Explanation:

1. Erosion is the process of wearing away of the earth's surface by natural forces like wind, water etc. Wind carrying sand from one place to another is an example of erosion. Lava cooling to form new rock is a process of rock - formation (igneous rock formation), earthquakes breaking apart the land is related to tectonic activity and condensation forming clouds is a part of the water - cycle.
2. The atmosphere is the layer of gases surrounding the Earth. All water on Earth is the hydrosphere, all landforms on Earth are part of the geosphere and the solid outer crust of Earth is also part of the geosphere.
