What is a Merritt Hypsometer?
This is the crust and uppermost area of the mantle.
What is the Lithospere?
The physical environment in which individuals of a particular species live.
What is habitat?
All the organisms in a given ecosystem and the abiotic environmental components that interact.
What is an ecosystem?
All the organic material- (biotic) that makes up an ecosytem.
What is biomass?
The stem of a deciduous tree contains one bud at the tip that is responsible for the growth of the tree
What is the terminal bud?
These two tools can be used to determine percent life cover.
What is a quadrat and a densitometer?
This type of boundary does not create or destroy land at it's margin.
What is a transform boundary?
The movement of life's essential chemicals or nutrients through an ecosystem.
What are biogeochemical or nutrient cycles?
Is defined as area of wood in a given tree or on a parcel of land collectively.
What is basal area?
Tundra, tropical rainforest, scrub and savanna are all biomes. What two things make them distinct?
What are temperature and percipitation?
These two items (typically a section of light and dark wood) collectively make up one years growth or one ring on the tree.
What is the early and late wood?
This booklet contains information on board foot volumes using Doyle, Scribner and International 1/4. What are those names called?
What are Log Rules?
These two types of land forms occur when two oceanic plate boundaries collide.
What are island arcs and trenches?
Validity refers to accuracy while this item in the investigation refers to precision, or getting the same result again and again.
What is reliability?
International, Doyle, and Scribner are called
What are log rules?
Resources so critical that their availability controls the distribution of species.
What are limiting factors?
The part of the tree that is responsible for cell division
What is the cambium?
A marked location on the gps unit (latitude and longitude) is called?
What is a waypoint?
A convergent boundary zone creates these type of landforms.
What are mountains and ocean trenches.
The role a species plays in its community including how it obtains energy, habitat, and behavior in its ecosytem.
What is niche?
Molecules moving from and area of high concentration to an area of low concentration
What is diffusion?
A process where atmospheric nitrogen (N2) is converted by bacteria into ammonia (NH3); which is a usable form of nitrogen for plants.
What is nitrogen fixation?
These cells transfer water and minerals from the roots to the upper parts of the tree
What is the xylem?
The windows on the angle gauge represent numbers that are called?
What are Basal Area Factors?
The part of earth that is responsible for creating earth's magnetic shield.
What is the outer core?
The two processes that make continental drift possible
What is convection and gravity?
This biogeochemical cycle does not move through the atmosphere, but cycles between organic to inorganic form through a series of interactions with water and organisms.
What is the phosphorous cycle?
Open-pit mining and animal waste contribute to which cycle?
What is the phosporus cycle?
These types of cells transport terpenes to the heartwood of a tree for protection from insects and disease
What are medullary rays?
These three tools can be used to determine basal area on a forest cruise.
What is the angle gauge, prism, and cruiser's crutch?
A property of the aesthenoshere, which means it can behave like a plastic or an elastic.
What is a viscoelastic?
In the range of tolerance for any given species, when an environmental factor like temperature increases/decreases species begin to decline. What is this zone called?
What is the Zone of Physiological Stress?
The process of leaves dying and the petiole breaking from the stem during fall.
What is abcission?
Microbes use NO3 and convert it to N2, completing the cycle
What is denitrification?
