2. What do you think the relationship is between the Greenhouse Effect and Global Warming?

WHAT IS THE GREENHOUSE EFFECT?

Greenhouse Effectgases slow the movement of heat away from Earth’s surface

gases absorb and emit infrared radiation, which keeps heat on Earth.

This is considered a scientific FACT

WHAT ARE GREENHOUSE GASES?

Greenhouse Gases Carbon dioxide, methane, water vapor, and nitrous oxide.

They are mixed together

Without these gases, Earth would be very cold!

GLOBAL WARMING

The rise in CO2 and other Greenhouse Gases in the last few centuries is associated with the rise in global temperatures since the Industrial Revolution in the 1800s

Global Warming is considered to be a Scientific THEORY

Air Pollution Smoke and other harmful materials added to the air

Particulate Matter Tiny particles or droplets that are mixed in the air.

Ex. Dust, dirt, pollen, and salt

Fossil FuelsFuels formed from fossils

Ex. Coal

Smog
