Answer:
<u>Yes , They are architectural structures that shape the geology of earth.</u>
Explanation:
- These geologic structures influence the shape and size of landscape development and determine the degrees to landscape hazards. Folds and faults and other geologic structures accommodate large forces/stress on earth's tectonic plates.
- Foldes are of two types such as Syncline and Anticline. Formed due to the crustal bending and wrapping of the geo sediments or rocks. The youngest at the top and the oldest at the bottom. As antiforms contain comparatively younger folded rock strata.
- Faults are a planar surface within the earth, where the rocks have slid or broken a fault may be caused due to the elastic strains on the rocks, the rocks on either side are shifted in opposite direction and the faults get induced.
- There are many types of faults and folds in the history of the earth's surface, many of these have led to the formation or shaping of mountain ranges and various mountain chains.
- Another example can be of Mount Everest which is a young folded mountain formed from the colloid of the Tethys sea when India was once a part of the Australian continent.
- Plate tectonics is thus directly related to the formation and motion of the plates which mover the entire planet and shape its orogeny
The Louisiana Purchase of 1803 to become part of U.S. territory doubled the size of the country
