What happens when fresh & salt water meet?

Estuary* When salt water and fresh water mix in a river, delta, or other source. 2 Types: - Mangrove Forest - Salt Marsh

MAYBE A FRESH WATER CROCODILE WANTS A SALTY MEAL IN THE SEA!

Maybe it wants a shark dinner!

Double the plant life!!!!!

Birds always have something to eat.

Birds have plenty of nesting sites too!

Estuaries have 2x life because 2 ecosystems are colliding!

Estuaries have 2x life because 2 ecosystems are colliding!

Estuaries: 2 X the breeding & feeding!

When Fresh rivers run into salty Ocean = estuaries

When fresh river water gets to the ocean, salinity (saltiness) increases

When ocean water pushes up river salinity (saltiness) decreases

salty/fresh mix = brackish

Look how lush & fertile an estuary looks from space!

2 types of estuary: SALT MARSH Atlantic Carolina coasts Stinky cord grass Absorbs tons of moisture MANGROVES Louisiana & gulf Hurricane proof trees Absorbs tons of moisture Great breeding grounds--nursery

In both pictures, the water is above the ground for some reason, and we know it is on top of soil. Why isn’t the water sinking if the soil is permeable?

So how does permeable layers affect your groundwater? Great breeding grounds--nursery

What happens to your water as it goes through different permeable layers? Gravel Soil Sand Which layer would you want your water to go through first? Which one last? Why? Clay

Water Filtration Lab three materials to filter out our ‘polluted’ water (food coloring, glitter, salt. Gravel, sand, sandy soil, clay, tissue The objective is to filter out all ‘pollution’ in the water. Hypothesis: Why? What Happened? Analyze, be specific.
