The Great Plains have a continental climate. Over much of their expanse, cold winters and warm summers prevail, with low precipitation and humidity, much wind, and sudden changes in temperature. The major source of moisture is the Gulf of Mexico, and the amount falls off both to the north and west.
Answer:
Earthquakes are caused by fault lines.
Explanation:
The continents are on massive tectonic plates the are constantly shifting because of the movement of magma underneath them. When the tectonic plates rub against each other, or collide with each other, it creates movement that we know as earthquakes. The reason why we feel earthquakes is because of the sudden energy release which causes seismic waves. One famous fault if the San Andreas fault, located in California. That is the reason why earthquakes are common in California (because it is located right next to a fault line).
Answer:Syncline
Explanation:A syncline is a fold in which the youngest rocks occur in the core of a fold (i.e., closest to the fold axis), whereas the oldest rocks occur in the core of an anticline.
A fold of rock layers that slope upward on both sides of a common low point. Synclines form when rocks are compressed by plate-tectonic forces. They can be as small as the side of a cliff or as large as an entire valley.
Synclines are formed when tectonic plates move toward each other, compressing the crust and forcing it upward.
