How can moving water contribute to physical weathering?
A It can transport rocks to different locations
B It can cause rocks rocks bump against each other
C It can cause the formation of new minerals in rocks
D It can make rocks expand and contract
B It can cause rocks rocks bump against each other
The correct answer is B. Moving water can cause rocks to bump against each other, leading to physical weathering. As the water flows, it carries along loose sediment particles, and these particles can act as abrasives that impact and collide with other rocks. Over time, this repeated collision and abrasion can result in the breakage and fragmentation of rocks.
The correct answer is B - It can cause rocks to bump against each other.
When moving water flows through an area, it can pick up loose rocks and sediments. As the water carries these materials downstream, the rocks can collide with other rocks or the riverbed, causing them to break apart through a process known as abrasion. The constant impact and friction between rocks as they are transported by the water can weaken their structure and lead to physical weathering.
This process of rocks bumping against each other in moving water is commonly observed in rivers, streams, and coastal areas. Over time, the repeated collisions can cause rocks to chip, crack, or break into smaller pieces. This is an example of how the physical forces of moving water can contribute to the weathering and erosion of rocks.
