The Coriolis Effect: The world is constantly rotating, making it impossible to go in a straight line directly to your destination.

An hemisphere is half of a globe with a circular flat base, a round edge, a curved surface but no vertices.
A rough rectangle may be drawn on a globe by drawing two lines of latitude, one just north and one just south of the equator that go halfway around the globe together, and then drawing a line of longitude around the globe, connecting their endpoints. Of course this will not produce a perfect Euclidean flat-sided rectangle because the surface is curved. Actually, this technique will make TWO very long rectangles, each with square corners, if all three lines are extended around the globe!
It depends on how complicated you want to make it. The generally accepted answer would be to start at one point, and make a line to the next (a straight line). That's gonna be the answer, say, your teacher might want (sorry if you're an adult :p). The technical answer? Drill a hole through the globe from one point to the other, and your shortest distance would be the straight line. Einstein's answer? A geodesic. Look it up :p
A globe.
Look at the route on a globe, the straight line route is actually longer.
It will roll around. To make a flat map from a round globe, a projection is used. In making the projection not all measures can be preserved and so distances will be stretched for some areas, and straight lines on the projection will correspond to curved lines on the globe. There are different projections that can be used which try to minimise the effect on different measures.
It is a sphere which looks like a globe

That phenomenon typically occurs when someone has sat on your globe.
The sky.
because it helps you see the shape of the continents. Globe, The curved shape is more like the real world so it is more exact.
An hemisphere is half of a globe with a circular flat base, a round edge, a curved surface but no vertices.
Maps allow you to see several areas of the surface at once and compare sizes, distances, etc. where a globe's curved surface obscures view and makes it difficult to look at a large area.
It is impossible for a flat map to be as accurate as a globe. The Earth is round and only a round globe can put things in the correct perspective.
Things, that we consider, are always within some limitations. Is that a small portion of the circle a straight line? However small portion that you consider on the circle, it would be, at least, slightly curved. Even then, we consider the small portion as a straight line. Same way, the region in which an insect crawling will be so small and that will be considered as a plane, hence two dimensional.
Because a straight line up and zooms right off the surface of the earth. Since the earth is a sphere (ball) only curved lines can stay on the surface. The meridian may not be a straight line, but it's the shortest possible distance between its ends, and you can prove it: The ends of the meridian are the north and south poles. Take a globe and a rubber band. When you stretch a rubber band between two points, it always follows the shortest path. Stretch the rubber band between the north and south poles of the globe. Make sure it goes across Green Which, and you'll see that it exactly follows the Prime Meridian.
