Natural selection is a way of environmental factors playing a role in the process of picking and choosing what stays and what goes
Irrigation causes an increase in salt which will kill plants. Pesticides poison water making it undrinkable. Pesticides can contaminate the soil for long periods of time.
The rock cycle<span> is a basic concept in </span>geology<span> that describes the time-consuming transitions through </span>geologic time<span> among the three main </span>rock<span> types: </span>sedimentary<span>, </span>metamorphic<span>, and </span>igneous<span>. As the diagram to the right illustrates, each of the types of rocks is altered or destroyed when it is forced out of its equilibrium conditions. An igneous rock such as </span>basalt<span> may break down and dissolve when exposed to the </span>atmosphere<span>, or melt as it is </span>subducted<span> under a </span>continent<span>. Due to the driving forces of the rock cycle, </span>plate tectonics<span> and the </span>water cycle<span>, rocks do not remain in equilibrium and are forced to change as they encounter new environments. The rock cycle is an illustration that explains how the three rock types are related to each other, and how processes change from one type to another over time.</span>
