  • The air we breathe and all the gases in the air

    • Protects us from UV light

    • Produces all forms of weather


Geosphere

  • We will be able to determine where cities are on a map using latitude and longitude coordinates



Latitude
Latitude

  • Latitude – The distance north or south of the equator, measured in degrees.

  • LANS


Longitude
Longitude

  • Longitude – The distance East or west of the prime meridian, measured in degrees.

  • LOWE


Prime meridian equator
Prime Meridian / Equator

  • Equator – 0 degrees latitude

  • Prime meridian – 0 degrees longitude


On white boards
On White Boards

  • Using your definition, draw a globe with latitude lines.

Objective: Notes 1.3-1.5 (Pg 27)

  • We will be able to create a 3D map from a 2D topographic map.

  • We will be able to determine the elevation of certain features on a topographic map using contour lines and contour intervals


Topographic map
Topographic Map

  • Topographic Maps show Earth’s surface in 3 dimensions. They show elevation


How do topographic maps differ from other maps
How do topographic maps differ from other maps?

  • Topographic Maps show elevation.

    • Elevation means 3 dimensions

    • Most maps only show 2 dimensions.


Contour line
Contour Line

  • Contour Line – A line on a topo map that indicates elevation

  • Every point on a contour line is the same elevation.


Contour lines cont d
Contour Lines Cont’d

  • If contour lines are CLOSE together, that means the land is very steep.

  • If contour lines are WIDELY SPACED, the change in elevation is gradual.


Contour interval
Contour Interval

  • Contour Interval – The space in between contour lines.

  • The contour interval varies based on the map.


Explain the difference between a hypothesis and a theory
Explain the difference between a hypothesis and a theory

  • Hypothesis – A possible Explanation (untested)

  • Theory – Well tested and widely accepted by the scientific community


Examples
Examples

  • Theory of Gravity – Why we fall down

  • Atomic Theory – What we are made of

  • Theory of relativity – Einstein’s work

  • Big Bang Theory – How the universe was formed



What is a topographic map
What is a Topographic Map?

In contrast to most maps, a topographic map shows the shape of the Earth’s surface by using contour lines.


Contours are imaginary lines that join points of equal elevation above or below sea level.







We ve made it to 300m
We’ve made it to 300m!

On to the peak
On to the peak!

Any ideas
Any ideas?

Let’sadd contour lines for every 50 meters and see if that helps.

300m

200m

100m


We know that we are above 350m, but less than 400m.

350m

Let’s head down the hill, it’s getting late!

350m

300m

250m

200m

150m

100m

50m


Now what’s our elevation?

If you said somewhere between 200m and 250m you are right!

350m

300m

250m

Let’s try this again!

350m

What’s our elevation now?

If you said 50m or just under, you’re right!

350m

300m

250m

200m

150m

100m

50m


Let s now look at the same hill but the way we might see it from an airplane
Let’s now look at the same hill, but the way we might see it from an airplane!







Think you know our elevation now? your right!

More than 300meters

But less than 350meters


If we were standing on the peak what would be our elevation
If we were standing on the peak, what would be our elevation?

  • More than 350 meters, less than 400 meters




More than 100 meters, elevation?

less than 150 meters



Let s see what you know
