What environmental problems are caused by open-pit mining?
Some environmental problems that are caused by open-pit mining are that it greatly alters the environment through wind and water erosion, loss of habitat, destruction of plant life, and water and soil contamination.
how does magma become igneous? melting, cooling, weathering, or heat and pressure.
cooling
how does recycling change the life of an aluminum can
Look up how raw aluminum is extracted and processed
Explain it
Explain recycling aluminum
Compare and contrast the two processes
Recycling is a shortcut-much less energy to recycle than to make more
Recycling aluminum saves 90%-97% energy
Any natural substance, organism, or energy source that living things use

definite chemical composition: Chemical composition is the same throughout the mineral.
What are three items that you throw away which are biodegradable

Name an advantage and a disadvantage of using core sampling to locate minerals
Advantage: It helps to see what’s underneath the ground, and you can core sample a large area
Disadvantage: You can’t core sample everywhere: you might miss a vein, or it could give you an inaccurate pictures there is also no money made from core sampling
how does igneous and metamorphic become sedimentary? melting, cooling, weathering, or heat and pressure.
weathering
Name two special properties of some minerals.
fluorescence and magnetism
Repurposing is one of the four “R’s” to reduce the amount of garbage that ends up in landfills. Explain repurposing
Repurposing is taking something that can’t be used again for its original purpose and using it for something different. For example, using a ripped plastic bag to make art

renewable: trees, cotton, water, and food
Non-renewable: oil, coal, minerals, and gas
