Explanation

Radiation is very slow on cloudy nights, resulting in less condensation on cloudy nights. 

 On cloudy nights, the clouds are thick  and trap  heat and water vapor in the clouds, resulting in very slow radiation. 

 This all shows why  dew levels drop on cloudy nights.

Explanation

• Producers, also known as autotrophs.
• They are organisms that can produce their own food through photosynthesis, using water (H2O), carbon dioxide (CO2), and sunlight to produce glucose and oxygen.

Explanation

Chlorofluorocarbons (CFCs) and other halogenated ozone-depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion.

Explanation

The troposphere is the lowest layer of Earth's atmosphere.

Most of the mass of the atmosphere is in the troposphere.

Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.

Major layers are 

troposphere

stratosphere

mesosphere

thermosphere 

exosphere

Explanation

• 99.9% to 100% of the energy entering the earth's atmosphere comes from the sun.
• 51% of the incoming energy is absorbed by the earth's surface i.e. the land and oceans.
  

Explanation

• A lake starts freezing because of the cold atmosphere. It will first freeze At the top surface
• ***
• concept:
• when the water freezes to ice, the ice becomes significantly less dense than the water and continues to float on the lake's surface.
• Below 4° Celsius, water becomes less dense as it gets colder, causing water to freeze to float to the top.
  
  

Explanation

The atmospheric pressure at any place is measured by a Barometer

***

The barometer was invented by Evangelista in 1644.

In fact, Agricultural Production consumes more fresh water than any other human activity.

 agriculture accounts (on average) for 70 percent of all freshwater withdrawals globally
