Rock Cycle and Formation
What are the three rock types?
Igneous, Metamorphic, Sedimentary
Who came up with the continental drift theory?
Alfred Wegener
What is the theory of tectonic plates?
Earth's crust is divided into large plates called tectonic plates that move.
What is the best subject?
Science
Which rock type does this description match. Rocks are pushed together by pressure and heat overtime to form a new rock.
Metamorphic Rock
State what the theory of continental drift is.
Continental drift explains the continents were once a supercontinent which have moved away/drifted apart over time.
Explain how the tectonic plates move.
Convection currents from magma beneath Earth's crust.
What are my 2 teachers names?
Mr Dunn and Miss M
Explain how sedimentary rocks are formed?
When sediments are deposited on top of each other forming layers that compact over time to form rock.
What was the supercontinent called?
Pangaea
What is tectonic plate activity responsible for?
Ballet originated in what country?
Paris
What are the two types of igneous rock and name one property of each type?
Extrusive: cool quickly, brittle, lightweight
Intrusive: cool slowly, have crystals, strong
Rock formations and fossils found on continents showed how they linked like puzzle pieces.
What are the three plate boundaries called?
Transform, Divergent and Convergent boundaries
What is the chemical symbol for GOLD?
AU
State the processes that need to occur for each rock type to change into another type.
Igneous/Metamorphic to sedimentary = Uplift and erosion/weathering.
Metamorphic/Sedimentary to Igneous = Melting
Sedimentary/Igneous to Metamorphic = Heat and Pressure
Explain why Alfred's theory was not supported by many scientists back then.
Little to no evidence to support his theory as they did not have the technology.
Explain in detail the movement of each plate boundary and describe the geological activity linked to that type of plate boundary.
Divergent - move away (magma rises creating new crust/ridges)
Convergent - move towards (1 plate slips under another causing mountains and or volcanoes)
Transform - slide past each other (causes Earthquakes)
Who won the 2025 NRL?
