What is water that fills tiny cracks and holes in the rock layers below the earth surface?
Groundwater, which may be either fresh or saline depending on location.
Air enters the rock cracks?
Yes, air will enter rock cracks. But, if water fills the crack, during a deep freeze, the expansion of the water, as ice forms, will often widen the crack (even to split the rock).
What is freeze -thaw action?
Freeze-thaw action is when water seeps into a crack in a rock, as the temperature drops below freezing, the water freezes and expands causing the crack to enlarge. The ice then melts into water again as the temperature rises above 0 degrees C. This action is repeated until the rock breaks.
What does groundwater mean in the water cycle?
Large Underground deposits of water underneath the earth's surface.
Cytoplasm function in animal?
Cytoplasm is the fluid substance that fills the space between the cell membrane and the cellular organelles. The cytoplasm contains enzymes that control chemical reactions inside cells.
What happens first rocks break apart or water fills tiny cracks in rocks and freezes or ice pushes against rocks?
All rocks have cracks in them. If water fills the cracks and freezes, it expands and pushes the rock apart.
What is an agent of chemical weathering?
Agents of chemical weathering depend on the climate and composition of the rock that is breaking down. Some Agents would include, water, oxygen, CO2, and acids. Temperature plays a significant role in chemical weathering. If it is warm and wet, the Chemical weathering process will increase. So, really it all depends.
Do rocks crack if they are subject to many hard frosts?
yes, frost is thicker than water, so as the water fills in the microscopic cracks and freezes, the cracks grow and grow until eventually it splits, then those split, then those, and it goes on until the rock is microscopic peices
What is the underground water that fills openings in soil and cracks in layers of rock?
The underground water that fills opening in soil and cracks in layers of rocks is called ground water.
What are some examples of mechanical weathering?
One example is when it rains, and there is a crack in the road. When the crack fills up with water it freezes and the crack will expand. Other examples are ice wedging, abrasion, exfoliation, and thermal expansion.
The underground water that fills openings in soil and cracks in layers of rock is called?
The underground water that fills opening in soil and cracks in layers of rocks is called ground water.
How are rocks weathered by frost action?
Rocks are weathered by frost action when water fills in a crack and freezes into ice causing the crack to expand. This weathers the rock this thaws the rock and greatly damages all of the weathering processes.
What is the term used by geoligests for water that soaks in the ground fills the openings in the soil and trickles into cracks and spaces in layers of rock?
The underground water that fills opening in soil and cracks in layers of rocks is called ground water.
Why are streets and highways damaged so much more in winter months than in the summer?
This is due to the cold weather that is typically experienced in the winter months. Water gets into small cracks in the road. When water freezes, it expands, causing the crack to widen. More water fills the new crack, freezes and widens it further. This cycle of freezing/melting/filling is what causes the damage to the roads.
What is the definition of groundwater?
the definition of groundwater is water that fills the cracks and spaces in underground soil and rock layers
What would one use a caulking gun for?
Caulking guns are used to fill in cracks around windows and bathtubs. This fills in the cracks and prevents water from getting in as the caulk is water resistant.
What is water that fills tiny cracks and holes in the rock layers below the earth surface?
Groundwater, which may be either fresh or saline depending on location.
