Science Chapter 2 Section 1 & 2
| Question | Answer |
|---|---|
| Define Map | Representation of the features of a physical body such as Earth |
| Define Reference Point | Is a fixed place on the Earth’s surface from which direction and location can describe |
| What are two major reference points we can find on a map of the Earth? | North Pole South Pole |
| Give 2 other examples of reference points we might use. | Direction Location |
| Define Cardinal Directions | North, South, East and West, as well as combinations of these directionsExample: Compass |
| List the 4 cardinal directions | North South East West |
| Define compass | Shows the cardinal directions North, South, East and West, as well as combinations of the directions |
| What creates the Earth’s magnetic field? | The Earth's molton core |
| What is True North? | The direction to the geographic North Pole |
| What is Magnetic Declination? | The difference between the magnetic north and the true north |
| What is the Equator? | The imaginary circle half-way of the earth |
| Where is the Equator located? | Between the poles that divides the Earth into the Northern & Southern Hemispheres |
| Define Latitude | The distance north or south from the equator expressed in degrees |
| What is the Prime Meridian? | The meridian, or line of longitude that is designed as 0 degrees longitude |
| Where is it located? | Degrees longitude are a measure of the angle made by a prime meridian and the location on the earth’s surface, as measured from the center of the earth |
| Define Longitude | The distance east and west from the prime meridian, expressed in degrees (40) |
| What is the most accurate model of the Earth? | A map is a representation of the features of a physical body such as Earth |
| What does this model show? | What explores thought the world looked like 1800 years ago |
| What can’t this model show? | Observations |
| What are distortions? | Shapes as well as distances between points are distorted |
| What is a map projection? | To move the image of Earth’s curved surface onto a flat surface |
| Identify the 3 common shapes used for map projections | cylinder cones planes |
| Cylindrical projection | A map projection that is made when the contents of the globe are moved onto a cylinder of paper |
| What is a Mercator projection | it is a mathematical method of showing a map of the globe on a flat surface |
| Features distorted on a cylindrical projection | A map that is made by moving the features of the globe onto a cylinder |
| Conic Projection | A map projection that is made by moving the surface features of the globe onto a cone |
| Features distorted on a conic projection | Areas near this line are distorted less than other areas are |
| Azimuthal Projection | A map projection that is made by moving the surface features of the globe onto a plane |
| Features distorted on an azimuthal projection | Distoration of direction, distance and shape increases as youmove away from the point of contact |
| Equal Area Projection | A map projection that shows the area between the latitude & longitude lines the same size as that area on a globe |
| List the 6 pieces of information all maps must have | 1. Title2. Compass Rose3. Scale4. Legend5. Date6. |
| What is remote sensing? | Is a way to collect information about something without physically being there |
| Define GPS and what it is | Global Positioning System (GPS)Is a system of orbiting satellites that send radio signals to receivers on Earth |
| Define GIS and what it is | Geographic Information System (GIS)Is a computerized system that allows a user to enter different types of information about an area |
