Aquatic and terrestrial are the two main types of ecosystems, and each has various sub-ecosystems. Forest, desert, grassland and mountain are four subtypes of terrestrial ecosystems, and marine and freshwater are aquatic ecosystem subtypes.
Forest ecosystems come in several types as well. For example, the tropical evergreen ecosystem possesses heavy plant and tree life, with each tree level serving as home to various animal types. Desert ecosystems get less than 25 inches of rain per year and account for about 17 percent of Earth's land.
The largest ecosystems are the marine ecosystems, which account for about 71 percent of Earth's surface and almost all of its water. The marine ecosystems are classified into divisions, such as coral reefs and estuaries.Learn More

Avalanches occur when large amounts of snow fall from steep slopes, either due to a break or fissure in the snow pack or due to an accumulation of too much snow for the slope's angle. In some cases, a snow pack can fracture due to a hiker or skier's actions, or rising temperatures may render the accumulated snow too unstable to stick to the slope.Full Answer >

The Earth's axis is positioned at an angle of 23.5 degrees away from the plane of the ecliptic. An objects axis, or axial tilt, also referred to as obliquity, is the angle between an objects orbital axis and rotational axis, or regularly, the angle between its orbital plane and equatorial plane.Full Answer >
