Net Force: The TOTAL amount of FORCE acting on an object.

Multiple Choice

Is this a balanced or unbalanced force?

• Balanced
• Unbalanced
• Neither
• Both

Multiple Choice

What is the net force of this object?

• 0N
• 50N
• 25N
• 5N

Multiple Choice

Plate Boundaries

Multiple Choice

A subduction zone is formed...

• when one tectonic plate sinks below another
• at every type of convergent plate boundary
• at every type of divergent plate boundary
• at transform boundaries

Multiple Choice

What is the theory of plate tectonics?

• The theory that describes how Earth's outer layers is broken up into moving tectonic plates

• Tectonic plates stay in one place

• All of the continents were once apart of a Super Continent called Panthalassa

• All of the plates were once a solid plate until they broke up and moved to their current position

Multiple Choice

What type of plates are colliding

• oceanic - oceanic plates

• oceanic - continental plate

• continental - continental plates

Multiple Choice

Why do volcanes form?

• From plate(s) getting stuck, pushed further, and folding
• From a plate subducting, melting, & rising
• From one plate being more dense & sinking creating a low spot
• All answers

Multiple Choice

The process of ___________ continually adds new crust to the ocean floor along both sides of the mid-ocean ridge.

• plate tectonics

• seafloor spreading

• continental drift

• convection

Multiple Choice

Why did the continental plate get volcanoes?

• It is made of thicker continental crust
• It gets stuck and folds
• It has a subducted plate under it that melts
• It is more dense

Multiple Choice

What kind of plate boundary is shown here?

• divergent
• convergent
• transform
• strike slip

Density

Density = Mass/Volume

Multiple Choice

Frank has an eraser. It has a mass of 4g, and a volume of 2cm³. What is its density?

• 8 g/cm³
• 2 g/cm³
• 1/2 g/cm³
• 24 g/cm³

Multiple Choice

Jack has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7 mL
• 7 g/cm³
• 28 g/cm³
• 1/7 g/cm³

Topographic Maps

Shows the ELEVATION of the land using contour lines. The Contour Interval is what EACH line changes by.

CLOSE LINES = STEEP SLOPE

FAR APART LINES = GENTLE SLOPE

Multiple Choice

What feature is at the arrow?

• volcano
• mountain
• cliff
• river

Multiple Choice

What is the contour interval on this map?

• 100
• 10
• 15
• 20

Multiple Choice

Which direction is the stream flowing?

• northward
• southward
• westward
• eastward

Multiple Choice

The height above sea level is called

• topographic
• contour
• elevation
• depth

Multiple Choice

When you move from one contour line to another, the elevation

• stays the same
• goes up or down
• disappears
• is below sea level

Multiple Choice

If contour lines are close together, then the slope is

• gentle
• steep
• flat
• going up and down
