What is a geologist?
100

What is a glacier?
100
The breakdown of rocks and minerals at or near the Earth's surface. There are two types of this process.
What is weathering?
100
The question asked when you run an experiment.
What is a Focus Question?
200
Any non living natural resource that makes up Earth, including soil and water
What are earth materials?
200
The processes by which rock changes into different kinds of rocks
What is the rock cycle?
200
A fan-shaped deposit formed at the mouth of a river?
What is a delta?
What is an alluvial fan?
200
The carrying away (transportation, movement) of weathered earth materials by water, wind, or ice.
What is erosion?
200
A representation of a process in the real world that scientists use to observe something that is too big or too small to observe directly.
What is a model?
300
Bits of dead plant and animals parts in the soil.
What is humus?
300
A property of minerals determined by resistance to scratching or the idea that one minerals can scratch another mineral.
What is hardness?
300
The land that gets covered by water from a stream or river during a flood.
What is a floodplain?
300
The process by which rocks are broken down by breaking and banging and abrasion.
What is physical weathering?
300
The angle of land over which water flows. This will affect the rate at which water flows.
What is slope?
400
Rock that is smaller than sand but bigger than clay.
What is silt?

This can produce relatively fast changes to a landscape, a mountain side can yield to gravity and tumble down in the valley below.
What is a landslide?
500
Rocks the size of grapes up to the size of golf balls.
What are pebbles?

The way the mineral reflects light is a property to help identify minerals.
What is luster?
500
A deep valley with steep sides eroded by a river.
What is a canyon?
What is a gorge?
500
We demonstrated this chemical weathering by putting rock samples in vinegar and observing the bubbles. We followed this by letting the vinegar evaporate.
What is acid rain?
500
A test we performed and observed the sand settle quickly followed by clay suspended in the water.
