|
Give 2 reasons why you don't notice the land moving beneath you? (think of reference points)
|
Two reasons why we don't notice the land moving beneath us is because ew are standing on it s oyou use it as a reference so you don't notice it moving. Also because your standing on it.

Suppose you are studing the motion of one of th e Earts plates. What units would you probably use to describe it's speed?
|
If you are studing a plate on Earth the units I would use t odescribe its speed is that it moves so slow and because it doesn't move great distances.
|
|
|
A certain plate moves 5mm in 100 days. What is the speed in mm/d? what is it's speed in mm/yr?
|
The speed for it in mm/d is 0.5 mm/d and 18.35 mm/yr.

|
what is a plate?
|
One of te major pieces that make up Earth's upper layer.
|
|
|
How do you solve a problem to figure out mm/d. and mm/yr. ?
|
1. set up the problem-
-x-=- 2. choose a conversion factor- 2mm over 1 yr times 1yr. over 365 days = 3.Multiply and solve if you have 2 divide type up 1 |
