Which processes change sedimentary rocks into metamorphic rocks?
Sedimentary rock may be broken down into sediment once again by weathering and erosion. It may also form another type of rock. If it becomes buried deep enough within the crust to be subjected to increased temperature and pressure, it may change into metamorphic rock.
What is one way that sedimentary rock can change through the rock cycle?
Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals.
What are the four types of chemical weathering?
There are different types of chemical weathering processes, such as solution, hydration, hydrolysis, carbonation, oxidation, reduction, and chelation. Some of these reactions occur more easily when the water is slightly acidic.
What are the 4 factors affecting the rate of reaction?
Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
How does a catalyst speed up a reaction?
A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions.
Which catalyst is more effective?
The most effective catalyst of all is the enzyme catalase, present in blood and intracellular fluids; adding a drop of blood to a solution of 30% hydrogen peroxide induces a vigorous reaction.
Why catalyst is finely divided?
A finely divided catalyst increases the rate of attainment of equilibrium and the incoming gases are purified before entering the catalyst chamber in order to avoid poisoning the catalyst. The unreacted gases are then passed through the reaction chamber again maintaining a continuous circulation.
