What is metamorphic rocks?
Metamorphic rocks are pre-existing rocks that have been transformed by intense heat, pressure, or chemically reactive fluids deep within the Earth.
What is sedimentary rocks?
Sedimentary rocks are formed on the Earth's surface from the accumulation of pre-existing rock fragments, mineral grains, or the remains of once-living organisms.
What is Chemical change?
process where substances transform into new substances with different properties
Cooking and egg
Irreversible
Describe metamorphic rocks.
Metamorphic rocks are formed from existing rocks (igneous, sedimentary, or other metamorphic rocks) that have been transformed by intense heat, pressure, or hot fluids.
Describe 3 about sedimentary rocks.
Sedimentary rocks form from accumulated sediments (rock fragments, minerals, or organic matter) that are compacted and cemented into layers (strata) over time, often containing fossils, and are categorized into clastic, chemical, and organic types based on their origin.
What is Physical change?
alters a substance's form or appearance but not its chemical composition.
Dissolving sugar in water
Reversible
Describe 3 about metamorphic rock.
Metamorphic rocks are formed from existing rocks transformed by intense heat, pressure, and/or hot fluids deep within Earth's crust, leading to changes in mineral composition and texture.
Give 3 examples of chemical changes.
rusting of iron, burning wood, and cooking an egg
Give 3 examples of Reversible and Irreversible.
Reversible: Melting ice, Dissolving sugar in water, and Folding paper.
Irreversible: Burning paper, Cooking an egg, and Rusting of iron.
