Question 2 of 10

Nuclear fission involves which process?

forcing atoms to vibrate at incredibly high speeds
merging two smaller atoms into one larger atom
using a neutron to split the nucleus of an atom

... Nuclear fission involves splitting the nucleus of an atom into two smaller fragments with a neutron. This method usually involves isotopes of uranium or plutonium.

If two atoms of hydrogen are brought together in nuclear fusion, what do they form?

a helium atom
a hydrogen molecule
mega-hydrogen

... In nuclear fusion, two smaller atoms, usually hydrogen or hydrogen isotopes, come together to form a larger one (helium or helium isotopes). This is how the sun produces energy.

Question 9 of 10

What is nuclear winter?

a hypothetical scenario in which nuclear warfare causes clouds of dust to block out the sun
a theoretical situation in which the mass use of nuclear weapons leads to widespread infertility
another name for the Cold War

... In the nuclear-winter scenario, the widespread detonation of atomic weapons would raise great clouds of dust and radioactive material that would travel high into Earth's atmosphere and block out the sun. The weaker sunlight would lower the planet's surface temperature and hinder photosynthesis, resulting in the mass extinction of life.
