What else can I help you with?
Rocks created by changes in temperature and pressure or the presence of hot watery liquid?
Metamorphic rock
How do changes in temperature cause rocks to break down?
Changes in temperature cause rocks to undergo thermal expansion and contraction. When rocks heat up, they expand; likewise, when they cool down, they contract. Over time, this repeated expansion and contraction weaken the rock structure, creating cracks and fractures that eventually lead to rock breakdown.
Physical weathering is greatest under conditions of?
Physical weathering is greatest under conditions of frequent temperature changes and the presence of ice. This is because the expansion and contraction of rocks due to temperature changes, as well as the freezing and thawing of water in rock cracks, can lead to the breakdown of rocks into smaller pieces.
Which physical processes result in the formation of metamorphic rocks?
Metamorphic rocks form when existing rocks undergo changes in temperature and pressure due to processes such as tectonic plate movement, burial deep within the Earth's crust, or contact with hot intrusions. These changes cause the minerals in the existing rocks to recrystallize and reorganize, leading to the formation of metamorphic rocks.
What are changes to rocks over wide areas called?
Changes to rocks over wide areas are called regional metamorphism. This process occurs under high temperature and pressure conditions deep within the Earth's crust, leading to the transformation of the mineral composition and texture of the rocks.
How can changes in temperature cause rocks to erode?
The temperature heats the rock and breaks it (erodes).
What is the natural process by which atmospheric and environmental agents sucj as wind rain and temperature changes disintegrate and decompose rocks?
the temperature
How might changes in temperature help form soil?
Changes in temperature can cause physical weathering of rocks through freeze-thaw cycles. During freezing, water in the cracks of rocks expands and exerts pressure, breaking the rocks into smaller pieces. Over time, these broken rocks mix with organic matter to form soil.

What does the word weathered mean?
Weathering in geology means the chemical and mechanical breakdown of rocks that occurs due to the weakening of these rocks by changes in the environment, such as temperature.
What type of weathering occurs when the extreme temperature from forest fires split rocks?
Thermal weathering occurs when rocks are exposed to extreme temperature changes, such as those from forest fires. The rapid heating and cooling of rocks causes them to expand and contract, eventually leading to the splitting and fracturing of the rocks.
How does the presence of water affect the melting temperature of rock?
The presence of water lowers the solidus temperature of rocks at a given pressure. It drastically changes the melting temperature by a vast amount.
Does temperature changes cause chemical weathering?
Yes, temperature changes can cause chemical weathering by expanding and contracting rock materials, leading to the breakdown of minerals and weakening of rocks. For example, freezing and thawing cycles can cause rocks to crack and break apart, accelerating the chemical weathering process.
High pressure and high temperature cause rocks to?
High temperature and pressure can cause rocks to change their forms. This is known as metamorphic.High pressure and high temperature can cause rocks to change forms. This is known as metamorphic.

This is because the expansion and contraction of rocks due to temperature changes, as well as the freezing and thawing of water in rock cracks, can lead to the breakdown of rocks into smaller pieces.
