A layer in the Earth’s atmosphere called ionosphere facilities radio communication. Why? [2011]
1. The presence of ozone causes the reflection of radio waves to earth.
2. Radio waves have a very long wavelength.
Which of the statements given above is/are correct?CorrectStatement 1 is wrong, ionosphere contains charged particles due to which electromagnetic radio waves gets reflected and communication becomes possible. Ozone is found mainly in stratosphere and in traces in troposphere. Its main function is absorption of UV rays. While the ions give the ionosphere its name, it is the free electrons that effect the radio waves and radio communications. Also Radio waves have the longest wave length in the EM spectrum.

17. Question
Consider the following pairs: [2013]
1. Electromagnetic radiation
2. Geothermal energy
3. Gravitational force
4. Plate movements
5. Rotation of the earth
6. Revolution of the earth
Which of the above are responsible for bringing dynamic changes on the surface of the earth?CorrectFrom electromagnetic radiation to revolution of the earth, everything is responsible for bringing dynamic changes on the surface of the earth. For example: Electromagnetic radiation brings changes in the field of microwaves, wavelengths of radio, UV rays, infra red rays, X rays and gamma rays. Geothermal energy is the heat received from the earth’s core. This heat continuously flows outward. It transfers to the surrounding layers of rock, the mantle. When temperature and pressure becomes very high some mantle rocks melt becoming magma. It then either comes out as lava or heat up the nearby rocks and water which comes out as hot springs or geysers. Gravitational force is constantly working on all physical bodies. It is giving weights to objects with mass and causes them to fall to the ground when dropped. Plate movement is a dynamic change on the surface of the earth. It explains many aspects of the interrelationship of volcanoes, earthquakes, climate change, and the evolution of life itself. Everything about our planet is related either directly or indirectly to plate tectonic. Rotation causes day and night. Revolution causes seasons, change in the length of day and night.

- Question 20 of 20
20. Question
The annual range of temperature in the interior of the continents is high as compared to coastal areas. What is/are the reason/reasons? [2013]
1. Thermal difference between land and water
2. Variation in altitude between continents and oceans
3. Presence of strong winds in the interior
4. Heavy rains in the interior as compared to coasts
Select the correct answer using the codes given below.CorrectThe first statement is correct. One major factor affecting the distribution of the temperature of Earth is distribution of Land and Oceans. Since there is more land in Northern Hemisphere and more waters in Southern hemisphere and there is a big difference between the specific heat of land and water; the loss of heat from the continents is bigger than the oceans. The continents get heated faster and get cooled faster in comparison to the Oceans. This is the reason that the temperatures of the Oceans are moderate while that of continents is extreme. The moderating effect on temperature of the land due to proximity of the seas is called Maritime influence. The increasing effect on temperature of the land at interior of the continents is called Continental Influence.
