The Particle Theory Says -

That all matter consists of particles that are constantly moving. The more energy they have, the more they move.

That particles is what may be the answer to Earth's destruction

I don't know.

When an object is heated and cooled..?

When an object is heated, it has more energy. When an object is cooled it has less energy.

When and object is heated, it has less energy. When an object is cooled, it has more energy.

Gases in the air - Nitrogen

Nitrogen cannot be breathed in by humans but is essential for life.

Nitrogen is breathed in and is bad for humans.

What does nitrogen do?

Bacteria takes out the nitrogen from the air and puts it into soil. These nutrients from the nitrogen helps the plants to grow. When an animal goes to eat the plants, it takes it in with them, and puts it back into the air through their waste.

Nothing, it's just there for fun.

Gases in the air - Oxygen

Oxygen can be breathed in, it is odorless and colourless. It is essential for the survival of animals and for burning fuels.

Oxygen is useless?

Gases IN THE AIR -

21% Oxygen and 78% Nitrogen - The remaining is many more gases but in small amounts.

78% Oxygen and 22% Nitrogen - After all, oxygen comes from trees, right?

Photosynthesis -

Carbon Dioxide + Water + Light + Glucose + Oxygen = PHOTOSYNTHESIS

Light + Water + Oxygen = PHOTOSYNTHESIS

Respiration -

Glucose + Oxygen + Carbon Dioxide + Water + Energy = RESPIRATION

Water + Energy + Glucose = RESPIRATION
