Multiple choice

The water cycle in nature is called

  1. oxygen cycle

  2. hydrogen cycle

  3. hydrological cycle

  4. none of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The water cycle in nature is called Hydrological cycle. the water cycle, also known as the hydrological cycle or H2O cycle, describes the continuous movement of water on, above and below the surface of the Earth. Water can change states among liquid, vapor, and ice at various places in the water cycle. 

Multiple choice

The ocean surface currents follow clockwise circulatory paths in the northern parts of the Pacific and Atlantic oceans due to

  1. Convergence and divergence movements

  2. Impact of prevailing winds

  3. Coriolis force

  4. Density differences in sea water

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Coriolis effect is a deflection of moving objects when they are viewed in a rotating reference frame. In a reference frame with clockwise rotation, the deflection is to the left of the motion of the object; in one with counter-clockwise rotation, the deflection is to the right.

Multiple choice

Which of the following corals is used as an important environmental indicator in the study of long term climate change?

  1. Blue coral

  2. Elkhorn coral

  3. Black corals

  4. Bamboo coral

  5. Organ pipe coral
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bamboo coral  is a commonly recognised inhabitant of the deep sea, due to the clearly articulated skeletons of the species. These organisms may be an important environmental indicator in the study of long term climate change, as some specimens of bamboo coral have been discovered that are 4,000 years old.
