Oceanic crust spreads at MID-OCEAN RIDGES, creating new crust and slowly enlarging the ocean basin.
SUBMARINE CANYONS are deep valleys at passive continental boundaries. They are likely carved out by TURBIDITY CURRENTS, which occur when sediment-laden water rapidly moves down slope.
Melt from the subducting plate rises to the surface, erupts through the crust on the overriding plate and forms CONTINENTAL VOLCANIC ARCS on continents, or VOLCANIC ISLAND ARCS in the ocean.

The image below shows that about 30 percent of the Sun’s energy is reflected and scattered back into space. How would a 50 percent increase in Earth’s albedo impact average surface temperatures?
Surface temperatures would increase, causing a decrease in surface water and/or ice on Earth, and would thus cause a further increase in albedo.
A higher albedo means more of the Sun's radiation is absorbed by Earth's surface.
Ice sheets would advance, thereby increasing Earth's overall albedo and further cooling Earth's surface.
Higher albedo would result in cooler temperatures on Earth.
The atmospheric high-pressure cells over North America in the map suggest that the atmospheric patterns shown most likely represent which season for the northern hemisphere?
Spring
Winter
