Spring Semester Exam Review part 1

Nothing is being tested

Will the mass of the pendulum affect the time it will take it to swing 20 times?

Will the distance the string is pulled back affect the time it will take the pendulum to swing 20 times?

Will the length of the string affect the time it will take the pendulum to swing 20 times?

Friction

Gravity

Balanced Forces

Air resistance

Comparative, because it is comparing the length of the string

Descriptive, because it describing the amount of time it takes to complete 20 swings.

Comparative, because it is comparing the mass of the pendulum

Experimental, because it has an independent and dependent variable.

Sea floor spreading is where new sea floor is destroyed. You would find a mid-ocean ridge at a divergent boundary

Sea floor spreading is where a mid-ocean ridge is created at a convergent boundary under the ocean floor.

Sea floor spreading is where new sea floor forms, pushing existing rock in opposite directions. You would find a mid-ocean ridge at a convergent boundary

Sea floor spreading is where new sea floor forms, pushing existing rock in opposite directions. You would find a mid-ocean ridge at a divergent boundary

Divergent- a boundary in which two plates are coming together. Transform- a boundary in which two plates are pulling away from each other. Convergent- boundary in which two plates are sliding horizontally past each other

Transform- a boundary in which two plates are coming together. Convergent - a boundary in which two plates are pulling away from each other. Divergent- boundary in which two plates are sliding horizontally past each other

Oceanic-Oceanic Convergent, Oceanic-Continental Convergent, Continental-Continental Convergent

When two or more substances react and an unknown substance is created

When chemical bonds are broken and matter is lost or gained

The process in which atoms are rearranged to produce new substances; the bonds that hold atoms together may be formed or broken.

only occur when an explosion takes place

covalent

ionic

complex

metallic

Helium has only 1 proton

Helium has a complete set of 8 valence electrons

Helium has two valence electrons in its first and only energy level.

Helium is a metal, while the rest of the noble gasses are nonmetals

Position B

Position A

Position D

Position C

The process that causes earthquakes and transform boundaries

The process by which rock is broken down into smaller particles

The process in which rock, sediment, and soil are transported from one place to another

The process by which sediment is deposited in a new location

Exothermic - a chemical reaction that requires an input of energy - energy is taken in during the reaction. Endothermic - a chemical reaction in which energy is released to the surroundings - energy is given off in several forms (light, heat, sound, etc)

Endothermic - a substance that slows down or stops a chemical reaction; Exothermic - a substance that speeds up the rate of a chemical reaction.

Endothermic - a chemical reaction that requires an input of energy - energy is taken in during the reaction. Exothermic - a chemical reaction in which energy is released to the surroundings - energy is given off in several forms (light, heat, sound, etc)

Neither substance causes any change to a chemical reaction

Valence electrons are the electrons in the outermost energy level. They tell us the element's reactivity.

They are always equal to the number of protons and therefore identifies the element

They determine what the element is

They are the total number of electrons that an atom has and they determine where an atom is located on the periodic table

Convergent- a boundary in which two plates are coming together. Divergent- a boundary in which two plates are pulling away from each other. Transform- a boundary in which two plates are sliding horizontally past each other

all form at mid-ocean ridges

Wherever you find plate boundaries

Folded mountain- at a convergent boundary where two plates push together, Fault-block mountains- There large pieces of rock break due to tension at divergent boundaries, Volcanic mountains- When plates collide and one plate subducts under another, allowing magma to push up to the surface. Also at divergent boundaries at mid-ocean ridges, Subduction zone- at oceanic-oceanic or continental-oceanic convergent boundaries. The denser plate subducts, or goes under the less dense plate, Mid-Ocean Ridge- These are found at divergent boundaries where crust is pulled apart and sea-floor spreading is happening, Trenches- found at subduction zones as one plate goes under another, Rift Valleys- formed by divergent boundaries where crust is pulled apart forming shallow valleys
