Answers
Answer:
They live in a forest that has trees with dark colored bark.
Explanation:
Because the dark colored moths can blend in better with dark bark than light colored moths do, they don't stand out as much, so the predators(the birds) will eat the ones that they can find easier, which happens to be the light colored moths.

Describe the steps of the rock cycle and relate them to weathering, erosion, plate tectonics, and mountain building
Answers
Answer:
The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. For example, an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and change as they encounter new environments. The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle.
Explanation:
The Rock cycle is the geological concept, in which transitions between sedimentary, metamorphic, and igneous rocks over geologic time occurs. The transitions between rocks occur due to weathering, metamorphism, erosion, and sedimentation.
The steps involved in the rock cycle are:
Weathering refers to the breakdown or dissolving of the rocks on the Earth's surface. After the weathering, the process of erosion occurs in which rock particles and minerals are transported via plants, animals, wind, and water. The igneous rocks are formed by plate tectonics. The heat from the mantle fuels the plate tectonics, which converts the igneous and sedimentary rocks into metamorphic rocks. Mountain building is caused by the intense deformation of layered rocks and the activity of metamorphic and igneous rocks in the orogenic stage.
Thus, the rock cycle is involved in various processes and transitions among different types of rocks that occur in the rock cycle.
