Biomes
Open regions that are dominated by grass and have a warm, dry climate.
What is Grassland?
The continuous journey water takes as it circulates between the oceans, atmosphere, and land.
What is the water cycle?
Consists of a network of tubes that have small holes. They can be placed above or below the soil's surface and slowly drip water into the soil over long periods.
What is drip irrigation?
The use of herbicides, insecticides, and fungicides to manage pests.
What is chemical control?
Any single, identifiable source, like a pipe or ditch, from which pollutants are discharged into the environment.
What is point source pollution?
Dry areas where rainfall is less than 2 inches per year. They can be either cold or hot with extreme conditions.
What is Desert?
The continuous exchange of carbon between living things and the environment.
What is the carbon cycle?
Water flows through a series of pipes and is delivered in a fine spray to specific areas. Mostly effective for tree crops and use less water, and are cheaper to run.
What is sprinkler irrigation?
the use of living organisms, such as predators, to manage pest populations.
What is biological control?
what is hydraulic fracturing?
They have extremely inhospitable conditions, with low amounts of precipitation. Not much biodiversity and vegetation is simple.
What is Tundra?
The process where nitrogen circulates between the atmosphere, soil, water, and living organisms.
what is the nitrogen cycle?
Is self propelled and works with the use of the central pipe with outlets rotating around the central point. Works like the sprinkler irrigation, but is much larger.
What is centre pivot irrigation?
Relies on long term prevention, careful monitoring, and biological or physical controls.
What is IPM?
The measure of the cloudiness of a fluid caused by particles like clay, silt, algae, and organic matter.
What is turbidity?
A subarctic climate with long, cold winters, and short, moist summers. It is dominated by cold tolerant evergreen coniferous trees.
What is Taiga?
The movement of phosphorus through the lithosphere, hydrosphere, and biosphere. The only major cycle without an atmospheric component.
What is the phosphorus cycle?
A form of surface irrigation where small parallel channels are created and filled with water. Crops are grown on the ridges between the channels.
What is furrow irrigation?
Practice of planting different types of crops in the same area across a sequence of growing seasons. Farmers alternate plant families to improve soil health, manage nutrients, and prevent pests.
What is crop rotation?
widespread, diffuse contamination that does not originate from a single, identifiable source like a discharge pipe.
What is non point source pollution?
They are constantly warm and have intense precipitation.
What is Tropical Rainforest?
The process through which the three main rock types transform from one type into another.
What is the rock cycle?
An old agriculture practice that still exists today, generally in mountain regions. A series of steps are cut into the sloped land so that when it rains, the water flows down from the top.
What is terraced irrigation?
A chemical substance or biological one used specifically to destroy or control unwanted plants, aka weeds.
What is a herbicide?
A harmful type of air pollution characterized by a visible, often brownish haze in the atmosphere.
What is smog?
