Earth Science Mapping Review
Latitude measures ___________________________
North and South of the *EQUATOR*
Longitude measures _________________
East and west of the *Prime Meridean*
Will latitude lines ever intersect?
No, they are parellel to each other
Do longitude lines run parallel to each other?
No, they're distances are very close at the Northern and Southern parts of the word than they are if they are towards the center.
Can you see Polaris if you are at the latitude 12 degrees South?
If I were to stand at the latitude 29 degrees North, how high in the sky is Polaris?
Polaris will be 29 degrees from the point where I stand. Remember that the angle of Polaris will always equal to the degrees of Latitude.
How high do Latitude lines go up to?
Latitude lines go up to 90 degrees North and South
What is the highest measurement that you can get for a Meridean?
180 degrees (the International Dateline)
What are Longitude Lines called?
Degrees of Latitude and longitude are broken up into smaller pieces called _______ with ______ in a degreeand then those are broken down to ________ with ______ in one _______.
Minutes, 60, Seconds, 60, Minutes
In one hour, the Earth rotates ___ because 360 degrees/24 hours = _____
15 degrees. Fun fact, the Earth rotates at 75 miles per hour!
There are 24 time zones on Earth, and each is ____ degreees apart
Every 15 degrees of longitude, your time changes by __ hour(s)
If it is 4:00 P.M. at 45 degrees West, what time should it be at 75 degrees East?
It is midnight of the next day
If it is 10:00 A.M. at 60 degrees East, what time should it be at 105 degrees West?
It is 11 P.M. the day before.
Contour Lines always point!!!_____________!!!
What direction is this river flowing? How do you know/
This river is flowing South (Southeast). I know because rivers always flow downhill, Rivers always flow to the ocean, and contour lines always point upstream
Find the elevation of point D
Be sure that you can draw profiles! Just like these two... Match up the paper to measure distance and label the elevation of every contour line. Then, graph it on the graph and make sure that the elevation is labeled correctly
Moving on then...
How would you find the gradient of a slope?
First measure the distance, then measure the elevation change, and divide the change in elevation by the change in distance
How can you tell what side of a hill is steepest?
The contour lines will be closest together.
In case of an emergency of a flood in a city, what actions could you take to protect the people and property?
