great older and over heated , the west coast is finding out how to find out more about this .
How will the Great Rift Valley change over time?
Plate crates move
Why does the Australian mainland have no active volcanoes?
The Australian mainland doesn't have any active volcanoes at this time because it doesn't lie over any plate boundaries. Also, it isn't over any hot spot in the mantle at the present time. It has had volcanic activity in the past.
How are ocean ridge and deep ocean trench related to plate tectonics?
Ocean ridges are produced at divergent plate boundaries, where two plates are moving apart, and new crust is being created which fills the void. At an oceanic trench, two plates are colliding, and the more dense plate is subducted into the mantle. These collisions and separations of crust at their boundaries are responsible for the movement of oceanic and continental crust over time, originally referred to as continental drift.
Explain the features at a constructive boundary and why they form?
Constructive plate boundaries are those which are most commonly found between two oceanic plates. These locations include the South American Plate and the African plate, Indo-Australian Plate and Antarctic Plate and between the Nazca and Pacific Plate. the worlds longest constructive boundary is the Mid-Atlantic Ridge. These boundaries can be defined as boundaries which create new crustal material. The plates involved in this kind of boundary are diverging, or moving apart, which is the reason the boundaries are sometimes called 'divergent boundaries'. These plates cause some small-scale localised earthquakes. They also cause underwater volcanoes, where the magma rises from the mantle and cools quickly to form solidified igneous rock. Over time this rock builds up to create a chain of volcanoes, some of which become so large that they become volcanic islands such as ones found around Iceland. also associated with this type of boundary are smaller, transform boundaries running at right angles from the main fault.

What are facts about both California and Japan have frequent earthquakes?
California and Japan are both on tectonic plate boundaries, so when those boundaries move it causes massive earthquake, which is why you hear about it on the news all the time :)

What type of sciences study tectonic plates?
Several things are studied by Earth scientists who specialize in tectonics. Plate boundaries, plate tectonics, boundaries, continental drift, mountains, and volcanoes are all studied.
