Which agents can cause cracks in rock formations over time?
Agents such as water, temperature fluctuations, plant roots, and pressure changes from tectonic forces can cause cracks in rock formations over time. Water is one of the most common agents, as it can enter cracks, freeze, and expand, causing the rock to crack further.
How does water entering spaces in limestone cause physical weathering?
Mainly through expansion of cracks and fissures from frost expansion which leads to further and deeper cracks and fissures. Plant roots seeking moisture may extend roots into limestone cracks and fissures, prying the rock apart.
Why a rock with many joints and cracks will be affected by frost weathering?
A rock with many joints and cracks will be affected by frost weathering because water can enter these openings and freeze. When water freezes, it expands, putting pressure on the rock and widening the cracks. Over time, repeated freezing and thawing cycles can cause the rock to break apart due to this expansion and contraction.
What are the causes of development of pot holes?
Pot holes are cracks or weaknesses in roads. If there is a crack/crevice in the road then water may enter and freeze over night, expanding the crevice. As this process repeats and the road is used more then the pot hole will expand in size.
How can water be an agent for mechanical weathering?
Water can enter cracks in rocks and freeze, expanding as it turns to ice and causing the rock to break apart. Water can also flow over rocks, carrying sediment and abrasive particles that wear away at the rock's surface through abrasion. Additionally, water can promote chemical weathering by reacting with minerals in the rock to weaken its structure.
What are two ways travels from land to enter the ocean?
Seepage from the ground and runoff from the surface.
What are bands of ore that form when minerals dissolved in water and enter cracks in rocks?
veins
What can develop from cracks caused to the breast from breastfeeding?
This creates a tiny opening in the breast, through which bacteria can enter.
Air enters the 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 happens to a sperm that does not enter the egg?
It will die!
What happens when sperm does not enter the vagina?
It dies.
Did Moses' sons enter the promised land along with him?
No, Moses' sons did not enter the promised land with him.
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 happens to light rays after they enter the pupil?
They die.
What does enter at your own risk mean?
You may enter, but its dangerous and you are personally liable for anything that happens after you enter.... (usually accompanied with a caution warning.)
When is a black snake most likely to enter a house?
A black snake is most likely to enter a house if there is an entrance way for the snake to get through. Buildings with cracks and small holes on the exterior are prone to vermin infestations.
What happens after cell division?
The new cells enter into interphase.
