Magnetic striping is evidence of seafloor spreading.
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.

Hello. You didn't show the map or say what kind of map the question is referring to, which makes it impossible for the question to be answered. However, I can help you by showing you what data you can see on different types of maps.
On physical maps you can see data on the relief of a region, data on the distribution of cities in a region and data on the existence of rivers, caves, mountains, forests and other elements that can compose that region.
On economic maps you can see data related to the economic activities of a region, data on the establishment and distribution of trade in a region and you can see statistical data on the economically active population in the region.
In demographic maps you can look at migration data, data about the spatial distribution of people in a region and you can analyze rates (illiteracy, birth, mortality, among others).
On political maps you can see data about the geographic borders of a country, or cities and states, data about the extension of territories, and data about political borders.
In historical maps you will be able to observe data about an event that was established during a period of time, data that portray the distribution of territories in a region and data of colonial advance in the continents.
Answer:
Brazilian Highlands
Explanation:
The Brazilian Highlands are a vast area of Brazil that include not only jungles to the west but also the Atlantic forests to the east. These latter forests have been drastically reduced in the past decades and now less than ten percent of their original extension remains.
The western reaches of the Highlands border the Amazon and also experienced deforestation to the expansion of farms and also of land used for cattle ranching. Another factor that rapidly accelerates deforestation in the region is the expansion of urban areas.
