1. Consider the following statements:
- Unlike the coral islands, the volcanic islands are very much lower and emerge just above the water surface.
- Oceanic islands can be either Volcanic Island or Coral island.
- Ocean currents are the horizontal motion of water while the waves are the vertical motion of water.
- Both the ocean currents and waves cause movement of water from one place to another.
- They secrete a comparatively high amount of calcium carbonate and build reef very quickly.
- They are found in the Mediterranean Sea.
- Temperature decreases steadily with increase in height.
- Thickness of the troposphere is highest at the equator and lowest at the poles.
- Ionosphere layer is responsible for radio transmission on earth.
Temperature of air decline steadily in Troposphere, which is the lowermost layer of the atmosphere. After this, the temperature remains constant for some height and then increases in the stratosphere. Height of the troposphere is moreover the equator due to strong convection currents. It is minimum at the poles. Ionosphere contains electrically charged particles called ions which reflect radio waves and thus makes radio transmission possible on the earth.
