Earth's Crust: • The surface of the Earth is 71% water and 29% land (we should have named our planet Ocean).
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.
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.
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
Introduction: To measure the salinity of water using a hydrometer.
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.
Observations: Observed that the hydrometer readings ….
