Question

1. which of the following defines the greenhouse effect?

the action of gases that are especially effective at reflecting all energy from the earths surface.
seasonal rains which arise due to seasonal winds
a curving pattern of winds over the earth due to the earths rotation
a phenomenon that allows sunlight to pass through the atmosphere, yet traps the heat between the atmosphere and the earth

Explanation:

The greenhouse effect is defined by gases allowing sunlight through the atmosphere but trapping heat between the atmosphere and the Earth. The other options describe different meteorological or atmospheric phenomena (wind patterns due to Earth's rotation, monsoon - like seasonal rains, and general gas reflection properties not specific to the greenhouse mechanism).

Answer:

A phenomenon that allows sunlight to pass through the atmosphere, yet traps the heat between the atmosphere and the earth.
