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

  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


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 _______.

  1. Increases as the temperature increases

  2. Decreases as the temperature increases

  3. Increases as the temperature decreases

  4. Decreases as the temperature decreases


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.

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

  1. Tides

  2. Water cycle

  3. Rain

  4. Ocean currents


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.

Acid precipitation is now regarded as a serious problem in some European and Asian countries. Its major cause or source is __________________.

  1. discharge of effluents into neutral or slightly alkaline land where the acidic components precipitate

  2. emissions of sulphur oxides and nitrogen oxides from thermal power plants and burning the fossil fuels; these oxides dissolve in atmospheric water vapour and fall back on earth as acid rain

  3. natural carbondioxide released during respiraion of living organisms dissolves in water, forming carbonic acid which is chief contributor to acidity in rain water

  4. chloroflurocarbons readily react with various chemicals near the earth's surface, producing acidic intermediates which cause acid precipitation


Correct Option: B
Explanation:

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Cloud, snow, sleet and hail are the forms of __________.

  1. Plants

  2. Precipitation

  3. Soil

  4. Pressure


Correct Option: B
Explanation:

Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth.

The rain that falls from clouds but freezes before it reaches the ground is called sleet or ice pellets.

Snow is precipitation that falls in the form of ice crystals

Hail  forms when very cold water droplets freeze, or turn solid, as soon as they touch things like dust or dirt

Water vapor in the atmosphere is visible as clouds and fog.

When water particles condenses on air and dust, it forms __________.

  1. mist

  2. fog

  3. frost

  4. vapour


Correct Option: A
Explanation:

It forms mist. It is a phenomenon caused by the small water droplets of water suspended in the air. When the warm moist air meets the sudden cooling, mist is formed.

In air, amount of water vapor is classified as ______.

    1. wind

    2. precipitation

    3. humidity

    4. temperature


    Correct Option: C
    Explanation:

    The amount of water vapor in the air is known as humidity. It can make hot temperatures even more unbearable than they already are. It affects both weather as well as climate. It also affects global climate change. Both low humidity as well as high humidity is harmful for us. Humidity is of two types:- Absolute humidity and Relative humidity.

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

    1. Water cycle

    2. Tides

    3. Ocean currents

    4. Rain water


    Correct Option: A
    Explanation:

    The process by which water continually changes its form and circulates between oceans, atmosphere and land is known as water cycle. In the water cycle, water from oceans, lakes, swamps, rivers, plants can turn into water vapour. Water vapour condenses into millions of tiny droplets that form clouds. Clouds lose their water as rain or snow, which is called precipitation. Precipitation is either absorbed into the ground or runs off into rivers. Plants take up the water that was absorbed into the ground. Plants lose water from their surfaces as vapour that goes back into the atmosphere. Water that runs off into rivers flows into ponds, lakes, or oceans where it evaporates back into the atmosphere. This cycle continues.

    When precipitation comes down to the earth in the liquid form, it is called.

    1. Cloud

    2. Rain

    3. Snow

    4. Water


    Correct Option: B
    Explanation:
    Precipitation is part of the water cycle. In the water cycle, water from oceans, lakes, swamps, rivers, plants can turn into water vapor. Water vapor condenses into millions of tiny droplets that form clouds. Clouds lose their water as rain or snow, which is called precipitation. When precipitation comes down to the earth in the liquid form, it is called rain. People rely on precipitation for freshwater to drink, bath, and irrigate crops for food.
