After reviewing the graph you posted above, there is one radioactive isotope that has a half life that is approximate to the same as the estimated time of the origin of Earth.
The radioactive isotope is called Uranium 238. You can also write this out as U-238 or uranium/u. Any of these are acceptable for the answer.
Answer:
Deep underground, beneath an extinct volcano
Explanation:
Diorite results from the partial melting of a mafic rock above a subduction zone. It is found in volcanic arcs, and in cordilleran mountain building, such as in the Andes Mountains.
Diorite is formed <u><em>deep within the Earth's crust from cooling magma that never made it to the surface</em></u>. It usually occurs as quite small intrusions often associated with larger intrusions like granite. Slow cooling produces the large crystals.
It's #1. Hope the answer helped.
The ice melts and it changes into a liquid state. Plus, the water droplets on the glass evaporated too.
