What is the abbreviation for dekagrams?
Dag
Why does water vapor condense as it rises in the atmosphere?
Warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.
What are the individual lines of longitude called?
Meridian
What is the current level of atmospheric CO2?
416.30 ppm
Which branch of earth science involves the study of rocks?
Geology
List all metric prefixes from Mega -micro
Kilo, hecto, deka, centi, deci, milli, micro
What is an aquifer?
It is a body of rock and/or sediment that holds groundwater.
What is the difference (in degrees) between the equator and the North Pole?
90 degrees North
What time is in Spain when we have 10 AM if you know Spain is 1050E from us?
+7 hours = 5 PM
1050/150=7
List the branches of Earth Science
Geology, Meteorology, Astronomy, Oceanography-hydrology, Environmental Science
Convert: 0.0234 dL to hL
0.0000234 = 2.34x10-5
During the process of photosynthesis, what molecule is the Carbon CO2 incorporated into?
Into plant tissues
What line exists at 23.50 S?
Calculate the volume of a 23.4 g sample of iron with a density of 7.874 g/cm3
Density = Mass/volume (g/cm3)
7.874 g/cm3 = 23.4 g / volume
Volume = 23.4 g / 7.874 g/cm3 = 2.97 cm3
A scientist performs an experiment to determine if the amount of Sulfur emitted by burning coal is related to the age of the coal. She burns 15 samples of coal (100 gr each)of varying age from 200 million to 350 million years old and measures the amount of sulfur emitted. When she graphs her results, what should be plotted on the Y axis?
Amount of Sulfur emitted

Diagram the carbon cycle labeling all steps
Photosynthesis – CO2 goes into plant tissues
Consumption – animals eat carbon in plants
Respiration – animals and plants give off CO2
Decay – Carbon from dead organisms goes into soil
Combustion – CO2 released from burning organic matter and fossil fuels
