• Earth's Crust
• The surface of the Earth is 71 water and 29
  land (we should have named our planet Ocean).

13

14

• Note that the crust is thin under the oceans,
  thick under mountains. The convective motion of
  the mantle under the thin spots causes sea floor
  spreading/continental drift.
• How do we know the continents are moving? Look at
  the fossil record.

15
The crust shaped by

• 1. impact cratering in the early solar system
• 2. erosion - wind, water, slumping (gravity) -
  most early cratering erased by erosion on planets
  with thick atmospheres
• 3. thermal-tectonic activity (plate tectonics) -
  outflow of heat from core transferred to
  convective motion in mantle.

16

17

• The motion is converted in linear motion of the
  crustal plates.
• There are 12 plates all floating on the mantle
  with speeds of a few cm per 100 years.

Effects of Salinity Experiment 1.3

• Supplies
• Clear Glass Jars (3)
• 3 Water samples
• Hydrometer

25

• Introduction
• To measure the salinity of water using a
  hydrometer.

26

• Procedure
• Pour the Samples of water into 3 different
• Glass jars.
• Place hydrometer into the first water sample.
• Take the hydrometer reading and record.
• Continue with the other water samples.
• Discard water samples safely and clean up.

27

• Observations
• Observed that the hydrometer readings .
