Describe how changes in the temperature cause rock fragmentation?
Water seeps into the rock, and when it freezes, it expands. When it heats up again, the water goes farther into the rock, and so on until the rock breaks.
Which physical process weathers rock?
Wind, water, chemical, temperature changes,
Metamorphism involves what two conditions act on the existing rock to change it?
Metamorphism involves temperature and high pressure and chemical changes. The high pressure, chemical changes and temperature are the metamorphism that act on a rock that makes it change.
High temperature and pressure cause igneous rocks to become what type of rock?
Metamorphic rock
Does cohesion cause water to resist temperature changes?
high specific heat
What do changes in temperature cause rock to do?
Changes in temperature cause rock to expand and contract. This may cause them to crack, and pieces may break off.
How can changes in temperature cause rocks to erode?
The temperature heats the rock and breaks it (erodes).
Describe how changes in the temperature cause rock fragmentation?

How do changes in temperature cause rock fragmentation?
Rocks expand and contract depending on the temperature. After repeated exposure to temperature cycles, the surface of a rock may experience weakness in the bonds between crystals or particles, causing a delamination of the outer layer.
Why is sedimentary rock converted into metamorphic rock?
Sedimentary rock is formed generally at low temperature and pressure conditions.Therefore a change in this conditions to higher levels triggers mineralogical change.The driving forces for metamorphism are changes in temperature, pressure, and composition of the environment or strong deformation.These changes cause recrystallization in the solid state as the rock changes toward equilibrium with the new environment.Hence, formation of metamorphic rocks.
How do cyclones effect the atmosphere?
it can cause temperature changes
What is a major cause of temperature changes on earth?
The angle of the sun's rays is one of the major causes of temperature changes on Earth.
What forms as heat or pressure cause changes in an existing rock?
A "metamorphic" rock forms.
What factors cause changes in temperature during the seasons?
The Earth's tilt and orbit cause seasonal temperature changes.
When changes in pressure temperature or chimical make-up alter a rock what takes place?
metamorphic rock metamorphic rock, or metamorphism
What is the process that changes the characteristics of a rock?
Weathering and erosion would alter the shape of a rock, as would the application of stress possibly combined with high(er) temperature conditions.
When the temperature changes cause of a reaction is it exothermic or endothermic?
It is exothermic
