Weathering and erosion are processes that act upon rocks, breaking them down into smaller pieces and transporting them to new locations. Chemical reactions can also alter the composition of rocks, leading to mineral changes. Additionally, pressure and heat from geological processes can cause rocks to undergo metamorphism, changing their texture and structure.

What happens after physical and chemical changes have occurred?
The substance will remain in its current state unless acted upon in such a way as to cause a physical or chemical change.
Are pop rocks a chemical change?
Yes, popping candy like Pop Rocks undergoes a chemical change when it releases carbon dioxide gas upon contact with moisture in the mouth. The reaction between the candy ingredients and saliva causes the popping sensation and sound.
How does the melting and boiling point of a substance change?
it changes depending upon the temperature
what are igneous rock classified based upon?
Igneous rocks can be classified by their method of formation and by their mineralogy.
Why are metamorphic rocks created deep in earth's crust not on the surface?
Metamorphic rocks are formed deep in the Earth's crust because they require high pressure and temperature conditions that are typically found at depth. These conditions cause existing rocks to undergo physical or chemical changes, transforming them into metamorphic rocks. As these rocks move closer to the surface through tectonic processes like uplift and erosion, they can eventually be exposed for us to see.
What five processes act upon rocks to change them?
The five processes that act upon rocks to change them are weathering (breakdown of rocks into smaller particles), erosion (transportation of rock particles), deposition (settling of rock particles in new locations), heat/pressure (metamorphism), and melting/solidification (igneous processes).
The squeezing together of rocks by stress is called?
The squeezing together of rocks by stress is called compression. This compressional stress can cause rocks to deform and change shape due to the forces acting upon them.
Does a rock respond to the environment?
Rocks do not have the capability to actively respond to their environment. They undergo physical and chemical changes over time due to natural processes like erosion or weathering, but these changes are a result of external forces acting upon them rather than a conscious response.
What are rocks that hit the earth?
Rocks that hit the Earth from outer space are called meteorites. They can vary in size from small pebbles to large boulders and can cause impact craters upon entry into the Earth's atmosphere.
How the environment in which the business operates impacts upon its success?
The environment affects a business because changes can impact business strategy and processes. For instance, heavy government regulations can place a burden on the business.
What happens after physical and chemical changes have occurred?
The substance will remain in its current state unless acted upon in such a way as to cause a physical or chemical change.
How are the processes different?
Since there are billions upon billions of possible processes, this question is not within the human ability to answer. If you specify which processes you are talking about, that will make it answerable.
What bis physicalweathing and it causes?
Physical weathering represents the act of rocks, land, etc, breaking apart or breaking down. The physical weathering is caused by the changes of the temperatures upon the things experiencing the physical weathering.
Are pop rocks a chemical change?
Yes, popping candy like Pop Rocks undergoes a chemical change when it releases carbon dioxide gas upon contact with moisture in the mouth. The reaction between the candy ingredients and saliva causes the popping sensation and sound.
Why is it that rocks near the surface of the Earth tend to be brittle while those below tend to flow rather than break?
When a rock is subjected to increasing stress it changes its shape, size or volume. This is referred to as strain. In general, rocks near the surface of the earth behave in a brittle fashion. When they are acted upon by differential stress, they tend to fracture. Rocks that are below the surface are not subjected to the different "strains" then the rocks that are at the surface.
Does the composition of a sedimentary rock depend upon the composition of the rocks and the living things its sediments came from?
It is true that the composition of a sedimentary rock depends upon the composition of the rocks and living things its sediments come from. Sedimentary rocks form through lithification.
What are the two basic processes that life depends upon?
food and water
