Answer:
A. The complete journey of one object around another.
Explanation:
Revolution can be defined as the complete journey of one object around another.
This ultimately implies that, the complete movement (motion) of the Earth along a path (an orbit) around the Sun or the Moon around the Earth is referred to as revolution.
Basically, it takes the Earth 365 1/4 days to completely move around the Sun.
Additionally, the earth rotation and revolution gives rise to the following phenomenon;
a. Day and night.
b. Seasons such as summer, winter, autumn, etc.
c. Creation of heat zones and ocean currents
Answer: (A), (B), (C) and (E)
Explanation:
- Coral reefs are found in the oceans formed by the accumulation of the skeletal remains of the invertebrates. They are found under water.
- Cold seeps refers to those area where the gases such as methane, hydrogen sulfide comes out through the vent, under water.
- Hydrothermal vents are the places where the hot intruding magma reacts with the sea water producing a vent.
- Rocky intertidal zone refers to the zone between a high and a low tidal mark.
Thus under the ocean, the structures such as coral reefs, cold seeps and hydrothermal vents forms where the tide is not so high and not so low.
Kelp forest is the odd one, that refers to those brown colored seaweeds, having high nutrients in salt water.
