6. Ice can form from a gas through the process of_____.
7. Hydrogen compounds in the solar system can condense into ices only beyond the_____.
8. ______allows us to determine the age of a solid rock.

Answer 1

1. Solar nebula
2. Planetesimal
3. Heavy bombardment
4. Accretion
5. Solar wind
6. Condensation
7. Frost line
8. Radiometric dating

Step-by-step explanation:

Solar nebula is a gaseous cloud and it have been considered that when it condensed, Sun and other planets are formed.

Planetesimal term is used for an object which is formed from rock, dust and some other materials.

When growth occurs due to gradual accumulation of layers then it is called Accretion.

A stream of charged particles (electrons and protons) having extreme energy and flowing outward from the Sun at speeds approximately 900 km/s and at a temperature of 1 million degrees is termed as Solar wind.

Radiometric dating is the name of technique that is used to calculate the age of the materials such as rocks or carbon.
