Question

Question 5: Consider two coastal regions at the same latitude. Region (1) is next a cold ocean current, and (2) is next to a warm ocean current. The weather for region (1), compared to region (2) is likely to be:
A-Wet.

B-Warm.

C-Cold and Dry.

D-Windy.

E-Cloudy.

Question 6: Why does the temperature increase with increasing altitude in the stratosphere, unlike the troposphere?

A-Absorprtion of solar energy by ozone.

B-Energy is absorbed by stratospheric clouds.

C-The stratospheric clouds act as a blanket, retaining heat.

D-The air is thinner in the stratosphere.

E-Global warming due to changing CO2 levels.

Question 7: A temperature inversion within the troposphere is when:

A-Warm air overlies cool air.

B-Cool air overlies warm air.

C-The air is generally cooler than expected at all levels.

D-The air is generally warmer than expected at all levels.

E-Is when the temperature is converted to the SI (metric) system.

Answer 1

Answer:

1- Option (C)

2- Option (A)

3- Option (B)

Explanation:

The warm ocean currents are responsible for the transportation of warm and moist air to the coastal region, whereas the cold ocean currents are responsible for carrying the cold and dry air to the nearby coastal areas.

Therefore, the region (1) will experience a cold and dry type of weather.

The stratosphere is the layer that is just above the troposphere and extends from a height of about 10 to 50 km above the ground surface. Here the temperature increases with the increasing height due to the presence of Ozone layer (O₃) that absorbs the incoming solar radiations.

Troposphere is the interior layer of the atmosphere that extends from the ground surface up to a height of about 10 km. Here, the temperature decreases with the increasing altitude. The air near the ground surface is compact and dense, due to which the temperature remains high. As the warm air rises up it interacts with the cold air that is situated over the warm air. Due to this, the air cools down and sinks to the bottom.

Hence, the correct answers are mentioned above.
