The physical environment can limit human activities in the following ways:
- Barriers to communication and transportation: most times roads have to be cut through longer distances in order to bypass natural features like a huge mountains, a voluminous river e.t.c. This can severely impact the communication between places and people.
- Natural disasters: The physical environment can pose serious risk to humans through disasters such as earthquake, landslide, flooding, wildfires, e.t.c.
- Drought and famine: When several elements of the physical environment combines, they can lead to little to no rainfall for plant to thrive. This is very dangerous for life on earth. Human activities are connected a lot to how rich and useful a soil can be.
- Climate changes and global warming: Human activities are greatly impacted by changes in climate and weather.

The external crust of the Earth consists of a series of tectonic plates moving on the planet's surface. Often volcanoes are created in regions where the plates come together. Volcanoes also can grow in the middle of a rock, which is named "Hot Spot," where the magma rises up until it bursts on the sea floor. A hot spot in the center of the Pacifical Rock is created on the Hawaiians Islands. The plate shifts, while the hot spot remains set. So the chain of the islands that comprise the Hawaiian Island chain was formed when this plate moved over the hot spot.
