When water in cracks and joints freezes and expands the rock is broken into angular fragments?

This process is known as freeze-thaw weathering. When water seeps into cracks or joints in rocks and freezes, it expands, causing the rock to break apart into smaller pieces due to the increased pressure. Over time, repeated freeze-thaw cycles can weaken and break down the rock.


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.


Why does hydraulic action occur on jointed rocks?

Hydraulic action occurs on jointed rocks because water can penetrate the cracks and joints in the rock, applying pressure to these weak points. Over time, the force of the water can cause erosion and the eventual breakup of the rock along these joints.


Does Water erosion occurs when water seeps into cracks or joints in rock and then freezes?

There are four types of water erosion. They are freeze-thaw, biological, chemical, and exfoliation erosion. Freeze-thaw erosion occurs when water seeps into cracks or joints in rocks and then freezes.


Is the wedging tree roots along natural joints in granite a chemical or mechanical?

Wedging tree roots along natural joints in granite is a mechanical weathering process. The roots grow into the cracks and crevices, exerting pressure as they expand, which eventually causes the rock to break apart. This process is physical rather than involving any chemical reactions.

Water works to expand joints in rocks because it expands as it evaporates true or false?

No. Water expands when it freezes, causing the rocks to crack and break.


Why do sidewalks have lined joints built into them?

because they expand and contract with heat.


Do you get shorter when you walk?

yes,only 0.88 millimeters because you joints compress. but don't worry, when you sleep your bones will expand again


What connects the ribs allowing them to expand and contract?

Yes in a sense, as you inhale the diaphragm becomes full of air and it expands, the rib cage houses the diaphragm.


Does concrete expand?

yes, that is why they put expansion joints on bridges. (: your welcomeyes, that is why they put expansion joints on bridges. (: your welcome


What is the purpose of a bridge?

Expansion joints. This allows the bridge to shift or the materials to expand and contract in the bridge. This means that if it gets heated up it expands so it needs a gap so it can move and not break the road!


Can the fluid between your joints evaporate when you get shocked?

Yes Indeed so you can be paralyzed if you get shocked too much.


Why are there gaps in the side walk?

The gaps that are put in place at the time of construction are called, "expansion joints". When concrete, and other materials, heat up, they expand. If concrete expands too much it will press against other sections of concrete and can break or "buckle". When sections of concrete press against each other too hard, sometimes two adjacent sections will press up, creating a dangerous condition for anyone walking on the sidewalk. Expansion joints give a little space for the concrete to expand before anything bad happens. Even with expansion joints, it's sometimes not enough.


Why is your height greater when you are lying?

Your spinal discs decompress and expand because they don't have to support the weight, making you taller. The joints in the legs and neck also do this to some extent.


Why are there gaps between the slabs of concrete pavements?

There are 2 reasons for that. Reason one: They can be expansion joints. In the winter the pavement contracts and in the summer it expands. these joints are generally gaps that go the whole way threw the pavement. Generally these joints are filled with some sort of caulking to keep moisture from getting underneath the pavement. Reason two: They can be put there as joints for the concrete to crack. when sidewalks are made and other concrete pavements, they anticipate the concrete cracking, so they put in gaps that dont go all the way threw the depth of the concrete as a place for the concrete to crack and not be unsightly.


Why are there gaps at regular spots in the side walk?

They're called "expansion joints". Concrete expands and contracts with temperature changes. The expansion joints allow this to happen without cracking the concrete slab.


What part of a skeleton system allow bones to move?

The ribs expand so that we can breathe. When the ribs expand, the volume of the pleural space increases and the lower pressure brings in air.
