Global: MONOTHEISM TEST TOMORROW; STUDY.

WORLD RELIGIONS TEST 11/25

For those of you in my ES class with Mr. Donahoe, get your very own "one of a kind" 1st addition printed

"I heart ES sticker." You'll be the envy of all your friends with this colorful sticker slapped on your ES notebook

Latitude lines go around the Earth (like a belt) and measure distance in degrees north and south of the equator
They are also called parallels because they run east and west
parallel to the equator.
- equator = 0° latitude
- north pole = 90° north latitude
- south pole = 90° south latitude
- each degree is divided into 60 minutes
- each minute is divided into 60 seconds

Longitude lines measure distances in degrees east and west of the
Prime Meridian in Greenwich, England.
- Meridians run from the north pole to the south pole.

Prime Meridian = 0° Longitude
½ way around earth = 180° Longitude
North America is west of England, so we sit in an area of
west longitude
- Divided into minutes and seconds like latitude.

Parts of A Topographic Map
A. Topographic maps must show landforms on the earth’s surface.

B. Contour lines on topo maps connect points of equal elevation.
- a series of concentric circles general means a hill or
mountain at a location
1. Contour lines close together indicate a steep slope
2. Contour lines farther apart indicate a gentle slope
3. Contour lines show us the shape of the land at various
elevations

C. Contour interval is the change in elevation from one contour line to
the adjacent one. It can be anywhere from 5 to 100 feet.

D. Depression contours have small hash marks pointing downhill.
They generally indicate the presence of a hole or volcanic crater.
