Answer:
Open-cast mining
Explanation:
The aftermath of open cast mining are pits (called quarries) on the surface of the earth where the surface soil has been removed/ displaced to access the mineral deposits that are just close or at the surface of the earth. This type of mining results in environmental degradation because they disturb the biodiversity of the ecosystem in which the mining is taking place. Rehabilitation of the area is required after the mining has been exhausted to restore the initial environment.
Clouds and Strom
The troposphere is the most minimal layer of Earth's environment that is closest to humans , and is likewise where almost all climate conditions happen. It contains roughly 75% of the climate's mass and 99% of the aggregate mass of water vapor and pressurized weather elements occur
The type of stream valley likely to form in a mountainous area is a V- shaped valley. This is a narrow valley that has a profile giving the impression of the letter V. This kind of valley is characterized by steeply sloping sides. It results from a stream eroding downward, a process referred to as downcutting. V - shaped valleys form in mountains or highland areas where streams are in their youthful stage and are flowing rapidly down steep slopes.

Answer:
Substitution Mutations
Explanation: A substitution mutation occurs when specific bases (A, T, C or G) in a gene are swapped for different ones. This type of mutation doesn't cause a difference in the number of bases like insertion or deletion mutations do. Substitution mutations just switch out one or more bases for different ones.
