MAPS
MAPS ARE PRIMARY TOOLS ELEMENTS Scale: Explains the relationship of the data frame extent to the real world. Projection: -Cylindric -Pseudocylindric -Conic -Planar 3.Symbols TYPES General Reference: Natural & man-made feautures in an area. *Transit map *Topographic map *Political map Thematic: Identifiable earth surface features informational description over an area, rather than a data surface. Physical map Climate map Land use map Population map
IMAGINARY LINES
馃寧馃挮 What are the 5 imaginary lines on Earth?馃挮馃寧 Equator: This is the king of all imaginary lines. Prime Meridian: This line marks zero degrees longitude, and is actually quite arbitrary. Tropic of Capricorn. Longitude. Tropic of Cancer.
MAGNETIC FIELD
What does the magnetic field mean? Definition: A magnetic field is a force field created as a result of the movement of electric charges (flow of electricity). The strength (intensity or current) of a magnetic field is measured in Gauss (G) or Tesla (T). The flux decreases with the distance to the source that causes the field. How does a magnetic field work? Magnetism is a physical phenomenon by which objects exert forces of attraction or repulsion on other materials. The only known natural magnet is a mineral called magnetite, however, all materials are influenced, to a greater or lesser extent, by the presence of a magnetic field. HOMEMADE COMPASS Our planet acts like a giant magnet, creating a magnetic field that shields Earth from radiation from space. Magnetized metals naturally align with that field, and one can take advantage of that invisible effect in the experiment that shows us how to magnetize a needle to create a compass. What we need? A sewing needle A cork or plastic c
