Parts of the Atom

 The parts of an atom are protons,neutrons,and electrons.   The parts are arranged by protons and neutrons in the neucleus and electrons in the electron cloud.   You calculate neutrons by; Atomic mass{rounded} - Atromic Number = Neutrons.   

Rock cycle + Layers of the Earth

 Rock Cycle: an idealized cycle of processes undergone by rocks in the earth's crust, involving igneous intrusion, uplift, erosion, transportation, deposition as sedimentary rock, metamorphism, remelting, and further igneous intrusion.   Magma/Lava : Lava :hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this.   Magma:hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed by cooling.

 Layers of the Earth:The internal structure of the Earth is layered in spherical shells: an outer silicate solid crust, a highly viscous asthenosphere and mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core  Crust:: Crust. Crust: the outer layer of the Earth, between the surface and the mantle, which is up to 40 miles deep.  Mantle: Mantle: is the part of the earth between the core and the the crust is theMANTLE. It is about 1,800 miles(2,900 km) thick and makes up nearly 80 percent of the Earth's total volume.

Layers of the Earth Cont.

 Outer core: The outer core of the Earth is a fluid layer about 2,400 km (1,500 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Itsouter boundary lies 2,890 km (1,800 mi) beneath Earth's surface.  

 Inner Core:: The Earth's inner core is the Earth's innermost part. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 70% of the Moon's radius. It is composed of an iron–nickel alloy and some other elements.

Energy

    Potential EnergY   the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. EX: Bowling ball at top of hill.  

Kinetic Energy nergy that a body possesses by virtue of being in motion.
