Hot Water!
This is one of the most famous geysers in the world!
What is 'Old Faithful'?
This is gravity pulling soil and rocks down a hill.
What is a landslide?
This is the most important component (part) of soil for growing plants.
What is humus? (pronounced hyoo-muhs)
Not hummus! (which is delicious!) (but not if it's in the dirt!)
The process of wearing down rocks is called ______________.
What is 'weathering'?
A formation in a cave that goes from floor to ceiling (or ceiling to floor) is called a _______________.
What is a column?
A thermal feature that shoots hot water many feet into the air is a ___________________.
What is a GEYSER?
RAPID movement of LARGE AMOUNTS of rocks and soil is called ________ _______________.
What is 'mass wasting'?
This is the most powerful eroding force
What is moving water?
Which is more easily eroded, iron or rust?
Rust is more easily eroded!
Caves are formed mainly from this type of rock.
What is limestone?
This 'thermal feature' (hot water in the earth) is when a bunch of hot steam escapes from the ground. Just steam. No water, no mud. Just steam.
What is a fumarole?
(it's the only thermal feature that is just steam!)
This is the force that causes water to move rapidly down a hill.
What is gravity?
Including sand, silt, and organic material, what are the other two main ingredients of soil?
What are water and oxygen?
What is a more powerful eroding force - fast moving or slow moving water?
Fast moving water is a more powerful eroding force.
After a volcanic eruption, this substance that comes from it can become fertile soil.
What is ash?
This type of energy can be obtained from areas containing geysers.
What is Geothermal? (Geo=earth, thermal=hot ... makes sense, since the earth sure is hot near geysers!)
This is where rock glaciers are likely to be located.
Where is in mountain areas with steep slopes?
This is the measure of air spaces in soil.
What is porosity?
This weird event is the process that brings rocks to the surface each winter.
What is frost heaving?
It IS weird! Rocks show up above ground!
This is why porosity and permeability are important to growing things.
• Too much porosity/not enough permeability - nothing grows.
• Medium porosity and permeability - things grow well!
Geysers often contain this substance, which gives them a bad smell.
What is Hydrogen sulfide? (EWWW! rotten eggs!)
Describe a fossil rock glacier.
A fossil rock glacier is a rock glacier with no more ice in it, that doesn't move. (No ice, no movement)
This is the measure of how quickly water moves through soil.
What is permeability?
These are two types of Chemical Erosion.
What is Acid and Water (And Oxygen)?
any two of those three.
These are two evidences of a large scale flood we find in the Grand Canyon.
These are three:
• flat lower layers of strata
• marine fossils everywhere
• Bent, not broken layers
