What is the word for water going into rocks?
The process of water seeping or flowing into rocks is called infiltration. This occurs as water moves through the pores and cracks in the rock, eventually becoming groundwater.
Why do rocks have cracks?
Rain and running water can enlarge existing cracks in rocks through its erosive powers. Freezing water in a rock crack will expand, causing additional fracture.
Why does rainwater in polluted areas cause rocks to weather faster than they usually do?
Rainwater in polluted areas contains acidic compounds that can react with the minerals in rocks, causing them to break down more rapidly through a process known as chemical weathering. This acidic rainwater accelerates the dissolution of mineral grains in the rock, leading to faster weathering rates compared to areas with cleaner rainwater.
What kind of springs form where pressurized water flows through cracks in cap rocks?
Artesian springs form where pressurized water flows through cracks in cap rock.
What is magma that squeezes into vertical cracks between rocks and then hardens is called?
The magma that squeezes into vertical cracks between rocks and then hardens is called a dike. Dikes are tabular bodies of igneous rock that cut across the existing rock layers.
What is the movement of surface water into rocks or soil through cracks or pore spaces?
Infiltration is the movement of surface water into rocks or soil through cracks or pore spaces.
Why do rocks get worn down by the rain?
Rainwater contains weak acids that can chemically react with the minerals in rocks, causing them to break down over time through a process called chemical weathering. Additionally, the force of rain hitting the rocks can physically wear them down through a process called mechanical weathering. Over time, these processes can cause rocks to erode and change shape.
What are horizontal cracks in rocks called?
They are called bedding planes
Does rainwater cause physical weathering?
Yes, rainwater can cause physical weathering by contributing to the process of erosion. When rainwater falls on rocks, it can seep into cracks and crevices, freeze, and expand, leading to the breakdown of the rock over time. This process, known as frost wedging, can gradually wear down rocks and contribute to their physical weathering.
Give at least 5 factors that cause weathering of rocks and explain how?
Water: Water can seep into cracks in rocks, freeze and expand, causing the rocks to break apart through a process called frost wedging. Wind: Wind can carry abrasive particles like sand that abrade the surface of rocks through a process called abrasion. Temperature changes: Daily fluctuations in temperature can cause rocks to expand and contract, leading to cracking and eventually breaking apart. Plant roots: Plant roots can grow into cracks in rocks, exerting pressure as they expand, causing the rocks to break apart. Chemical reactions: Rainwater and groundwater can contain acids that react with minerals in rocks, causing them to dissolve and break down over time.
How can plants and ice break down rocks?
Plants can break down rocks through a process called "biological weathering," where their roots grow into cracks in the rocks, causing them to break apart as the roots expand. Ice can break down rocks through a process called "freeze-thaw weathering," where water seeps into cracks in the rocks, freezes, and expands, causing the rocks to crack and break apart.
How does ice effect rocks?
Ice can cause rocks to crack and break apart through a process called freeze-thaw weathering. When water seeps into cracks in rocks and freezes, it expands, putting pressure on the rock which can eventually cause it to break. Over time, repeated freezing and thawing can cause significant damage to rocks.

What is the cycle of freezing and thawing in cracks of rocks called?
ice wedges
Water freezes in the cracks in rocks. plants grow into the cracks in rocks?
cracks open wider

What example is given for explaining how rainwater can cause weathering?
An example of how rainwater can cause weathering is through a process called chemical weathering. Rainwater, which is slightly acidic due to carbon dioxide in the atmosphere, can dissolve minerals in rocks over time. This can weaken the rocks and lead to their eventual breakdown and erosion.
