Answer:
1. Atmosphere ⇒ WESTERLIES
The atmosphere refers to the air surrounding a planet which is a mixture of gases the majority of which in Earth's case are Nitrogen and Oxygen. It is in the atmosphere that the westerlies occur. The westerlies are winds blowing from the west to the east.
2. Biosphere ⇒ GRAZING
The biosphere refers to the world's ecosystem and therefore includes all living and non-living things that the living things rely on for food. This is where grazing occurs as animals feed on plants.
3. Hydrosphere ⇒ TIDES
The hydrosphere refers to the waters of Earth including those on the surface, underground and airborne. Waves occur here on surface water.
4. Lithosphere ⇒ WEATHERING
The lithosphere refers to the surface of the earth that is made of rocks(land). Weathering, which is the process by which rocks are broken down, occurs here.
