NGSS.MS-PS2-4

The process in which genetic variations among individuals in a population give some individuals an advantage in surviving and reproducing in their environment.

• Natural Selection

• Gravitational Force

• Metamorphic Rock

• Artificial Selection

NGSS.MS-LS4-4

Wear away or change the appearance or texture of (something) by long exposure to the air.

• Weathering

• Erosion

• Wavelength

• Inner core

NGSS.MS-ESS2-2

The force that pulls two objects towards each other. The force is affected by the amount of mass and distance: the greater the mass of an object, the greater the attraction; the farther apart the objects, the weaker the attraction.

• Gravitational Force

• Magnetic Force

• Natural Force

• Artificial Selection

NGSS.MS-PS2-5

Formed deep underground where heat and pressure cause existing rocks to be changed in both mineral composition and structural characteristics.

• Sedimentary Rock

• Igneous Rock

• Natural Selection

• Metamorphic Rock

Top layer of Earth made of the crust and the rigid, upper portion of the mantle that is broken into tectonic plates

• Inner core

• Outer core

• Lithosphere

• Crust

NGSS.MS-ESS2-3

Formed when lava or magma cools and solidifies. Lava cools quickly and forms rocks with small crystals, while magma cools more slowly and forms rocks with larger crystals.

• Metamorphic Rock

• Sedimentary Rock

• Rock Cycle

• Igneous Rock

Forms when particles of other rocks are deposited in layers and are compacted (crushed together), and cemented (binding of the sediments).

• Sedimentary Rock

• Metamorphic Rock

• Igneous Rock

• Rock Cyle

The number of wave cycles that pass a given point per unit of time.

• Amplitude

• Wavelength

• Frequency

• Waves

Newton's law states that for every action there is an equal and opposite reaction

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

• Law of Conservation of Mass
