What is the dwarf, Gimli's, father's name in Lord of the Rings?
What is Gloin?
This is any process that breaks rocks into smaller pieces without changing what the substance of the rock originally is.
Mechanical Weathering
This process changes the materials in a rock.
Chemical weathering
This is the unweathered, solid parent rock beneath the soil profile.
R - Horizon.
This dynamic natural mixture of minerals, humus, water and air capable of giving plants LIFE?
Soil
What race did Aragorn belong to in Lord of the Rings?
What is the Dunedain?
True or False: The intense temperature of a forest fire causing nearby rocks to expand and crack is an example of mechanical weathering.
True
Rain can be an agent of chemical weathering because of this fact.
Rain is acidic.
In this horizon, you will find the most organic material of all the horizons (earthworms, bacteria, root networks).
A - Horizon
What is humus?
Dark, organic material that came from the decomposition of plant and animal matter.
What are the six Infinity Stones in the MCU?
What are the Space Stone (blue), Reality Stone (red), Power Stone (purple), Mind Stone (yellow), Time Stone (green), and Soul Stone (orange)?
This type of mechanical weathering is the grinding away of rock by friction or impact. An example would be a strong current in a stream carrying losse fragments of rock downstream and breaking them into smaller pieces.
Abrasion (wind & water)
This is the name of the process when the element of oxygen is combined with another element or molecule. It is a type of chemical weathering.
Oxidation
This is the subsoil layer, usually lighter in color dense in fine clay particles.
B - Horizon
What are the 4 (four) core ingredients that are required to make soil?
1. Weathered rock fragments (minerals).
2. Organic matter (humus).
3. Water.
4. Air (provides oxygen for root respiration)
What is the Latin motto of the Gryffindor house in Harry Potter?
Forti Animo Estote, meaning "Be of Good Courage", or "Stay Strong of Heart".
This type of mechanical weathering is when waters enters a crack in a rock and freezes, expanding and breaking the rock into smaller pieces.
Ice (frost) wedging
While walking down your street, you notice a house that has its address carved into a rock on their front porch. The numbers are starting to become faded and are hard to read. How has chemical weathering contributed to this?
Rain, being slightly acidic, has most likely weathered the rock.
This is the altered parent rock layer, with little to no organic material.
What is leaching?
The downward removal of dissolved minerals and nutrients from upper soil horizons by downward water.
What does S.H.I.E.L.D. stand for?
What is Strategic Homeland Intervention, Enforcement and Logistics Division?
This is an example of how plants or animals can cause weathering.
Plant roots an grow through cracks and rock, breaking the rock into smaller pieces. Animals create holes in the ground that allow water to enter and cause weathering. Animals that burrow also break down rocks as they dig.
Why do sink holes eventually collapse?
What is carbonic acid disssolving the parent bedrock (limestone and marble)?
How is transported soil different from residual soil?
Transported soil was weathered elsewhere are carried by ice glaciers. Minerals is transported soil do not match the underlying bedrock.
What does the acronym C.O.R.P.T stand for, regarding soil development?
C - Climate (determines rate of leaching)
O - Organisms (determines amount of humus)
R - Relief/Slope (steep = thin soil = erosion)
P - Parent (chemical nature dictates minerals)
T - Time (soil increases over years)
