Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Geologists have found rocks showing that about 700 million years ago, there was a time period when the amount of carbon dioxide in the atmosphere decreased. How did energy in the Earth system change during this time?
A
There was more energy in the Earth system and more energy absorbed by Earth’s surface, because more energy entered than exited. There was more energy in the Earth system and more energy absorbed by Earth’s surface, because more energy entered than exited.
B
There was more energy in the Earth system and more energy absorbed by Earth’s surface, because less energy entered than exited.
C
There was less energy in the Earth system and less energy absorbed by Earth’s surface, because more energy entered than exited.
D
There was less energy in the Earth system and less energy absorbed by Earth’s surface, because less energy entered than exited.
Explanation: 

Detailed explanation-1: -During this time, less energy entered the Earth system than exited. What is one change to the atmosphere that could have caused this? Carbon dioxide decreased, leading to less energy in the Earth system because less energy was trapped by gases and held in the atmosphere.

Detailed explanation-2: -How did energy in the Earth system change during this time? There was more energy in the Earth system and more energy absorbed by Earth’s surface, because more energy entered than exited.

Detailed explanation-3: -In the simulation; If you increased the amount of methane in the atmosphere How should the amount of energy in the Earth system change? There should be MORE energy absorbed by the Earth’s surface because less energy enters than exits.

Detailed explanation-4: -What happens when energy hits sulfur dioxide? When energy hits sulfur dioxide, more energy is created. Sulfur dioxide traps some energy and holds it in the atmosphere. Sulfur dioxide redirects (bounces) some incoming energy from the sun back toward outer space.

Detailed explanation-5: -This climate change is often referred to as “global warming.” Global warming is often linked to the burning of fossil fuels-coal, oil, and natural gas-by industries and cars. Warming is also linked to the destruction of tropical forests.
