How can you tell when rocks have been weathered rapidly from moving water over a long period of time?

• They round and smooth edges

• They have rough and flat edges

• Mrs. Hart likes them

• They are colorful

The breaking down of rocks into smaller pieces is...

• Magma

• Humus

• Erosion

• Weathering

Landslides are all of the following EXCEPT...

• Super Safe

• Earth materials including soil and rocks moving down a slope

• Rocks bumping into each other and then cause weathering

• Can be caused by overstep slopes, earthquakes, and rain

One benefit from a volcano can be...

• Damage to land

• Creation of habitats

• Creation of new land

• Release of steam

Lava can improve soil by...

• Mixing up the dirt

• Adding gas

• Removing bad things from the soil

• Leaving rich minerals in our soil

How are volcanoes and shaken soda bottles similar?

• Volcanoes and soda bottles are both dangerous.

• Soda will spill out over the top of a shaken soda bottle due to the gasses, just like magma spilling over the top of a volcano due to gasses.

• Earthquakes are similar to what happens when you open a shaken soda bottle.

• Soda bottles and volcanoes aren't similar at all.

All of the following are characteristics of earthquakes EXCEPT...

• Earthquakes are caused by plates of the Earth’s crust pushing against one another and when the plates break free the release of energy causes the “shake” or vibrations.

• Land is changed after an earth-quake

• Earthquakes cause quick changes

• There are several “lines” on Earth where faults are known.

• Earthquakes make playing fun
