constructive processes that build mountains

Interpret or summarize the ideas in own words. Thinking Skills: Understanding: Understand the main idea of material heard, viewed, or read. 3.2.b - Explain factors that change Earth’s surface.

3.2.a - Identify how forces change Earth’s surface. “Destructive” forces are those like erosion or weathering in which landforms are broken down into smaller pieces like soil and sand. State Standards: Colorado Academic Standards for Science. That is, volcanoes often result in the construction of new landforms. To scientists, volcanoes are known as “constructive” forces. Is a volcano constructive or destructive? of sediment at the mouth of the Mississippi River creating new land called a delta. Is a delta constructive or destructive?ĭeposition: the placing of materials in a new place ( constructive force).

Mountains are also an example of a slow constructive force due to two tectonic plates being pushed into each other. Water carries sediment down river and as the river becomes more shallow, the sediment is deposited, forming landforms such as deltas. Is a mountain constructive or destructive? The two mechanisms at work to construct the Colorado Plateau and the Grand Canyon are uplift (constructive), and erosion (destructive). The ultimate limiting force to mountain growth is gravity. Is the Grand Canyon a constructive force? What are 4 constructive forces?Ĭollection and analysis of data indicates that constructive forces include crustal deformation, faulting, volcanic eruption and deposition of sediment, while destructive forces include weathering and erosion. RECOGNITION OF THE MANY TYPES of feedback in the mountain-building system reveals that erosion not only participates in shaping mountains but also guides tectonic processes deep within the crust. A constructive force is a process that raises or builds up the surface features of the Earth.
