| Question | Answer |
|---|---|
| The 5 branches of Earth Science. | -Geology -Oceanography -Meteorology -Astronomy -Environmental Science |
| Astronomers | -study the universe beyond Earth -starest planets -life cycle of stars -launch satellites and probes |
| Meteorologists | -study Earth's atmosphere and weather -study the air that surrounds Earth -study process of weather -study storms -predict hurricanes and tornadoes |
| Oceanographer | -study the oceans *oceans cover 75% of surface* -study ocean plants and animal life -study physical and chemical properties -study effects of human activity -map ocean floor -locate minerals |
| Geologists | -study Earth's surface, interior & history -study's Earth's materials and the processes that change them. -Minerologist: studies minerals -Hydrologist: studies water on surface, below surface &water pollution -Paleontologist: studies fossils |
| Volcanologists | studies volcanoes |
| Seismologists | studies earthquakes |
| Environmental Scientists | -studies Earth's environment and resources -study water pollution -study air pollution -study global warming -study the green house effect -studies the ozone layer -study effects on Earth's systems |
| Ecology | The study of the relationships of living things to their environment. |
| Biosphere | All organisms on Earth as well as the environments in which they live. |
| Lithosphere | Includes crust and upper mantle. |
| Hydrosphere | Water in Earth's oceans, seas, lakes, rivers, glaciers, and atmosphere. |
| Atmosphere | Gases surrounding Earth, including 78% nitrogen and 21% oxygen. |
| Structure of the solid Earth | -crust -upper mantle -mantle -outer core -inner core |
| Lab Safety | -be organized -cooperate with lab group -be cautious -be aware of surroundings -be attentive at all times -don't rush work |
| Lab Equipement | petri dish, fire extinguisher, test tube holder, funnel, watch glass, test tube rack, hot plate, safety goggles, fume hood, ring stand, pipette, eye wash station, graduated cylinders, beaker, erlenmeyer flask, corks, test tube brush, shower, test tubes |
| dropper, bunsen burner, stirring rod, triple beam balance, striker, spatula, rubber stopper, thermometer, motar and pestle, gloves, pasteur pipette, wire gauze & metal ring | |
| Scientific Method | Steps: 1. State the problem 2. Research the problem 3. Make a hypothesis 4. Write the procedure 5. Perform the experiment 6. Observe and record results 7. Interpret the data 8. State the conclusion |
| Control and Experimental Groups | Control Group: the group with no variables affecting them. Experimental Group: Being tested with variables being changed. |
| Remote Sensing | The process of collecting data about Earth from far above Earth's surface. |
| Landsat Satellite | Receives reflected wavelengths of energy emitted by Earth's surface. |
| Topex/Poseiden Satellite | Use radar to map features on the ocean floor. |
| Global Positioning System (GPS) | A radio navigation system that allows its users to determine their exact position on Earth. |
| Density | Density= mass/volume, Measured in (g/cm3) or (g/mL) |
| Volume | Volume= lenghth x width x height, Water displacement in a graduated cylinder. Measured as (cm3) or (mL) |
| Mass | Measure on a balance in grams. |
| Metric Units | Kilo Hecto Deca Meter Deci Centi Milli (km) (hm) (dam) (m) (dm) (cm) (mm) (kl) (hl) (dal) (l) (dl) (cl) (ml) (kg) (hg) (dag) (g) (dg) (cg) (mg) |
| Converting Units | KHDMDCM...move decimal place how many places each unit is from one another. |
| Scientific Notation | Use beginning number, x10, to the power of how many places to the decimal point. Examples: 90,000,000,000= 9x10^10 5,974,200,000,000= 5.9742x10^12 |
| Technology | |
| Frequency | Number of waves that pass a given point each second. |
| Wavelength | |
| Theory | An explanation based on many observations during repeated experiments. |
| Graphing |
