L.O: REVIEW EARTH’SSHAPE, LATITUDE andLONGITUDE
The true shape of Earth is anoblate sphere.The earth is slightly flat at the polesand bulging at the equator.
The true shape is an oblatesphere, but from space pictures itlooks like a perfect sphere.
POLARIS the NORTH star is a starthat is ONLY seen in the northernhemisphere.
POLARIS IS DIRECTLY OVER THE NORTHPOLE..
ALL THE STARS APPEAR TO REVOLVEAROUND POLARIS AT A VELOCITY 15 PERHOUR.
THE TWO POINTER STARS ON THE BIGDIPPER POINT TO POLARIS ON THEEND OF THE LITTLE DIPPER.
In the northern hemisphere, POLARIS’altitude ALWAYS equals your latitude.
WHAT IS THIS OBSERVER’S LATITUDE?
52 DEGREES NORTH
AS your latitude INCREASES, thealtitude of Polaris ALSO INCREASES.
the CHANGE IN THE altitude of Polarisis evidence that Earth is round.
At the equator (zero degreeslatitude), Polar is at zero altitude.
At the north pole (90 degrees latitude)Polaris’ altitude is also 90 degrees.
What is one latitude if Polaris is at 45degrees?
One’s latitude is also 45 degrees N
On the regents, I will have todetermine the latitude andlongitudes of CITIES in NEW YORKSTATE and on other parts of EARTH.
FINDING THE LATITUDES OF NEW YORKSTATES CITIES IS EASY. I CAN USE THE MAPON PAGE 3 OF THE ESRT.• LATITUDES IN NEWYORK STAT...
ON THE REGENTS, I WILL HAVE TOFIND THE LATITUDE ANDLONGITUDE OF PLACES ON EARTH
THE IMPORTANT LATITUDESTHE EQUATOR LATITUDE IS ZERO.NORTH POLE 90 NSOUTH POLE 90 S.
LONGITUDE• EACH TIME ZONE IS 15 DEGREES WIDE.• EX: LOCATIONS WITH A 3 HOUR DIFFERENCEIN TIME ARE: 3 X 15 = 45 DEGREES APART.
