mining
one way we can reduce the necessary amount of mining is...
what is recycling?
one way to improve soil health and reduce erosion is to
what is planting cover crops?
soil is is formed from the weathering of
what is parent rock?
sustainable means..
what is a resource that is replaced at the rate it is consumed
what is an example of wasting a nonrenewable resource.
using to much oil then we need to, not being mindful of the amount of things we use, overusing minerals that are being mined.
three ways minerals are used in everyday life
what are in food, buildings, cosmetics, etc.
organic foods have less...
what is pesticide residue?
name the three main types of soil particles
what are sand, silt, and clay?
how can we prevent from running out of nonrenewable resources
not waste/overuse resources that we use daily
how can erosion effect farming.
it can move soil, water, and nutrients from where they need to be
subsurface mining is better than surface mining in these ways...
but is worse in these ways...
what is subsurface mining causes less surface damage/environmental harm, but is less safe and can cause acid mine drainage?
one way vertical farms are more sustainable is...
what is require less land, produce higher yield, recycle water, use fewer fossil fuel, or don't require pesticides
the six soil horizons are..
what are the O, A, E, B, C, and R horizons?
name three renewable and nonrenewable energy sources
renewable: sunlight, water, tidal, geothermal, etc
nonrenewable: natural gas, coal, nuclear, etc.
what could be the solution of drought in an area
cover crops, crops rotation.
4 properties of minerals/crystals are...
what are color, hardness, luster, streak, etc.
plants can become more disease-resistant and increase in yield through...
cross-breeding/selective breeding
how are the 4 spheres all components of soil?
biosphere: plants/plant roots, bacteria
geosphere: minerals
atmosphere: air pockets
hydrosphere: water
nuclear energy is nonrenewable because..
uranium must be mined/will run out
what are some impacts of agriculture on the environment
destruction of habitat, soil erosion, fertilizer and pesticide runoff, overuse of water resources.
ore mined from underground is called..
what is land won ore?
four sustainable farming practices are..
what are cover crops, strip cropping, crops rotation, and rotate livestock grazing
name the properties of the eluviation layer
dry, barren layer because water has leached the nutrients & minerals into lower layers
what is biomass and how is it used as a renewable energy source
biological waste/matter that can be burned for heat/energy or converted to liquid/gaseous fuels
who succeeded in cross-breeding plants to prevent us from starving and to where we could actually eat what we grew.
