What are the 4 spheres
Geosphere, Biosphere, Hydrosphere, and Atmosphere
Explain how we have night and day on earth.
The earth rotates and if the side of the earth that is facing towards the sun, that side of earth will have sunlight
What is the definition of latitude?
Latitude measureβs the distance north or south of the equator
What is the definition of longitude?
Longitude mesures the distance east or west of the prime meridian
What is the definition of coordinate
Coordinate is a measurement of an exact location on earths surface (in degrees)
About how long is 1 degree?
1 degree is about 111KM
Where does longitude meet?
The lines of longitude meet at the North and South pole
Do the lines of latitude stay the same?
Yes they do stay the same
Do the lines of longitude stay the same?
No they donβt stay the same
What is the northern hemisphere?
The half of the earth that is north of the equator. (From the equator to the North Pole.) It contains most of Asia, North America South America and Europe.
What is the southern hemisphere
The southern hemisphere is the area south of the equator. It contains Australia, Antarctica, 1/3 of Africa and some islands in Asia.
What is the eastern hemisphere?
The area east of the prime meridian and west of the international date line. It contains Asia, some parts of Europe and Africa.
Explain how we have seasons on earth.
The earthβs spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earthβs axis points towards the sun, it is summer for that hemisphere. When the earthβs axis points away, winter can be expected.
Axis definition:
An imaginary line which a body (earth) rotates on.
Coordinate definition:
A mesurent of an exact location on earths surface (in degrees)
What is the max degrees of latitude?
The max degrees of latitude is 90 degrees
What is the equator
An imaginary line drawn around the earth equally distant from both poles, dividing the earth into northern and southern hemispheres and constituting the parallel of latitude 0Β°.
What is the prime meridian
The earthβs zero of longitude, which by convention passes through Greenwich, England.
Why were time zones created?
Time zones are to align midday with the most sunlight around the world. So that people can have a standard time to be used for commercial and social conventions.
What is the Thermosphere?
Located between about 80 and 700 kilometers above Earthβs surface. Also known as upper atmosphere. The gases in this sphere are extremely thin. But they still become denser as you descend towards earth. The high energy of ultraviolet and x-ray radiation from the sun are absorbed by molecules in this layer and causing a significant temperature increase. The sphere is cloud-free and water vapor free.
How many degrees longitude in total are there in the world?
360ΒΊ
How many degrees (ΒΊ) does a time zone represent?
About 15 degrees
How many time zones are there in the world?
There is 24 time zones in the world
How much time does each timezone represent?
1 hour
When you move west, do you add hours or take away hours?
You take away hours, but gain more time (closer to AM)
When you move east, do you add hours or take away hours?
You add hours, but lose more time (closer to PM)
If its 2AM in England (GMT 0), what time is it in Toronto (GMT -5)
It would be 9 pm in Toronto
What are the 5 oceans?
Pacific Ocean, Atlantic Ocean, Indian Ocean, Arctic Ocean and the Southern Ocean
