What are the processes that may act upon rocks and cause them changes?
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.
Do objects in motion always change position and may change direction?
Objects in motion continuously change position.To change direction, a force needs to act upon them.
How does genetic recombination influence how species change over time?
The genetic variation introduced during recombination provides new allelic combinations for natural selection to act upon.
What environmental agents act to break down rocks and minerals into smaller pieces?
Weathering agents such as water, wind, ice, and living organisms can break down rocks and minerals into smaller pieces through physical (mechanical) and chemical weathering processes. These agents can contribute to the erosion and dissolution of rocks over time, leading to the formation of sediments.
Where do metamorphism rocks form?
where do metamorphic rocks form, the mantle crust or core?Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks. How do sedimentary and igneous rocks change? The rocks are under tons and tons of pressure, which fosters heat build up, and this causes them to change. If you exam metamorphic rock samples closely, you'll discover how flattened some of the grains in the rock are. this is how they are formed.
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).

What acts on a rock to change its shape or volume?
Forces such as compression, tension, and shear can act on a rock to change its shape or volume. Compression squeezes rocks together, tension stretches rocks apart, and shear causes rocks to slide past each other. Additionally, weathering and erosion processes can break down rocks and reshape them over time.
What are the factors that act together on rocks to form soil?
Factors that act together on rocks to form soil include weathering processes (physical, chemical, biological), organic matter accumulation, and time. Weathering breaks down rocks into smaller particles, organic matter enriches the soil with nutrients, and time allows for the transformation of rocks into soil through these processes.
Name two external processes?
External processes affect the surface of the Earth and include flooding.
How does mechanical weathering increase surface area of rocks?
Mechanical weathering breaks down rocks into smaller pieces through processes such as frost wedging, root wedging, and abrasion. As the rocks are broken down, their surface area increases because there are more exposed surfaces on the smaller pieces. This increased surface area allows for further weathering processes to act on the rocks, leading to their continued breakdown.
Is thrown rocks physical change or a chemical change?
Throwing rocks is a physical change because it does not alter the chemical composition of the rocks. The act of throwing simply changes the position and motion of the rocks, but the rocks themselves remain unchanged chemically.
Do objects in motion always change position and may change direction?
Objects in motion continuously change position.To change direction, a force needs to act upon them.
Explain how plants can act as agents of both mechanical and chemical?
Plants can act as agents of mechanical weathering through root growth that exerts pressure on rocks, causing them to break apart. They can also contribute to chemical weathering by releasing acids or organic compounds that break down minerals in rocks over time. These processes can help break down rocks and contribute to soil formation.
What is compressional energy?
Compressional energy refers to the energy associated with the compression or squeezing of materials. It is a form of mechanical energy that arises when forces act to reduce the volume or change the shape of an object or substance. Examples include the energy stored in springs when they are compressed or in rocks during tectonic processes.
What is to act upon and influence something?
when you act upon something and how you influence it like either you now your in trouble and you do something bad to try to get in more trouble.
What is an insipring quote?
A quote which motivates or inspires someone to act upon it, to change their way of thinking or behaviour on a particular matter.
