Flora & Fauna
A global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients. One of Earth's spheres.
Biosphere
Precious medium from which plants sprout
Soil
The surface configuration of Earth
Topography
Biological Weathering is caused by...
living things
Loosened by weathering on a dry, steep slope. One of the most dangerous.
Rockfall
Border area where species from both biomes intermingle
Ecotone
The loss of soil or soil nutrients to water or wind
Soil Erosion
An individual topographic feature (sand dune -> mountain range)
Landform
Rock openings
Collapse and movement of a slope; caused by several factors notably earthquakes
Landslide
The study of the distribution of living organisms and how these patterns change over time
Biogeography
It takes a _____ time for soil to form
long
The building blocks of rocks which are the building blocks of landscapes
Minerals
The most crucial force that causes mass wasting is...
gravity
Subsurface failure/movement of rock or regolith or permafrost
Slump
The number of different kinds of organisms present in a location
Biodiversity
One of the best signs of healthy soil; heavy weights in the world of soil cultivation and mixing
Earthworms
Rock formed when magma or lava cools
Igneous Rock
Chemical Weathering involves which threes things (who can name the most in the same chat)
Acid, Water, and Wind
Heavy rainfall, typically after a long dry spell. Creates a fan shape at the bottom.
Mudflow
Symbiosis
1. Mutualism - mutually beneficial
2. Parasitism - one benefited and one harmed
3. Commensalism - ...
One benefited; one neither benefited or harmed
Who can name the highest number of soil-forming properties (use a single chat message)?
Climate
Parent Material
Topography
Organisms
Time
Rock formed when heat or pressure act on existing igneous or sedimentary rocks
Metamorphic Rock
The steepest angle at which a material can rest without gravity acting upon it
Angle of Repose
Slowest and least perceptible type, caused by freeze/thaw cycle
Creep
