Answer:

At least three seismic stations

Explanation:

To determine an earthquake epicenter requires coordination between at least three seismographs. This is because a seismograph is only capable of registering the strength and amplitude of an earthquake; that is to a say, a single seismograph can register the occurrence of an earthquake. This describes a circle with the seismograph at the center. A second seismograph, which can be hundreds or thousands of miles away, can generate a similar plot. The circles from these two stations cross each other at two points. Finally, the third station points to the epicenter as the only place where all three circles intersect.

Answer:

It influence the way they conduct their daily activities and the types interaction that they have with other living near their environment.

Explanation:

The contrast between the cold winters and warm summers force the Native American to be smart when managing their hunting and agricultural activities.  They focused their hunting and farming during the warm summer as an  effort to accumulate enough food throughout the winters (since very few plants can grow and animal lives nearby when the weather is really cold).

The cold winters also forced them to find a reliable way to warm themselves to survive the temperature.

Both of these problems can be solved by using the animal remains. The meat provide them with nutrition for them to survive and the fur can be used to provide warmth and comfort.

This is why the concept of Spirit Animals are known among native American culture. They do it as a form of respect to them since the animals enable their tribe members to live.
