Two noteworthy forms of weathering caused by extremes of weather conditions are:
- Freeze-thaw weathering:
- There is a natural fault/crack/bedding plane in the rock
- Water enters the crack
- Overnight, the water freezes and expands
- The expansion widens the crack, prying the rock apart, breaking it up.
- Ex-foliation:
- There is an outcrop of rock in an environment with a large diurnal range (i.e. a large temperature difference between day and night)
- During the day, the out-most layer of the rock expands more than the rest of the rock
- At night the out-most layer shrinks more than the rest of the rock
- Over time, the rock is weakened by constantly adapting in the heat, and eventually fragments to an extent that it just falls off.
What else can I help you with?
What rocks are formed by the effect of heat and pressure on other rocks?
the metamorphic rocks are formed by heat and extreme pressure from other rocks
Metamorphic rocks can be formed from sedimentary rocks by the activity of?
heat and pressure
Heat and pressure can cause some rocks to change into different types of rocks?
sedimentary rocks
How can a rock be metamorphic?
when the heat hits the different rocks its combinded with other rocks
What cause rocks to change form and become metamorphic rocks?
heat and pressure
What hold heat longer Rocks or water?
Rocks
Could heat melt rocks?
Yes heat could melt rocks
What rocks are formed by the effect of heat and pressure on other rocks?
the metamorphic rocks are formed by heat and extreme pressure from other rocks
Why do lizards lay on rocks?
As cold-blooded animals, lizards cannot produce their own body heat, so they need to obtain it from their environment. Rocks hold in heat much better than air, so lizards often lie on them to warm themselves.
What do rocks do under heat and pressure?
rocks can change form. There are three main types of rocks, sedimentary, Metamorphic and igneous. igneous. sedimentary rocks are rocks formed from sediment. Metamorphic rocks are rocks formed from heat and pressure. If other rocks are put under heat and pressure then they have a chance to change into metamorphic.
Rocks changed by heat and pressure?
metamorphic rocks
What factors control rocks returning to earths surface and becoming magma?
the heat of the volcano makes the rocks heat. the heat is the rocks the volcano blew up. now the rocks are a red hot liquid, the rocks rise to the surface because of the heat, it pops open the volcano top and makes a new island.
How does metamorphic rocks change into sedimentary rocks?
by heat & pressure
Can metamorphic rocks be produced by heat alone?
Yes. Proximity to a heat source can be enough to cause metamorphism of rock.
What can make Sedimentary Rocks and Igneous Rocks change into Metamorphic Rocks?
heat and pressure.
Igneous and sedimentary rocks are exposed to extreme pressure and heat They will most likely form?
If igneous rocks are exposed to extreme pressure and heat, they are likely to recrystallize into new igneous rocks. On the other hand, if sedimentary rocks are exposed to extreme pressure and heat, they are likely to metamorphose into metamorphic rocks.
Metamorphic rocks can be formed from sedimentary rocks by the activity of?
heat and pressure
