1. Geography affects the settlement of future civilizations when taking into account the resources provided in different areas. Lusher areas with a larger range of edible plants and animals as well as water are a very appealing location to start a settlement. Of course, different groups of people with different lifestyles will be searching for varying resources to start their society, or to just stay temporarily if they choose nomadic existence.
2. Climate majorly affects settlements depending on if they want to grow crops, as well as the type of crops. Another factor dealing with climate in relation to settlements is if it is a bearable climate to live in long term without higher death rates due to temperatures.

Answer:
Sometimes an entire ocean closes as tectonic plates converge, causing blocks of thick continental crust to collide. A collisional mountain range forms as the crust is compressed, crumpled, and thickened even more. The effect is like a swimmer putting a beach ball under his or her belly—the swimmer will rise up considerably out of the water. The highest mountains on Earth today, the Himalayas, are so high because the full thickness of the Indian subcontinent is shoving beneath Asia.
The Appalachian Mountains formed during a collision of continents 500 to 300 million years ago. In their prime they probably had peaks as high as those in the modern zone of continental collision stretching from the Himalayas in Asia to the Alps in Europe. But over the past 300 million years, the Appalachians have eroded to more modest heights.
