Front

What is the nitrogen cycle?

Back

The series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms.

Front

How does lightning contribute to the nitrogen cycle?

Back

It fixes atmospheric nitrogen into nitrates through high energy reactions.

Front

What is synthesis in chemical reactions?

Back

A type of reaction where two or more reactants combine to form a single product.

Front

What is double displacement in chemical reactions?

Back

A reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is the primary energy source driving chemical reactions during a lightning strike?

Back

Electrical energy from lightning.

Front

What is the role of nitrates in the nitrogen cycle?

Back

Nitrates are a form of nitrogen that plants can absorb and use for growth.

Front

What is the difference between a synthesis reaction and a decomposition reaction?

Back

A synthesis reaction combines reactants to form a product, while a decomposition reaction breaks down a compound into simpler products.
