Trenches are formed by subduction, a geophysical process in which two or more of Earth's tectonic plates converge and the older, denser plate is pulled beneath the lighter plate and deep into the mantle, causing the seafloor and outermost crust ( the lithosphere) the bend and form a steep, V- shaped depression.
Answer:Sea Floor Spread is where the oceanic crust splits to form new crust on the earth forming ridges.
Continental slide is when tectonic plates slide past one another formed at the fault line causing earthquakes.
Transform boundaries can be explained by showing what happens after they slide almost like how after an earthquake the houses are destroyed and some have sunk into the grounds fault line.
Continental Crust is the crust of the earth that us humans and animals live on formed by divergent boundaries in the crust.
Explanation:
The mining of oil shale requires LARGE AMOUNT OF WATER.
The processing of oil shale require large amount of water which is needed for the processing activities of oil shale. This is a big challenge to the mining of oil shale because most of oil shale deposits are found in semi arid regions where water is scarce.<span />
