radiation
|
The heat transfer of energy through empty space. there is no didrect contact between heat sourse and an object (sunlight)
|
|
heat transfer
|
Movement from a hot object to a cool object
|
|
Basalt
|
a rock that makes up much of the ocean floor. A dark dense igneous rock with a fine texture found in the oceanic crust
|
|
Asthenosphere
|
A soft layer of the mantle on which the lithospere floats
|
|
Crust
|
A layer of rock that forms earth outer surface. It is much thinner than the layer that lies beneath it. (like an onion skin)
|
|
Outer core
|
The layer made up of liquid iron and nickel (molten metal) and surrounds the inner core
|
|
Lithosphere
|
A rigid layer made up of the uppermost part of the mantle and the crust
|
|
Pressure
|
The force pushing on a surface or area
|
|
Seismic Waves
|
A wave produced by and earthquake. Vibrations that travel through Earth carrying the energy released during an earthquake.
|
|
Where does Convection currents occur
|
heat in the mantle and outer core
|
|
What is Climate??? <3
|
Climate refers to the average weather conditions in a certain place over many years.
|
|
What do greenhouse gases do?
|
Gases in the atmosphere that trap energy
|
|
Greenhouse Effect
|
Process by which Earth's atmosphere traps solar energy
|
|
Global Warming
|
Gradual increase in the temperature of Earth's atmosphere
|
|
Mantle
|
The layer of hot solid material between Earth's crust and core
|
|
Outer core
|
A layer of molten iron and nickel that surrounds the inner core of the earth
|
|
Inner core
|
A dense sphere of solid iron and nickel at the center of the earth
|
|
Granite
|
A usuallylight colored igneous rock that is found in the continental crust
|
|
Greenhouse Gases
|
Gases in the atmosphere that trap solar energy
|
|
Name 3 greenhouse gases
|
carbon dioxide, wate vapor, methan
|
|
What is the outcome of burning wood, coal , oil and natural gas
|
Carbon dioxide is added to the air
|
|
How are humans contirbuting to global warming
|
by the burning of wood, coal, oil and natural gas
|
|
true or false. The amount of carbon dioxide in the air has been steadily increasing
|
True
|
|
T/F: Everyone agrees about the causes of global warming
|
False
|
|
How might changes in solar energy affect earth's climate?
|
The water will melt and the wate levels will rise and it will eventually submerge more land
|
|
indirect evidence
|
evidence you infer (such as rom seismic waves)
|
|
Temperature (to the center of the earth)
|
just beneath the surface the surrounding rock is cool. As you go further down it gets warmer,
|
|
Why is it difficult to determine the earth's inner structure?
|
because of the exteme conditions in the earth's interior.
|
|
how are siesmic waves used to prvide evidence about earths' interior?
|
they use data and found interior is made up of several layers
|
|
liquid - which layer
solid solid but able to flow |
liquid :outer core
soid: lower mantle, inner core, lithosphere solid but able to flow: asthensphere |
|
continental drift
|
the hypothese that the continents slowly move across the earth's surface
|
|
pangaea
|
the name of the single landmark that broke apart 200 million years agao and ge rise to today's continents
|
|
fossil
|
a trace of an anceint organism that has been preserved in rock.
|
|
conduction
|
Heat transfer within a material or between maters that are TOUCHING. (a spoon in a pot of soup heats up by conduction)
|
|
convection
|
heat transfer by the movement of curents within a fluid. The heated particles of fludid begin to flow. this flow transfers heat from one part of the fluid to another
|
|
density
|
a measure of how much mass there is in a volume of a substance.
|
|
convection current
|
the flow that transfers heat within a fluid. the heating & cooling of the fluids set the currents in motion.
