Answer:
1. The nebular hypothesis suggests that our solar system evolved from a huge rotating cloud of dust and gas.
2.) Lines of longitude are used to measure distances east or west of the prime meridian in degrees.
3.) The major difference between a topographic map and other maps is that s topographic map shows elevation.
Explanation:
The nebular hypothesis is the most widely accepted hypothesis to describe the formation of the solar system. It states that the solar system born from a nebula, which is a cloud of atoms and molecules in the outer space.
Latitudes and longitudes are the units of the geographic coordinate system. Every address in the world has a set of coordinates, latitude, and longitude. Latitude divides the globe in north and south from the equatorial plane, while longitude divides the globe in west and east from the Greenwich Meridian.
A topographic map shows the topography. Although there are many methods, usually it has contour lines to indicate points with similar elevation.
