Chemical Combat (Weathering)
What is the process of breaking down rock into other sediments ?
What is Weathering
If weathering is the hammer that breaks a rock into pieces, this process is the "getaway car" that carries those pieces away.
What is erosion?
What do you call a A hill of sand piled up by the wind, common in deserts and near beaches.
What is a Sand Dune
What are the three different rock types?
igenous, sedimentary, metamorphic
These are the three common, non-physical things that cause deposition, erosion, and weathering.
What type of chemical is harmful when rain mixes with carbon dioxide from factories, eating away at limestone statues.
What is Acid rain?
True or False: Erosion can only happen after weathering has already occurred.
What is true?
How does metamorphic rock transform in igneous rock A) Crystallizion B) Heat and pressure C) Weathering and Erosion
What is B) Heat and pressure?
As a river slows down at the ocean, it drops its sediment to form this triangle-shaped landform.
What is a delta?
True or False: Sand dunes are formed by deposition
What is True?
True or False: The Grand Canyon was formed in one single, massive earthquake.
What is False? (It was made by water from the Colorado river weathering the canyon into what is today)
I’m not a hammer, but I break things in two. I’m not a ghost, but I can slip right through. I wait for the temperature to drop below freezing, then I expand in the cracks—it’s quite rock-squeezing! Who am I?"
What is Ice/Frost Wedging?
I have no legs, but I travel for miles. I have no arms, but I can move a mountain into a pile. I’m the getaway driver for a rock that’s been smashed; I leave the scene of the crime before I get crashed. Who am I?"
What is Erosion?
"I’m the end of the road, the final stop. I’m where the heavy baggage finally gets dropped. When the wind stops blowing and the water slows down, I build up the layers of a brand-new town. Who am I?"
What is deposition?
I’m the rock’s 'reboot' button, glowing and red,
I’ll melt every crystal until it is dead.
Inside I am Magma, outside I am Lava,
I’m hotter than steam in a cup of hot java! Who am I?"
What is molten rock?
