What are glaciers?
Your lab states that glaciers move under the force of two things…what are they?
Explain 2 ways that glaciers erode rock.Give 3 examples of glacial erosional features.Slide3

Describe the 2 different ways that glaciers move. (think of what you modeled in lab part 1 and 2)
Did the middle of the sides of the glacier move faster? Explain.Slide4

Lab!) cont’d 5//12*Hint: If your time doesn’t equal whole minutes, you’ll need to convert seconds to decimals. Divide leftover seconds by 60 to get decimals: Ex: 2 min 25 sec = 2.42 minPart 1: Calculate the speed that your glacier moved outward using the formula: Final width (cm)

______________ - _____________ = ______________ cm
Distance
(cm) / Time (min)
= Velocity
(cm/min)
__________cm / 2 min = __________ cm/minSlide5

Divide leftover seconds by 60 to get decimals: Ex: 2 min 25 sec = 2.42 minPart 2: Calculate the speed that your glacier moved outward using the same formula as above: 15 cm / __________min= ______________ cm/min
