From small beginnings, South America grew to greatness because of maize. Just did this and it's correct.
The type of chemical sedimentary rock that would fizzle if exposed to acid (recall that the mineral calcite reacts vigorously to hydrochloric acid) is Chalk.
Sedimentary rocks are shaped from deposits of pre-present rocks or pieces of once-living organisms that gather on the world's floor. If sediment is buried deeply, it turns into compacted and cemented, forming sedimentary rock.
Common sedimentary rocks consist of sandstone, limestone, and shale. these rocks frequently begin as sediments carried in rivers and deposited in lakes and oceans. when buried, the sediments lose water and turn out to be cemented to form rock. Tuffaceous sandstones incorporate volcanic ash.
Sedimentary rocks are varieties of rock that might be shaped by means of the buildup or deposition of mineral or natural debris at Earth's surface, accompanied by cementation. Sedimentation is the collective call for methods that reason this debris to settle in the area.

<span>When forests are stripped off of plant life the results in the environment would be catastrophic. Landslides, excessive soil erosion, depletion of habitat, increase in greenhouse gases, and excessive pollution will be the results of deforestation. The ecological balance will go into chaos if this continues and a lot of organisms will suffer in the long run. This is a direct cause of human activity that is powered by greed and constant wanting for things that are hard to achieve.<span>
