Earth Science – a blending of many different sciences, including geology, meteorology, oceanography, and astronomy
Geology – the study of the materials that make up Earth- the study of Rocks
Meteorology – the study of the air that surrounds our planet
Astronomy – the study of objects beyond Earth’s atmosphere- the study of Space
Lithosphere – rigid outer shell of the planet, including the crust and the uppermost part of the mantle
Hydrosphere – all of Earth’s water, 97% exists as salt water
Most freshwater is contained in glaciers, very little fresh water exists as liquid on the Earth’s surface
Atmosphere – blanket of gases that surround our planet 78% Nitrogen, 21% Oxygen, 1% - H2O(v), argon, CO2, and other gases
Biosphere – all organisms on Earth and the environments they live in, most organisms live within a few meters of the earths surface
Scientific Method –ObservationQuestionHypothesisPredictionExperiment / TestAnalysisConclusion
Measurements – scientific experiments involve making measurements. The System International of Units or SI for short is the standard system of units used
Length – Meter (m)Volume – Liter (l)Weight – Gram (g) Temp – Degrees Celsius (oC)
Common Prefixeskilo = 1000 or 103centi = 1/100 or 10-2 milli = 1/1000 or 10-3
Scientific Notation – a form of shorthand to express very large and very small numbers
Number will be expressed as a value 0 thru 10 multiplied by a power of 10.
Number less than 1 get a negative power 3.0 x 10-3 = 0.003Numbers greater than 1 get a positive power 3.0 x 103 = 3000
