Why is Earth's surface rarely impacted by large objects that enter Earth's atmosphere?
Because Earth has such a dense atmosphere, friction causes most objects to burn up before they reach Earth's surface.
Because Earth's atmosphere is able to catch most objects like a volleyball net, and it bounces these objects back into space.
Because Earth's atmosphere has so much water vapor that it dissolves most objects that travel toward Earth.
Because Earth's atmosphere is magnetic and it repels all objects that try to travel toward Earth.

Which argument best uses evidence to link human activities that release carbon dioxide gas to changes in Earth’s climate?
***Experiments show that carbon dioxide gas traps and radiates heat, so a big enough increase in atmospheric carbon dioxide will cause Earth’s atmosphere to warm.
Computer models predict that Earth’s climate will continue to warm as human release of carbon dioxide continues, so the relationship between human activities and climate change is well established.
Increases in Earth’s climate have occurred at the same time that its atmospheric carbon dioxide has increased significantly.
The recent increase in atmospheric carbon dioxide is so much greater than past changes that it must be caused by human activity rather than natural forces.

The sample was taken about 200 meters below sea level.
The sample was taken about 800 meters below sea level.
