Explanation

Open garbage dumps release toxic gases into the air, leading to air pollution (e.g., methane, ammonia).

When rainwater passes through waste, it forms leachate, which contaminates groundwater and causes water pollution.

Explanation

A beta particle, also called beta ray or beta radiation (symbol β), is a high-energy, high-speed electrons emitted by the radioactive decay of an atomic nucleus during the process of beta decay.

Explanation

The ozone layer protects living things from too much ultraviolet  from entering the atomsphere.

Oxygen layer in the atmosphere

Ozone protects us from the harmful ultraviolet radiation of the sun.

Ozone formula: O3

The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth's surface, in the stratosphere.

The ozone layer is depleting: Air pollution

Explanation

• The ozone layer is a layer of gas in the stratosphere that contains a high concentration of ozone (O3).
• It absorbs most of the sun's ultraviolet (UV) radiation, protecting the Earth from harmful UV rays.

Explanation

The ozone layer lies in the stratosphere, approximately 15-40 kilometers (10-25 miles) above the Earth's surface.

The stratospheric ozone layer is Earth's “sunscreen”  protecting living things from too much ultraviolet radiation from the sun.

Oxygen layer in the atmosphere 

Ozone protects us from the harmful ultraviolet radiation of the sun.

Ozone formula: O3

The ozone layer is depleting: Air pollution

IMPORTANT QUESTIONS AND INFORMATION RELATED TO "GREEN HOUSE EFFECT"

Green House Effect means the Trapping of Solar energy due to atmospheric carbon dioxide

The greenhouse effect is a good thing.

It warms the planet to its comfortable average of 57 degrees Fahrenheit (13.9 degrees Celsius)

The greenhouse effect keeps life on earth, well, livable.

The Green House Effect is caused by an excess of Carbon dioxide

The greenhouse effect causes Global warming

Methane gas is 80 times potent than CO2 in Green House Effect

Explanation

Wind blows from areas of high pressure to areas of low pressure.

This is because air molecules move from areas of higher concentration (high pressure) to areas of lower concentration (low pressure) to equalize the pressure difference.

This movement of air is what we feel as wind.

Explanation

1 becquerel = 1 radioactive decay per second = 2.703x10^-11 Ci.
