B. Answer the following questions. 1. What is a globe ? How is it used ? 2. Define the term'latitude'. Mention some important latitudes. 3. What are the characteristics of longitudes?
Answers
In geography, latitude is a geographic coordinate that specifies the north–south position of a point on the Earth's surface. Latitude is an angle (defined below) which ranges from 0° at the Equator to 90° (North or South) at the poles. Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude is used together with longitude to specify the precise location of features on the surface of the Earth. On its own, the term latitude should be taken to be the geodetic latitude as defined below. Briefly, geodetic latitude at a point is the angle formed by the vector perpendicular (or normal) to the ellipsoidal surface from that point, and the equatorial plane. Also defined are six auxiliary latitudes that are used in special applications.
Answer:
ans 1. a globe is a 3 dimensional sphere used to represent the earth as a whole.
Explanation:
it is used to search for various nations and oceans.
Ans.2. the distance of a place north or south of the line that we imagine around the middle of the earth. the equator 0° , tropic of Capricorn 23.5° north ,
the Tropic of Capricorn (23.5° south)
the Arctic circle (66.5° north)
the Antarctic circle (66.5° south)
the North Pole (90° north)
the South Pole (90° south
ans.3. Characteristics of Longitudes
Each meridian is half of a great circle.
They run in a true north-south direction from. connecting the North and South Poles.
They are spaced farthest apart at the equator but. converges at the poles.
Meridians help us to determine standard time.
