The grassland of North America is a "steppe climate" in fact in Russia grasslands are called Steppes. This climate makes us prone to WEATHER from high pressures and low pressures meeting up and not liking each other very much - Lightning, Hail, Tornados, Floods, and in the northern parts Blizzards. Basically Winds and Clouds are what we watch and monitor - beautiful, dangerous, and can go from benign to ferocious in the blink of an eye. Weather can kill and weather can be a salvation. It depends on the whims of pressure.
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. ... This changing of rock types is called the "Rock Cycle".
