What rock is actually glass and has sharp edges?
Obsidian is a natural volcanic glass with potentially sharp fracture edges.
The edges of most lithospheric plates are characterized by?
frequent volcanic activity
When a mineral breaks with rough edges what is that called?
streak
When a pyrite crystal is hit with a hammer it breaks into pieces with smoothly curved edges What is the new type of rock?
Fracture :)
Where do most volcanic eruptions occur?
Volcanoes are located throughout most of the world. The most active volcanoes are found on the so-called "ring of fire" in Pacific Ocean. Indonesia has several volcanoes including Krakatoa. Hawaii's Kilauea produces the most lava of all active volcanoes in the world. North America has Mt. St. Helens and Mt. Rainier in Washington, USA. Mexico has several including Parícutin and Nevado de Toluca. Europe has Mt. Etna. Generally, volcanoes are located near tectonic plates that are converging or diverging.

What is the process called that roughens the edges of rocks and causes grooves and breaks in them?
That depends on what the object with rough edges and grooves is.
Volcanic eruption happens where?
mainly in the ring of fire, the pacific plate, edges of the pacific ocean
What happens when Ice breaks off from the edges of Antarctica?
it will float to warmer Waters and eventually melts.
Are volcanic eruptions caused by the movements of tectonic plates?
Usually, volcanic eruptions above water are the result of a magma-plume burning through a spot in the Earth's crust, or by the rising part of a magma convection cell. Such conditions are often found near the edges of the continental plates. There are also spots where the Earth's crust is so thin that magma breaks through even without there being a plume, such as near oceanic ridges. Most of the volcanic eruptions on this planet take place under water, near oceanic ridges.

Why do the epidermal cells have had there edges folded over?
The epidermal cells have their edges folded over which is part of the structure. This is as a result of the growth factors which makes the cells to proliferate.
