wind blowing from land caused when heated air over water rises and air from land moves to replace rising air
🗑
|
||||
| Climate |
The average weather conditions over many years
🗑
|
||||
| Striations |
A groove or scratch on the surface of a rock, caused when boulders and gravel at bottoms of glaciers are dragged along rock surfaces
