Question

how do greenhouse gases trap heat? they chemically combine to create sunlight. they reflect all sunlight back into space. they reflect solar radiation back towards the earth.

Explanation:

To determine how greenhouse gases trap heat, we analyze each option:

• The first option is incorrect because greenhouse gases do not create sunlight through chemical combination.
• The second option is incorrect as greenhouse gases do not reflect all sunlight back to space; instead, they allow some sunlight in and trap heat.
• The third option is correct: Greenhouse gases (like CO₂, methane) absorb and re - emit infrared radiation (solar radiation that has been converted to heat at the Earth's surface), reflecting it back towards the Earth, which warms the planet.

Answer:

The correct option is: They reflect solar radiation back towards the Earth.
