Answer:
The representative fraction of photo will be 1:3600
Explanation:
Orthophoto is constructed geometrically where there is no distortion unlike maps.
The width of a five lane freeway is 0.2 inches.
Assuming the width of each lane to be 12 feet, then the total width of all the five lanes is 12×5=60 feet
We know that 1 feet = 12 inches
So, 60 feet = 60×12= 720 inches
So , we get that 0.2 inches on the orthophoto is 720 inches on the ground.
So, 1 inch on the orthophoto = 
inches on the ground = 3600 inches.
Thus the scale is 1:3600
Answer:
Five accurate data sources map makers can rely on for map making are:
- Esri Open Data Hub
- Natural Earth Data
- USGS Earth explorer
- OpenStreetMap
- NASA's Socieconomic Data Centre
Explanation:
1. Esri Open Data Hub has over 250,000 open data sets from over 5,000 organizations worldwide, and is the largest GIS organization in the world. Data types found there are OGC, WMS, GeoJSON and GeoService.
2. Natural Earth Data is a public domain data source best suited for cartographers, and is supported by the NACIS. Physical and cultural raster data, quick start kits (MXD and QGS) files can be found there.
3. USGS Earth Explorer has worldwide satellite imagery and a state-of-the-art user interface. Landsat, Sentinel-2 and land cover, digital elevation models such as NASA's ASTER and STRM are data examples that can be found there.
4. OpenStreetMap possibly has the biggest inventory of buildings in the world, with highly detailed GIS data. High spatial cultural vector data such as buildings and waterways can be found there.
5. SEDAC has a gridded population of the world, including population characteristics, also Global socioeconomic data comes from 15 different themes. Data includes agriculture, climate and health.
Chile is stretched on the North-South Axis, but very thin on the East-West axis, or in other words: it's very long and very narrow.
Some problems connected to this are based on the large cost of transportation: the distances between the cities are very large and in fact, the southern part of Chile is only reachable from Argentina by land.

Answer : Option C, The sample will mainly consist of granite.
Explanation:
Sample collected from was continental crust (a part crust) as the samples were from 60 km deep. Continental crust ranges from 30 km to 70 km and this layer is mainly includes granite. This continental crusts is mainly responsible for formation of distinct land-forms like continents.
Statement A ,B and D informs us about the state and temperature of metals(iron) in core that is inner most layer of the earth.
Most of the population is Roman Catholic...
Culture is the customs, arts, social institutions, and achievements of a particular nation. Knowing that the majority is Roman Catholic we can assume their customs and social institutions.
I hope this helps! :)
