Q.How many continents of the world?
Ans. A continent of Earth's seven main divisions of land.
North America,South America,Europe,Africa, Asia, Australia,Antarctica,
Q. How many oceans are in the world?
Ans. Ocean :
A large body of water constitutes a principal part of the hydrosphere (The, Arctic, Atlantic, Indian, Southern, and Pacific oceans.)
There are Seven oceans in the world.
Arctic,
North Atlantic,
South Atlantic,
North Pacific,
South Pacific,
Indian,
Southern oceans.
Equator:
An imaginary line around the Earth divided the Earth Into two equal parts. “The Equator is a boundary between the northern and Southern hemispheres.
Q.What is latitude and longitude?
Latitudes
(Shown as horizontal lines ) is the angular distance, in degrees, minutes, and second of a point north or south of the Equator. These are the imaginary parallel lines around the Earth in the east-to-west direction lines that run east-west are known as lines of latitude,
Latitudes are horizontal lines that measure distance north or south of the equator.
Longitudes
Longitude is measured by imaginary lines that run around Earth vertically (up and down) and meet at the North and South Poles.
Longitudes are vertical lines that measure east or west of the meridian in Greenwich, England has a longitude of 0 degrees.
The lines running north-south are known as lines of longitude. These lines are known as meridians. Each meridian measures one arc degree of longitude.(Shown as vertical lines) is the angular distance, in degrees, minutes, and second of a point east or west of the Prime (Greenwich) Meridian.
Q.What are the 2 main lines of longitude?
1. Prime Meridian = Longitude 0o (Greenwich Meridian)
In the prime Mediterranean, I combine seven and a half degrees East and seven and a half degrees West, now it becomes fifteen degrees or the one-time zone is now15 degrees.
2. International Date Line (Longitude 180o).
Q. 1 Why is that international dateline there in the first place?
The international date line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway around the world from the prime meridian — the 0 degrees longitude line in Greenwich, England.
Q. Where is the Location of the International Date Line on the map?
Ans. The International Date Line is located halfway around the world from the Prime Meridian, and roughly follows the 180 degrees longitude line. It runs down the Pacific Ocean, in between Alaska and Russia, and down between Hawaii and New Zealand.
Q. 2 why isn't it straight so look at a map and there you can see the international date line and it isn't straight?
Ans. firstly just some background in case some of you didn't know this international dateline is the dividing line between two consecutive calendar days so on this side of the line, it might be Wednesday, and on the other side of the line Thursday. so in other words, if we are just to the right of this dateline and it's four o'clock on a Wednesday afternoon then if we cross that line then it will be four o'clock the next day Thursday on the other side of the line so here is the fact that it is possible to switch over three times between two consecutive calendar days by flying in a straight line so how's this possible let's have a look if you look at a map and if you're on a plane and you're flying a straight line between those two points if you start at point a where it's Wednesday if you fly straight you'll cross the line and you will enter Thursday if you keep going straight you will cross the line again and you'll be back into Wednesday and then you just keep going you cross the line again and it will be Thursday. The international date line goes from the north all the way down to the south pole and here we see Australia these Asian countries are there to the west of the line and to the east. we have north and south America.
