Geological features
What type of rock forms from the deposition of sediments in basins?
What is sedimentary rock?
What distinguishes igneous rocks from metamorphic rocks?
What is the presence of crystals in igneous rocks and foliation in some metamorphic rocks?
What happens when oceanic and continental plates converge?
What is one plate subducts under the other, potentially forming volcanoes?
Which is older oceanic crust or continental crust?
What is Continental crust?
What process leads to the formation of igneous rocks?
What is melting and cooling of molten rock?
What are the possible interactions between continental crust and oceanic crust?
What is converged where the oceanic plate subducts below the continental plate?
And
What is a transform fault where the plates slide past each other?
And
What is divergent boundary where the plates separate from one another forming a trench?
What process leads to the formation of metamorphic rock?
What is heat and pressure?
What is a transform fault?
What is where plates slide past each other?
Why is oceanic crust younger than the continental crust?
What is because it is constantly recycled through subduction?
What happens to rocks when they are weathered?
What is they break down into smaller particles (sediments)?
What is the purpose of relative dating when determining the age of rocks?
What is to determine the age relationship between different rock types?
Name a characteristic feature of metamorphic rocks.
What is foliation?
How do converging continental plates impact Earth’s landscape?
What is they can create mountains?
What is the estimated age of the Earth?
What is 4.6 billion years?
A rock is under pressure and heat to the point where it fully melts. What kind of rock does it become?
What is an igneous rock?
What is an igneous dike?
What is a type of intrusive rock formed when magma intrudes into existing rock?
I Will also take: What is a rock that is intrusive in layers making it younger than the rock around it?
How do igneous and metamorphic rocks differ in their formation processes?
What is igneous rocks form from cooling molten rock, while metamorphic rocks form from existing rock altered by heat and pressure?
Why might simplified models of plate tectonics not fully represent reality?
What is they do not capture the complexity of actual plate boundaries?
Why does continental crust tend to be much older than oceanic crust?
What is its lower density prevents it from subducting?
How does an igneous rock become an igneous rock?
What is the rock melts?
How do sedimentary rocks like sandstone end up in high elevations?
What are sedimentary rocks from in a basin and when tectonic plates move they cause an uplift of continental crust causing the sedimentary rocks to end up in high elevations?
What is the difference between the layers found in sedimentary rocks and foliation?
Foliation is formed by intense heat and pressure. Sedimentary rocks form from layers of sediments building up horizontally in a basin over time.
In a location where oceanic plates are subducting, where are volcanoes likely to occur?
What is on the continent?
Scientists recently discovered a patch of oceanic crust deep beneath the Mediterranean Sea that is estimated to be 340 million years old. It is the oldest oceanic crust ever found.
If scientists believe Earth is actually 4.6 billion years old, why haven’t scientists found older oceanic crust?
❍ A Rocks did not cool on Earth until about 340 million years ago.
❍ B It is too hard to collect samples of oceanic crust.
❍ C Oceanic crust subducts under continental crust as new oceanic crust forms.
❍ D Oceanic crust is younger than continental crust
What is answer C?
For a sedimentary rock to change into another kind of sedimentary rock, it would first need to _____.
What is weathering?
