Solute is the substance that dissolves
- Solute is a minor component
- Solvent is a major component
- Solutions is a mixture where the solute is uniformly distributed in the solvent.
- Solution is homogeneous mixture that contains particles the size of a typical ion or small molecule.
- The mass of the solute dissolved per unit volume of solvent is called Concentration
- Solubility is The concentration of a saturated solution
- Solutes lower the freezing point and raise the boiling point of a solvent.
- Saturated Solution is a solution in which no more solid can be dissolved
- Unsaturated Solution is solution in which more solid can be dissolved
- Precipitate is a solid that crystallizes out of a saturated solution as it is cooled.

The correct answer is devastation by the pine bark beetle.
The pine bark beetles are very common pests, which are found on the pine trees of the Colorado. These beetle feed on the bark of the pine trees, which result in the loss of nutrition and trees becomes dead. In the given case, the attack of the pine bark beetle can be the reason for death of the pine trees and limiting factor to the population.
<u>Sediment</u> is formed as a result of interaction of igneous rock with wind and water over a long period of time.
<u>Explanation</u>:
An igneous rock is formed by the weathering of the molten earth material. If the igneous rock is continuously exposed to wind and water for long time then the fragments of the rock will get loosened. This causes the fragment to fall off and sediments will be formed.
Sediment is a material that is broken off from the rocks due to specific weather condition. As metamorphic rock requires high temperature or high pressure for its formation, it cannot occur with the interaction of wind and water.
