Valleys and mountain ranges are formed through the process of tectonic plate movements. When tectonic plates collide, they can buckle and fold, leading to the formation of mountain ranges. The pressure during this collision can cause rocks to deform, and over millions of years, this deformation leads to the creation of peaks and ridges. On the other hand, valleys are often formed through erosional processes like rivers, glaciers, or weathering, where the land is gradually worn down and shaped into lower-lying areas between peaks or ridges in mountain ranges.
a student claims that earthquakes are more destructive than tsunamis, in one or two sentences, explain at least two reasons that support the students claim
One reason earthquakes can be more destructive than tsunamis is that they can directly impact a larger area, causing widespread damage and destruction. Additionally, earthquakes can result in secondary hazards such as landslides and fires, further exacerbating the destruction.
Describe how the Yukon River Delta in Alaska could be changed over time
The Yukon River Delta in Alaska could be changed over time due to various natural processes and human activities. Natural erosion and sedimentation can alter the shape and size of the delta. Changes in river flow, caused by factors like climate change or upstream human interventions, can impact the deposition and distribution of sediment in the delta. Rising sea levels can contribute to the coastal erosion of the delta. Additionally, human activities like land development, dredging, or the construction of dams can also modify the delta's characteristics, potentially affecting its landforms, vegetation, and wildlife habitats.
