In what type of mine would a rock burst most likely happen?
an above-ground biomining site using mine waste
a large longwall mine
an open-pit mine with a large tailing pond
a strip mine near a water supply

A large longwall mine.

Explanation:

A rock burst is a dangerous hazard in which a violent fracture takes place in the rocks. A rock burst sounds like an explosion. It occurs spontaneously in deep mines and overburdened tunnels. The rock burst depends on the size of the excavation and the depth of the excavation or mining operation.

In longwall mining, a rock bust is more likely to happen because it is an underground method of coal excavation from tabular deposits.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
