Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How is Earth a greenhouse?
A
Earth’s atmosphere does the same thing as the greenhouse.
B
Carbon Dioxide, a gas in Earth’s atmosphere, does what the roof of a greenhouse does.
C
The Sun shines through the atmosphere, warming the Earth’s surface.
D
All of the above
Explanation: 

Detailed explanation-1: -The greenhouse effect works much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. During the day, the Sun shines through the atmosphere.

Detailed explanation-2: -Conditions were also frequently sweltering between 500 million and 250 million years ago. And within the last 100 million years, two major heat spikes occurred: the Cretaceous Hot Greenhouse (about 92 million years ago), and the Paleocene-Eocene Thermal Maximum (about 56 million years ago).

Detailed explanation-3: -Earth is expected to continue to transition between glacial and interglacial periods until the cessation of the Quaternary Ice Age and will then enter another greenhouse state.
