Answer:
The five spheres of Earth are the geosphere, hydrosphere, atmosphere, cryosphere, biospheres.
The ocean is one environment that is comprised of both the hydrosphere and biosphere. The ocean, being nothing but water, serves as the whole known world to all marine life within, which serves as the biosphere component.
Mountainous environments are also made up of multiple spheres; including, but not limited to, cryosphere, geosphere, with a little bit of biosphere as well. Mountains--which are giant rock formations created by years of seismic activity--are mostly covered in snow near the peaks due to low temperature, which will melt at different points during the year. A small assortment of wildlife call these areas home, such as jackrabbits, white-tailed deer, mountain goat, bear, gray wolf, coyote, lynx, and wolverine.
