answers verified to pass
geosphere - correct answer ✔rocks
solid earth
use for construction
three layers
hydrosphere - correct answer ✔cryosphere - ice
waters in river, oceans, lakes
atmosphere - correct answer ✔the envelope of gases surrounding the earth
biosphere - correct answer ✔life: plants, animals, microbes
science - correct answer ✔study of processes around us
systematic method that is not subjective but on facts
start out with data and observations
characteristics of good science - correct answer ✔tentative
predictable and testable
results have to be reproducible/ repeatable
natural causal mechanisms
1. prelminary observations
-facts, data
2. ask questions (data)
, 3. answer with hypothesis
-testable
4. hypothesis testing (experiments)
5. leads to theory
deductive reasoning - correct answer ✔used a general principal to reach
conclusion
inductive reasoning - correct answer ✔draw general conclusions from
specific examples
Every tornado I have ever seen in the United States rotated counterclockwise,
and I have seen dozens of them.
We see a tornado in the distance, and we are in the United States.
I conclude that the tornado we see right now must be rotating
counterclockwise.
earth in space - correct answer ✔energy that drives the earth comes from
outer space
age of the universe - correct answer ✔distance to the furthest object
v=λf=λ/T
brightness and luminosity of the stars
Dopple effect - correct answer ✔red shift-closer to red farther away
electromagnetic waves
apparent frequency all waves
apparently changing frequency due to the motion of a sound source
