9. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
10.Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage.
11.The feldspar-group, a very complex mixture of oxygen, silicon, aluminum and trace elements like sodium, potassium, calcium and more exotic elements like barium, are by far the most common minerals, making up almost 58% of all to a geologist accessible rocks, especially magmatic and metamorphic ones.
12.minerals are really very important in our life as they are used in our daily purposes and we use for example iron daily we use iron almirahs etc ,......
we use aluminium, diamond etc . in our daily life we use aluminium foils that are used to pack food items etc ,. there are many examples such as these ....

Answer:
The sum of all genetic traits in a population’s individuals at a given time
Explanation:
The gene pool can be defined as the sum of all genetic traits in a population’s individuals at a given time. This term is used when we talk about genes found in a population of any species. It doesn't matter if we talk about us, humans, or, for example, certain species of ants, trees, or algae.
When it comes to the survival of a species, it's better if it has a larger gene pool. If a genetic pool is large, there is a lot of diversity and the population of a species has better chances of surviving environmental stress that may impact it.
