Hi!
A few things that have an impact on culture are:
- <em>mountains</em>
- <em>climate</em>
- <em>plains</em>
- <em>temperature</em>
- <em>deserts</em>
<em />
<em>Mountains </em>because if people live on mountains, it can be hard to farm, so they will have to adapt and figure out food sources.
<em>Climate </em>because, again, humans have to adapt to the climate. For example, if it's a dry, humid climate, they might make dirt houses to stay cool or wear certain clothes to stay cool.
<em>Plains</em> because, like mountains, they are different elevations. In plains, it may be dry and there may not be trees, therefore they will have to use the resources available to survive.
<em>Temperature</em> - for example, if it's super cold, people will most likely constantly be wearing jackets, boots, gloves, etc. There may also be a lack of food sources and they will have to adapt.
<em>Deserts</em> because, if people live in the desert, there will be a very limited amount of water. They may have to walk far to find some, and will have to adapt in other ways.
Hope this helps! :D
