The Earth Beneath Our Feet
Hottest Layer of the Earth
Inner Core
What is the most common gas in the atmosphere?
Nitrogen
Any water that falls on the streets of Baltimore that does not get absorbed will end up in the __________ ________, then the Chesapeake Bay, then the Atlantic Ocean.
Baltimore Habor
True or False: The earth has had multiple ice ages over the last million years.
True
What is the name of the chemical in the stratosphere that protects us from harmful UV radiation?
Ozone
What layer is solid and the thinnest layer?
Crust
This layer of the atmosphere has the most density of gas and most weather events.
Troposphere
Name 2 pollutants that make it hard for fish to survive in our Harbor.
PCBs
Trash
Sediments
Salt
Fertilizers
Metals
Earth is technically still in one of these since there are still glaciers covering parts of the Earth.
Ice Age
Mid ocean ridges like the one in the Atlantic are formed at this plate boundary.
Divergent
What kind of land features are formed when an oceanic plate collides with a continental plate besides just mountains and earthquakes?
Volcanoes
What form of heat transfer lifts hot air into the upper atmosphere, where it is cools, and sinks back to the surface?
Convection
What is the name of our watershed that we share with 9 major rivers and states like New York, Pennsylvania, Virginia, and West Virginia? Named after the water body they all flow into.
Chesapeake Bay Watershed
What term describes how reflective a surface is, such as snow, which would have a high rating due to its ability to reflect heat and light.
Albedo
Methane and Nitrous Oxide are the second and third most influential _______________ _______ trapping heat and warming the Earth
Greenhouse Gases (GHGs)
This layer of the Earth is responsible for our protective magnetosphere thanks to its molten, liquid motion.
Outer Core
This gas makes up less than 0.05% of our atmosphere but accounts for 80% of all heat trapping in our atmosphere.
Carbon Dioxide
Who was the only institution in violation of EPA pollution dumping laws in our part of Baltimore?
Johns Hopkins Hospital
This greenhouse gas will lower in atmospheric concentration during ice ages since there is less biotic activity on land and in the oceans.
Carbon Dioxide
The _____________ is the upper part of the Mantle, and flows in a convection current causing our plates to shift around.
Asthenosphere
This type of plate boundary produces no mountains, no new crust, but can still cause devastating earthquakes.
Transfrom Boundaries
This form of heat transfer occurs on Earth at night when the heat energy absorbed by the ground during the day is directly transferred into the lower atmosphere.
Conduction
I will also take radiation but that is only after it leaves the surface and keeps traveling.
Identify something biotic that can prevent runoff before it enters the harbor.
Plant life!
What is one of the main reasons for climate change in Earth's history before humans evolved and altered the environment?
Changes in Earth's Rotation and Tilt
This atmospheric gas is fixed by bacteria in our soil, which plants then use to build new cells, DNA, and proteins.
Nitrogen
