100
This process breaks apart rocks through physical forces without changing what the rock is made of.
What is mechanical/physical weathering?
100
This event occurs the moment sediment carried by water, ice, or wind finally slows down or stops moving entirely
What is deposition? (Accept: the sediment is deposited )
100
When rainwater gets trapped in a rock crack and the temperature drops below 0ºC (32ºF) this substance forms and expands, breaking the rock.
What is ice? (This refers to ice wedging/frost wedging).
100
This weather event must happen first so that liquid water can fill the crack in the rock before any freezing can take place.
What is rain?
100
These giant, moving puzzle pieces make up Earth's outer crust and constantly glide, crash, and slide past one another
What are tectonic plates?
200
These two everyday weather elements can work together to slowly break down exposed rock on Earth's surface
What are wind and rain?
200
In a river, erosion happens where fast-moving water picks up soil, while deposition happens here, where the water slows down.
What is when it enters a larger body of water? (Accept: at the mouth of the river).
200
This specific type of rock is famous for being dissolved by acidic groundwater to create massive underground caves.
What is limestone?
200
For frost wedging to successfully split this rock, the temperature must drop to or below this specific measurement shown in the diagram
What is freezing point?
200
This explosive geologic feature changes Earth's surface rapidly by blasting out molten lava, ash, and gases from deep underground.
What are volcanoes?
300
This type of weathering happens when chemical reactions dissolve or change the actual minerals inside a rock.
What is chemical weathering?
300
This fan-shaped landform is created at the mouth of a river due to the deposition of sediment.
What is a delta?
300
Looking at the satellite image of Algeria, these rock layers had to be compacted and formed before a meteorite could crash into them.
What are sedimentary rocks?
300
This circular, low-lying geologic feature in Algeria was created when a massive space rock crashed into Earth's surface.
What is the Quarkziz impact crater?
300
When tectonic plates violently slide past or bump into each other, they release stored-up energy that causes this shaking hazard on the surface.
What is an earthquake?
400
Chemical weathering happens the absolute fastest under conditions that feature high temperatures and this specific liquid resource.
What is abundant water? (Accept: lots of water/rain).
400
This is the term for water that flows over Earth's surface rather than soaking into the ground, and its amount is determined by rain, slope, and vegetation
What is runoff?
400
This geologic feature was carved directly out of the Quarkziz impact crater by the power of water erosion.
What is a stream channel?
400
According to the labels, this specific liquid acts as a chemical weathering agent by dripping through cracks and dissolving the rock layers below.
What is water?
400
These massive crustal features are slowly built over millions of years when two continental plates smash together and crumple upward.
What are mountains? (Accept: mountain ranges).
500
Water acts as a weathering agent when it grinds moving particles against a rock, or when it does this to a rock's internal minerals
What is dissolving them?
500
To form sedimentary rock, layers of sediment must first experience this process of being squeezed together tightly over time.
What is compaction? (Accept: compacting).
500
This is the order of events that shaped the Algerian desert landscape: first came sedimentary rock formation, second came a meteorite impact, and third came this process.
What is water erosion? (Accept: a stream channel forming ).
500
These sharp, tiny lines spreading out into the grey area show exactly what happens to the solid rock after the ice expands
What is the rock cracking or breaking apart? (Accept: mechanical weathering)
500
Unlike slow weathering and erosion, earthquakes and volcanic eruptions change Earth's surface in this specific frame of time.
What is rapidly? (Accept: suddenly, instantly, or quickly).
