absolute dating uses radioactive isotopes of atoms to find out exactly how old certain rocks and minerals are. In the past there were (more or less) atoms of radioactive Uranium

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

weathering is the answer.

the answer is: reproductively

i think i spelled it wrong lol

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
