Matter Energy and Earth cycles Flashcards
Water cycle:
the cycle in which water evaporates from oceans and other bodies of water, rises into the atmosphere, falls as rain, then recollects into bodies of water where it starts the cycle over
Evaporation
“cleans” water in that it makes it leave most contaminants behind
Rock cycle:
the cycle in which rocks are formed and broken up and reformed
- Hot molten material inside the Earth, called magma, flows up through cracks in Earth’s crust.
- This new material loses heat and cools, forming new rock
- Over time, this new rock can be eroded into tiny bits
- The tiny bits can get compressed together to form a new rock
- Sometimes rocks are pulled under the ground deep enough where they are heated up and melted and begin the cycle over
List the 5 steps of the rock cycle
Atmosphere:
the relatively thin envelope of gases that forms Earth’s outermost layer
It is made of a mixture of gases, and other particles like dust
It contains Earth’s weather
What makes up the Atmosphere
Geosphere:
the solid metal inner core, liquid metal outer core, the rocky mantle and crust of the Earth
Hydrosphere:
all the Earth’s water, including water in the atmosphere
The cryosphere
is the frozen component of the hydrosphere, it is made of all the ice and snow on the planet
Biosphere:
the parts of Earth that contain living organisms
Energy
the ability to do work.
Heat from the sun
Heat from the Earth’s interior
Earth’s main sources of energy are which 2?
Heat from the sun
Heat from the Earth’s interior
These energy sources drive cycles of matter in the four spheres.
Feedback
a response to an event or action. the response may affect future occurrences of the event
positive feedback
will increase the occurrence or intensity of the event
