Answer:
looking for things frozen in glaciers can help determine what the climate was like thousands of years ago such as the amount of pollen and gas bubbles in a sample of ice
Explanation:
The number that Colorado River would have to downcut per year to form the mile-deep canyon in 4 million years is 0.40 millimeter per year.
Depth of canyon = 1 mile
Time taken = 4 million years
Based on the above information, the rate will be:
= Depth / Time taken
= 1 mile / 4 million years
= 0.25 mile / million year
Note tha<em>t 1 mile = 1609344 millimeter</em>
<em />
Therefore, the rate will be:
= (0.25 × 1609344) / 1000000 years
= 0.40 millimeter / years
In conclusion, the rate is 0.40 millimeter per year.

Answer:
The answer is below
Explanation:
The question is not complete since no map is attached, but I would show you how to solve it.
When trying to determine the location of the epicenter of the earthquake, we need at least three different seismic stations. To find the epicenter, a method known as triangulation is used. This is done by drawing circle at each of the seismic stations with the radius of the circle equal to the distance from the station to the earthquake. The point of intersection of this three circles is the epicenter.
In this problem, a circle with a radius of 380 miles is drawn at Phoenix, 280 miles radius circle at Denver and a 880 miles radius circle at California. The point of intersection of the circle gives the epicenter. Note that the circles are drawn to scale.

When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.
