Just like the water cycle, rocks undergo changes of form in a rock cycle. A metamorphic rock can become an igneous rock, or a sedimentary rock can become a metamorphic one. Unlike the water cycle, you can’t see the process happening on a day-to-day basis. Rocks change very slowly under normal conditions, but sometimes catastrophic events like a volcanic eruption or a flood can speed up the process. So what are the three types of rocks, and how do they change into each other? Keep reading to find out!
Answer:
A change in the size of the population may bring about changes in the culture. For example, food brought to this country by immigrant groups have become common in many American kitchens. Population increases and decreases affect the economy. For example, by increasing the demand for goods and services, a growing population may increase employment and stimulate the economy. An increase in the general population also means that there are more people occupying the same amount of space, which creates more crowded conditions. In addition, the larger population brings increased demand for energy, food, housing, schools, stores, and transportation. People also bring about changes simply by moving from one place to another. Migrations of people within a country can cause social changes, such as the loss of regional distinction within the country. Social and cultural changes also result from changes in the average age of a population. When fewer people are having babies, for example, there is less need for schools, recreation centers, and other services geared toward children.

<span>The correct answer should be a genetic drift. Mutations usually occur over a relatively short period of time and usually start with a single unit that transfers the mutation when they procreate. Genetic drifts separate entire populations and in time create new species that cannot procreate with the original species from whence they came.</span>
