Glossary of Terms. Bronchus / Bronchi / Bronchioles. The airways of the lungs. When a person takes in a breath of air, the air travels through the nose or mouth, into the larynx, then into the trachea, which is the main passageway into the lungs. The trachea divides into a right and left main bronchus.
Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. There are two types of weathering: mechanical and chemical.
Weathering and Erosionâ. Key Ideas. â¢ Weathering is the wearing away of the surface of rock, soil, and minerals into smaller pieces. â¢ Example of weathering: Wind and water cause small pieces. of rock to break off at the side of a mountain. â¢ Weathering can occur due to chemical and mechanical. processes. â¢ Erosion is the movement of particles away from their. source. â¢ Example of erosion: Wind carries small pieces of rock away. from the side of a mountain.
