Answer:
There are lots of data sources available for map makers online. These data sources provides information on satellite imagery, topographical surveys, aerial photography, populations,natural features, etc. The information they provide is vital for the accuracy of a map. Some of these sources are;
- <u><em>Natural Earth</em></u>: A public free domain that provides cultural, physical and basemap data.
- <u><em>USGS Earth Explorer</em></u>: This data source provides an abundance of satellite and aerial imagery worldwide.
- <u><em>Open Topology</em></u>: Gives access to a high spatial resolution topographic data and tools like LiDAR (Light Detection and Ranging) Data.
- <u><em>UNEP Environmental Data Explorer</em></u>: This is a United Nations based data source. It provides useful data on population, forests, emissions, disasters and GDP of people and places.
- <u><em>Global Map Github</em></u>: provides useful data on boundaries, drainage, transportation, population centers, elevation, land cover, land use and vegetation of places on earth.
The answer is going to be c.
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:
They are deposits of silt and mud carried by the wind.
They are found in regions close to but outside areas of glaciation.
There are deposits in Europe, North America, China, and Argentina.
Explanation:
Loess was first discovered and coined in Europe and refers to an important component of the soils of the European Plain. Loess consists of particles of silt, clay, and mud that have been carried by the wind and eventually deposited to form extensive formations.
Loess layers are not only deep but also conducive to agriculture as they are also fertile. Perhaps the most common source of loess is the glacial activity since the movement of glaciers produces a large amount of finely ground sediment on the fringes that is later picked up by the wind.
