Explain the greenhouse effect and name two greenhouse gases.

The greenhouse effect is the process by which certain gases in the atmosphere trap heat, warming the planet. Two greenhouse gases are carbon dioxide and methane.

How does the Earth's reflectivity (albedo) affect climate? Give an example.

The Earth's reflectivity determines how much solar radiation is reflected back into space. High reflectivity (e.g., from ice or snow) cools the planet, while low reflectivity (e.g., from dark surfaces) warms it. Melting ice caps reduce reflectivity, leading to further warming.

Weather versus Climate

7th Grade•180 minutes•NGSS MS-ESS2-5

Learning Objective

I can differentiate between weather and climate and explain the factors that affect each.

Key Concepts

Weather is what it looks like outside right now, while climate is what it looks like over a long period of time.

Factors that affect weather and climate include the amount of sunlight, oceans, atmosphere, and landforms.

Greenhouse gases like methane, carbon dioxide, and water vapor slow the loss of heat from our planet, impacting the climate.
