What are two ways to mine coal?
Coal is mined by two methods: surface or 'opencast' mining or underground or 'deep' mining.The choice of mining method largely depends on the geology of the coal deposit. Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coal producing countries surface mining is more common.
What two names for the process by which soil and rock are stripped from the Earths surface to expose underlying coal?
The two names for this process are surface mining or strip mining. Surface mining involves removing layers of soil and rock to access coal deposits beneath the surface. Strip mining specifically refers to the method of removing layers in strips to expose coal seams.
Two ways to reduce the effects of mining?
Eating and cleaning minerals with h2o2
What are the two methods used for mining coal?
The two methods used for mining coal are surface mining and underground mining. Surface mining involves removing layers of soil and rock to access coal deposits near the surface, while underground mining involves tunneling underground to extract coal from deeper deposits.
What are two ways in witch the value of soil can be reduced?
Soil value can be reduced by erosion, which removes topsoil and degrades soil quality, as well as contamination from pollutants, chemicals, or heavy metals which can render the soil unsuitable for cultivation.

What are two positive effects from mining cattle and farming?
Cattle ranching can have many benefits. The cattle can be used as a meat product and their excrement provides nutrients back to the soil.
What are two of the ways coal is mined?
Coal is typically mined using two methods: surface mining and underground mining. Surface mining, which includes strip mining and mountaintop removal, involves removing the topsoil and rock layers to reach the coal seam. Underground mining involves digging shafts and tunnels to access coal seams deep underground.
What are two ways mineral mining can affect land?
When you mine, you can be destroying homes of animals, and disrupting natural habitats.
What are two ways to reduce the environmental effects of mining?
Implementing strict regulations and monitoring to mitigate pollution and habitat destruction during the mining process. Promoting recycling and reuse of materials to reduce the demand for new mining operations.
What ways are two ways that water cycle and water on earth and the water cycle are related to weathering and erosion?
Water cycle removes top soil. It decreases the fertility of soil.
