Answers
Answer:
a) In simplest terms, water makes up about 71% of the Earth's surface, while the other 29% consists of continents and islands.
b) The Earth is an irregularly shaped ellipsoid.
While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid.
c) The roughly spherical shape of the Earth can be confirmed by many different types of observation from ground level, aircraft, and spacecraft. The shape causes a number of phenomena that a flat Earth would not.
d) the line where the earth and sky appear to meet
e) The atmosphere is comprised of layers based on temperature
f) There are 7 continents which include: North America, South America, Europe, Africa, Antarctica, Asia and Australasia. There are 5 oceans which include: Pacific Ocean, Atlantic Ocean, Arctic Ocean, Indian Ocean and the Southern Ocean.
g) Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth's shadow hides the Moon from view.
