Is there still radiation in Hiroshima and Nagasaki? Radiation levels in Hiroshima and Nagasaki today are consistent with the very low background levels (natural radioactivity) found anywhere on Earth. There is no effect on the human body.
The plutonium bomb detonated at Nagasaki was actually more powerful than the one used at Hiroshima. Much of the reason for the higher casualty numbers in the latter city is due to the different physical characteristics of the two cities.

The correct option is D. Volcanic eruption released large amounts of water vapor into Earth's early atmosphere.
Earth’s first atmosphere had lots of water vapor but it almost lacked oxygen. Eventually, frequent volcanic eruptions put several different gases into the air. These gases created a new type of atmosphere for Earth. The volcanic eruptions spewed gases such as nitrogen, carbon dioxide, hydrogen, and water vapor into the atmosphere, but no free oxygen. Without oxygen, there could not be life on Earth.
