What process breaks rocks into smaller pieces?
Weathering
What process forms clouds?
Condensation
What effect causes wind and water to curve on Earth?
Coriolis Effect
What are the three types of plate boundaries?
Convergent, divergent, transform
Which layer is liquid and where the convection currents occurr?
What two processes help form sedimentary rock?
Compaction and cementation
What is precipitation?
Water falling from clouds as rain, snow, sleet, or hail
Why does warm air rise?
It is less dense
Which type of plate is denser: oceanic or continental?
Oceanic
What type of boundary causes earthquakes?
stress leased from a TRANSFORM BOUNDARY
What type of rock forms from heat and pressure?
Metamorphic rock
How does the Sun drive the water cycle?
The Sun provides heat energy for evaporation
What do are the names of the 3 cells that help spread heat around the globe?
Hadley, Ferrell, and polar
What evidence supports continental drift?
Pangea/puzzle pieces
Same fossils on different continents
Matching rocks and mountains
which type of boundary does a process to form mountains?
convergent boundary through uplift
One rock type can change into another in the rock cycle through:
Through melting, cooling, heat/pressure, weathering, erosion, compaction
Transpiration
What direction do winds curve in the Northern Hemisphere?
The right - clockwise
What inside the earth is responsible for the movement of the plates?
The convection currents in the mantle
Explain how did density affect the creation of Earth’s layers during accretion.
Dense material sank; less dense material rose
