Warm Up, November 4th, 2014 What are the benefits of one of you teaching class? What are the cons? (educational answers only) What was the purpose of yesterday’s activity/lab? What would a creature that lives in the intertidal zone need to be adapted to in order to live there? What about a creature in the neritic zone? Deep?

Phytoplankton* - Microscopic organisms that inhabit the upper, sunny layers of oceans and most fresh water. Phytoplankton produce most of the world’s oxygen.

The Three Zones – Intertidal Zone* Animals and plants must be able to live in wet and dry conditions Zone with most sunlight

Because of the tides, waves, & predation, shoreline creatures can fly high or dig down low. Or wait it out…

What causes the tides?

What causes the tides? The tides are caused by the Sun and the moon having a tug-o-war with the Earth as rope!

The tides are the sun & the moon having a tug-o-war with the earth (gravitationally speaking).

Why doesn’t the sun pull the earth hard enough to negate the moon Why doesn’t the sun pull the earth hard enough to negate the moon? The sun has much more mass after all…
