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?
What are some of the 'agents' of deposition? Name at least three
What are Gravity, Water, Wind, or Ice.
How does metamorphic rock transform in igneous rock A) Crystallizion B) Heat and pressure C) Weathering and Erosion
What is B) Heat and pressure?
In the order that the WED cycle happens: First you Break it, then you Take it, then you...
What is Drop it or Deposition?
These fuzzy, crusty things that grow on rocks actually "eat" the stone by spitting out a tiny bit of acid to break it down.
Hint: They start with the letter L
And they were mentioned in the word wall.
What are Lichens?
While wind and ice are strong, this is the most powerful agent of erosion on Earth, responsible for carving out everything from tiny gullies to the Grand Canyon.
What is Moving Water or Rivers?
As a river slows down at the ocean, it drops its sediment to form this triangle-shaped landform.
What is a delta?
This is the scientific name for the tiny "crumbs" of rock (like sand, silt, and clay) created during the weathering process.
What is Sediment?
True or False: Sand dunes are formed by deposition
What is True?
These living things can actually "eat" rocks by shoving their roots into cracks until the stone snaps in half.
What are Plants or Tree Roots?
When gravity gets impatient and pulls a whole hillside down at once after a big rain, it’s called this.
What is a Landslide or Mudslide?
So if, weathering breaks the mountain and erosion takes the mountain what process is the only one that makes something new?
What is Deposition?
This is the process where sediments are pushed together tight
What is Compaction?
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?
what is the point of the weathering erosion and deposition cycle
The weathering, erosion, and deposition cycle is Earth’s way of constantly remodeling its own surface. It is not an intentional "plan," but rather a continuous, interconnected system driven by gravity and climate that recycles the planet's solid materials.
