Answer:
The Colorado River carves land in Arizona to form the Grand
Canyon. - Erosion
Cracks form in a sandstone wall surrounding a house. - Erosion
A marble statue near the science museum is changing color due to
rainfall. - weathering
After a rainstorm, soil and rock pieces litter the roadways. - weathering
The sand dunes in the Sahara Desert are changing shape. - erosion
Explanation:
Definition of Erosion: the process of eroding or being eroded by wind, water, or other natural agents
Definition of weathering: the process of wearing or being worn by long exposure to the atmosphere
The grand canyon was formed by a River therefore water.
Cracks in a sandstone wall would be caused by natural agents.
A marble statue changing color due to rainfall is exposure to the atmosphere (rain).
After a rainstorm, soil and rock pieces litter the roadways, it basically tells you the answer.
A sandstorm is described as a natural phenomenon that occurs when a strong wind, such as a gust front, blows fine sand particles and dust from a dry surface. These particles become suspended in the air, causing erosion where they initially were. The wind drops these particles in another place where silt is formed. So, wind blowing sand is erosion.
Hope this is correct!
