What is solvent?
a substance, typically a liquid, that can dissolve another substance (the solute) to form a homogeneous mixture called a solution
100
Can we make solids dissolve faster?
YES
100
What is reactants?
the starting substances in a chemical reaction that are consumed and transformed into new substances called products
100
How is granite formed?
Granite is an intrusive igneous rock formed from the extremely slow cooling and crystallization of magma deep beneath the Earth's surface. Because the molten rock cools so slowly, the mineral grains have a long time to grow, resulting in the coarse-grained, speckled texture characteristic of granite.
100
Name types of soil
sand, silt, clay, and loam
200
What is solute?
a substance that is dissolved in a solvent to form a solution
200
What is physical change?
a change to a substance's form or appearance but not its chemical composition, meaning no new substance is created.
200
What is products?
the new substance or entity formed as a result of a chemical or physical transformation
200
Minerals inside crystaline? Name atleast one
Pyroxene, Micas, Feldspar, Oxygen, Silicate, Aluminum, Magnesium
200
TRUE OR FALSE
CLAY SOIL HAS
large, gritty particles and is coarse to the touch.
FALSE ITS SAND SOIL
300
Name an igneous rock
Basalt,Andesite,Granite,Pumice
,Rhyolite,Diorite,Gabbro

What is liquid golds boiling point?
2856 °C (5173 °F)
300
What is irreversible?
a permanent change where a substance cannot return to its original state, often because a new substance is formed through a chemical
300
Describe crystaline or whats cyrstaline
a solid material in which the atoms, molecules, or ions are arranged in a highly ordered, repeating pattern known as a crystal lattice. This ordered structure gives crystalline solids distinct physical properties, such as a sharp melting point and predictable cleavage.
300
is the process of transporting those pieces away
EROSION
400
What is golds melting point?
1,064 °C
400
how do we make solids dissolve slower ?
To make a solid dissolve slower, reduce the temperature of the solvent, increase the size of the solid pieces, and do not stir or agitate the solution. These methods slow down the particle movement and reduce the surface area available for dissolving, which decreases the overall rate of dissolution.
400
What is reversible?
a change or reaction that can be undone, returning the substance(s) to their original state.
400
Whats crystals?
When minerals cools down.
400
Name types of metamorphic rocks
Slate
Phyllite
Schist
- MarbleQuartzite
500
What's solidification?
Hint:
Unit 3 topic igneous rock LB
When magma cools it turns into a solid.
500
Whats extrusive igneous rock?
Some of the magma comes out at the surface as lava. when lava cools down, it solidifies into an extrusive igneous rock.
500
What are materials or substances that are able to conduct electricity?
metals like copper, silver, and gold; non-metals like graphite; and solutions containing dissolved ions, such as tap water.
500
What is intrusive igneous rock?
forms when magma cools and solidifies deep within the Earth's crust, resulting in a coarse-grained texture with large, visible crystals.
500
What is rock cycle?
The rock cycle is the continuous process through which the three main types of rocks—igneous, sedimentary, and metamorphic—transform from one type to another over geologic time. These changes are driven by processes like melting, cooling, weathering, erosion, heat, and pressure, which are all influenced by Earth's internal heat and energy from the sun
