Ch 1 - Intro to Earth Science Review
Question | Answer |
---|---|
What are the topics studied in Earth Science? | Earth's atmosphere, Earth's surface, Earth's neighbors in space, Earth's interior |
geology | the study of Earth |
hydrosphere | the water portion of Earth |
atmosphere | an envelope of gases that surrounds Earth |
Biosphere | Includes all life on earth |
Oceanography | Study of composition & movements of sea water |
Meteorology | Study of the atmosphere & how weather forms |
Astronomy | Study of the universe and our origins |
Latitude | A distance measured in degrees north or south of the equator; lines run west to east |
Contour lines | Elevation is shown on a map using contour lines |
System | Can be any size group of interacting parts that form a complex whole |
Equator | The line that marks zero degrees latitude |
Prime meridian | Line that marks 0 degrees longitude |
Geosphere | Beneath the atmosphere |
Core | Hot dense center of our planet |
Crust | Very thin 3-5 miles |
Topographic map | Shows Earth’s three-dimensional surface in two dimensions showing the elevation status |
Tropic of Cancer | 23° north latitude |
Globe | A round shaped representation of the earth |
Internal and external | Rock and minerals form in response to Earth's _____ and _____ processes |
mantle | located below the Earth's crust and above the Earth's core |
longitude | the distance east or west of the prime meridian, measured in degrees; lines run north to south |
northern and southern | equator divides Earth into two hemispheres |
eastern and western | prime meridian and the 180 degree meridian divide Earth in to two hemispheres |
equator | The 0° line of latitude is the starting place of measuring latitude |
contour interval | the difference in elevation between adjacent contour lines |
geologic map | shows the type and age of exposed rocks |
system | any size group of interacting parts that form a complex whole |
closed system | matter does not enter or leave the sytem |
open system | energy and matter flow into and out of the system |
sun and Earth's interior | two sources the power the Earth's system |
Environmental science | focuses on the relationships between people and Earth |
renewable resources | resources that can be replenished over relatively short time spans |
air pollution, acid rain, ozone depletion, global warming | significant threats to Earth's systems/environment |
4 major spheres | hydrosphere, biosphere, geosphere, atmosphere |
maps | shows a flat representation of Earth's surface |
physical and historical | two broad areas which geology can be divided into |
physical geologists | examine materials made up from Earth |
Earth Science | name of the group of sciences that deal with earth and its neighbors |
tropic of capricorn | 23 degrees south latitude |
90 degrees | the number of degrees there are from the equator to the north or south pole |
longitude lines | which lines meet at the poles? |
