This is the nuclear process that creates new elements in the core of a star AND produces energy
Nuclear Fusion / Nucleosynthesis
100
New crust formation at ridges occurs at what tectonic plate boundary?
Divergent
100
How deep in the Earth does the Lower Mantle layer go?
2900 km
100
What is the present WEATHER CONDITION according to this weather station model? BE SPECIFIC
Steady, light rain
100
Identify two sources of Greenhouse Gases
Livestock/agriculture (farts), melting permafrost, burning fossil fuels, car exhaust, industrial emissions, etc
200
There are TWO main pieces of evidence that supports the Big Bang Theory, explain ONE
Red shift of galaxies supports the expansion idea of the universe, Cosmic Background Radiation
200
Identify a piece of evidence that supports the theory of continental drift and plate tectonics
Same fossils on different continents, land masses appear to fit together like a puzzle, same rock formations on different continents
200
In there are water cycle, there are 2 ways that water vapor can enter the atmosphere. Name one of these processes.
Evaporation and Transpiration
200
What is the difference between WEATHER and CLIMATE?
TIME! - Weather is short time atmospheric conditions, climate is long term (years, decades)
200
What is something we as humans can do do DECREASE the amount of greenhouses gases in the atmosphere that contribute to climate change?
Decrease emissions, limit or stop using fossil fuels,
300
What causes the seasonal differences on Earth?
TILT
300
What PERIOD of Earth's history did the first horses and whales evolve?
Paleogene
300
What agent of erosion formed this valley in the past?
GLACIERS (U-shaped)
300
What is an example of a weather event that is likely to occur in a LOW pressure system?
Rain, snow, hail, storms, tornado, precipitation, etc
300
Identify a NEGATIVE impact associated with global climate change
THERE ARE SO MANY (unfortunately)
400
Identify the star that is categorized as a "Main Sequence Star" with a luminosity value of 10.
PROCYON
400
What is the YOUNGEST event/feature here? Explain how you know.
E (fault) shifts all pre-existing rock units
400
Use the ESRT to answer this question. There are 6 minerals that are present in a sample of Granite. Name 2 of them
Quartz, Potassium Feldspar, Plagioclase feldspar, Muscovite, Biotite, Amphibole
400
What two-letter code would you assign to an air mass that is HUMID and WARM?
mT (maritime tropical)
400
How does the increasing CO2 concentration in the atmosphere impact shell-building organisms and coral colonies in the oceans?
Increased CO2 in the atmosphere increases CO2 in the ocean water, creating more carbonic acidic conditions in the water, dissolving or weaking the calcite used in the construction (OCEAN ACIDIFICATION)
500
According to the Solar System Objects Data Table in the ESRT, Mercury has the quickest Period of Revolution (orbit). Why is Mercury orbiting faster around the Sun compared to the other planets in the Solar System?
Mercury is closer, so the gravitational pull is stronger, making it orbit faster
500
How old is a rock sample containing radioactive Potassium-40 that has experienced 2 half-lives?
2.6 billion years old
500
What test can you do to differentiate similar looking minerals like Halite and Calcite?
Acid test (calcite reacts with acid), Salty taste of halite, hardness/scratch test, streak test,
500
Compare the climate conditions, in terms of MOISTURE content and TEMPERATURES of the Leeward side and Windward side of this mountain
Windward = high moisture and cooler
Leeward = dry and warmer
500
Explain how the warming of global temperatures creates a POSITIVE FEEDBACK LOOP with the Albedo Effect of snow and glacial ice
Increasing temperatures melt more snow and ice -> less solar radiation is reflected -> more darker earth surface is exposed -> more absorption of solar energy -> back to the beginning
