Think about a drop of water in the ocean. if it were to go through the whole hydrologic cycle, number the steps that would follow. 1. step 1 the groundwater flows into a river which empties back into the ocean. 2. step 2 the atmosphere is cooler, so the drop of water would change from a gas back to a liquid through condensation. 3. step 3 evaporation would change the drop of water to water vapor, a gas, which would rise into the atmosphere. 4. step 4 as more water vapor condenses into liquid, the drop of water will eventually drop to earth's surface as precipitation. 5. step 5 the drop of water falls to the ground as rain and is absorbed as ground

answer; /// i believe that the correct answer is (50%);

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
