Vocabulary 2.1
A unit used to measure distances around a circle
What is degrees?
The three main types of landforms
What are mountains, plains and plateaus?
The shape and steepness of the landscape
What is topography?
How many lines of longitude occur in the eastern hemisphere?
180
A sphere that represents earth's entire surface
What is a globe?
One half of the sphere that makes up Earth's surface
What is hemisphere?
Explain the latitude in this notation:
35° N
35 degrees north of the Equator
In topography, the measure of the steepness of the land
What is slope?
On topographic maps, every ___ line is normally darkened and given the height.
5th
A force of attraction between objects that is due to their masses
What is gravity?
The distance in degrees north and south of the equator
How many lines of longitude occur on the entire globe?
360
The difference in elevation between the highest and lowest parts of an area.
What is relief?
Explain the latitude and longitude in this notation:
45° S
87° E
87 degrees east of the Prime Meridian
A feature of topography formed by the processes that shape Earth's surface
What is a landform?
A framework of lines that helps in transferring points on Earth's three-dimensional surface onto a flat map
What is map projection?
A group of mountains closely related in shape, structure and age.
What is a mountain range?
A map showing the detailed shapes of the earth's surface, along with its natural and human-made features.
What is a topographic map?
If the top of a topographic map has lines (or "railroad tracks") through the closed loop, is it at the top or bottom of the structure?
Bottom
A landform made up of nearly flat or gently rolling land with low relief and low elevation
What is a plain?
A true cylindrical map projection; is useful for navigation because it maintains accurate direction, but makes the top and bottom of map seem distorted.
What is Mercator Projection?
Ranges and systems form larger unit
What is a mountain belt?
On a topographic map, a darker, heavier contour line that is usually every fifth line and that indicates a change in elevation.
What is index contour?
What is the advantage and disadvantage of the Mercator Projection?
Advantage: parallel grid lines on flattened map
Disadvantage: size and shape of landmass near poles is greatly distorted
The mostly solid, rocky part of the earth; extends from the center of the core to the surface of the crust.
What is a geosphere?
