Because of hail, crops may get destroyed and loss of life and property may also occur. What type of precipitation is this?

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Concentric layer

  2. Hail shower

  3. Hailstones

  4. All of above

Show answer
Correct Option: B
Explanation:

The precipitation where hail occur with rainfall, that type of precipitation is called as hail showers. Because of hail, crops may get destroyed and loss of life and property may also occur.

Why hail do not occur in cold zones?

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Because of lack of upward flow

  2. Because of high upward flow

  3. Because of fall in temperature

  4. Because of rise in temperature

Show answer
Correct Option: A
Explanation:

Hail do not occur in cold zones because of lack of upward flow.

Rain shadow area is associated with which type of rainfall?

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Convectional rainfall

  2. Orographic rainfall

  3. Cyclonic rainfall

  4. Frontal rainfall

Show answer
Correct Option: B
Explanation:

Rain shadow area is associated with orographic rainfall. When the saturated air is obstructed by land form barrier such as mountain, it forced to ascend and as it rises, it expands and temperature falls. As a result, condensation takes place and rainfall occurs. In this type of presentation, the windward slope of the mountain receives maximum rain and the leeward slope remains generally drier and is known as the rain shadow area.  

What is cyclone?

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Specific air formation when the pressure at an area is less than the surrounding regions.

  2. Specific air formation when the pressure at an area is high than the surrounding regions.

  3. Rainfall

  4. All of above

Show answer
Correct Option: A
Explanation:

Specific air formation when the pressure at an area is less than the surrounding regions. This is called cyclone. Air from the surrounding region comes towards the center of the cyclone and starts moving upwards.

Why in equatorial areas, the surface get heated?

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Because of sun's heat

  2. Because of hot air

  3. Because of acid rain

  4. None of these

Show answer
Correct Option: A
Explanation:

In equatorial areas, the surface gets heated because of the sun's heat and the air near it also gets heated. As it gets heated, it spreads and becomes lighter and moves upwards.

The Wind which descends on the Leeward Side is heated adiabatically and is called ____________.

  1. loo

  2. trade wind

  3. katabatic wind

  4. monsoon

Show answer
Correct Option: C
Explanation:
Katabatic winds
Katabatic wind  is the generic term for downslope winds flowing from high elevations of mountains, plateaus, and hills down their slopes to the valleys or planes below. Katabatic winds exist in many parts of the World and there are many different names for katabatic winds depending where they are located and how they are formed. 

Warm, dry katabatic winds occur on the lee side of a mountain range situated in the path of a depression. Examples for these descending, adiabatically warmed katabatic winds are the Foehn winds. 

Cold and usually dry katabatic winds, like the Bora, result from the downslope gravity flow of cold, dense air. Katabatic flows slumping down from uplands or mountains may be funneled and strengthened by the landscape and are then known as mountain gap wind such as the Santa Ana, mountain breeze or drainage wind. The gentler katabatic flows of hill slopes produce frost hollows. Mountain breezes are part of a local wind system. When the mountainside is heated by the Sun the mountain breeze will break down, reverse and blowing upslope. These winds are known as valley wind or anabatic wind.

Which o the following is mainly responsible for the orographic rainfall occurs?

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Because of the obstruction of the mountains

  2. Because of the sun's heat

  3. Because of the convectional process

  4. None of these

Show answer
Correct Option: A
Explanation:

Winds coming from lakes or seas are moisture-laden. They are obstructed by the high mountain ranges coming in their way. They start going upwards along the slope of the mountains, the temperature of these winds drop and condensation occurs and rainfall takes place. Thus because of the obstruction of the mountains, this type of rainfall occurs.

The capacity of the air to hold water vapour _______.

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Increases as the temperature increases

  2. Decreases as the temperature increases

  3. Increases as the temperature decreases

  4. Decreases as the temperature decreases

Show answer
Correct Option: A
Explanation:

Increases as the temperature increases,

The water-vapor content of the atmosphere varies from place to place and from time to time because the moisture-holding capacity of air is determined by temperature. At 30 °C (86 °F), for example, a volume of air can contain up to 4 percent water vapour. At -40 °C (-40 °F), however, it can hold no more than 0.2 percent. The more the temperature more is the water holding capacity.

Water on Earth comes mainly from which of the following?

  1. Taps

  2. Rain

  3. Wells

  4. None of these

Show answer
Correct Option: B

The process by which water continually changes its form and circulates between oceans, atmosphere and land _____________.

evs - i hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Tides

  2. Water cycle

  3. Rain

  4. Ocean currents

Show answer
Correct Option: B
Explanation:

The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.
