Answer:
Elevation
Index contours
Contour interval
Explanation:
Contour lines on topographic connect points of equal elevation on the earth crust.
They are used to delineate the elevation of the landforms in an area.
Index contours are heavier lines on the topographic maps. They have numbers for specific elevation. The elevation of the index contour is used in extrapolating those of other places on the map.
The difference in elevation between contour lines is called contour interval. Most maps usually have consistent contour interval.
Answer:
<u>Landslides deposits, shallow faults and sedimentary marks.</u>
Explanation:
- This place is located in mid-Atlantic, is located at the border of Hudson canyon which is a zone of a seismic event. The data collected from USGS in 2018 shows the gas deposits and structural features beneath the seafloor.
- The USGS data show the gas hydrates that were obtained from the sea bottoms. The hydrate interacts with the environment and the formation of geohazards like submarine landslides.
- Thus these places on the map receive the methane sweeps and hydrates of gas coming from the tectonic plate from below. The name of the edges of the shelf is also given after the submarine canyons.
The answer is either B or D. Letter A doesn't make sense and letter C isn't right either because you need rainfall to have fertile plains.
