Q3 Nonrenewable Resources Flashcard/ Exothermic/Endothermic

Front

What is a major source of methane, a potent greenhouse gas?

Back

Landfills are a major source of methane, which is released during the decomposition of organic waste.

Front

In an exothermic reaction, how is energy represented in a chemical equation?

Back

Energy is represented as a product in an exothermic reaction.

Front

What is a major environmental issue caused by burning fossil fuels?

Back

The burning of fossil fuels leads to an increase in carbon dioxide levels in the atmosphere.

Front

Front

What are fossil fuels?

Back

Fossil fuels are energy sources formed from dead plants and animals over millions of years.

Front

Define exothermic reaction.

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat.

Front

Define endothermic reaction.

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases.

Front

List three examples of fossil fuels.

Back

Coal, oil, and natural gas are three examples of fossil fuels.

Front

What is the role of carbon dioxide in climate change?

Back

Carbon dioxide traps heat in the atmosphere, contributing to global warming.
