2. CCC Cause and Effect During the water cycle, water evaporates, rises into the atmo- sphere, and eventually falls back to Earth's surface as precipitation. What is the original source of energy that produces these changes

it's filtration, but this is an assumption so my apologies if i got this

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
