EARTH SCI 2GG3 EXAM SCRIPT WITH
VERIFIED QUESTIONS AND ANSWERS
●● *INTRO TO EARTH SCIENCE*
Answer:
●● 4 Main Branches of Earth Science
Answer: Geology, Astronomy, Meteorology, Oceanography
●● Geology
Answer: The study of the materials that make up the earth's surface
(Rocks, Minerals, Etc.)
●● Astronomy
Answer: The study of objects beyond the earth (Space, planets, stars,
meteors)
●● Meteorology
Answer: the study of the weather, climate and the atmosphere
●● Oceanography
,Answer: the study of the nearly 75% of the earth that is covered by
water
●● 3 Main Earth Systems
Answer: Lithosphere, Hydrosphere, Atmosphere
●● Lithosphere
Answer: the rigid outer shell of the earth (Crust)
Types: Oceanic/Continental
●● Continental Crust
Answer: -Less Dense (2.7 g/cm^3)
-Thicker
-Made of mostly granite
●● Oceanic Crust
Answer: -More Dense (3.0 g/cm^3)
-Thinner
-Made of mostly basalt
●● Hydrosphere
Answer: Water on in and around earth
,-97% is saltwater; 3% freshwater
●● Atmosphere
Answer: Layer of the gasses that surround the earth
4 Layers
1. Troposphere
2. Stratosphere
3. Mesosphere
4. Thermosphere
(R/T Pg. 1)
●● Observation
Answer: The use of 1 or more of the 5 senses to learn something about
the environment
-Problems: Accuracy- senses are limited
-Solutions: Use instruments to extend out senses
●● Classification
Answer: Group objects based on similar characteristics
-helps to organize
-makes studying and understanding easier
, ●● Inference
Answer: Logical conclusion/educated guess based on observations
-More observations=Better _____________
●● Frame of Reference
Answer: Something to compare to; the starting point
●● What are the 2 most common Frame of References?
Answer: Time and Space
●● Measurement
Answer: a comparison to a known standard
-2 parts to every measurement: Quantity and Unit
●● Metric System
Answer: SI= Systeme International
●● Quantities
Answer: Length, Mass, Volume
●● Units
Answer: Meter (m); Grams (g); Liters (l)
