Archipelago n A group of islands clustered together

Archipelago n A group of islands clustered together in an open expanse of sea or ocean

Bay n A small area of sea or lake partly enclosed by dry land

Cape n A pointed piece of land that projects from a coastline

Continent n One of the seven great masses of land on Earth

Continental Divide n A long mountain ridgeline that determines the directions a continent's rivers will flow

Delta n A fan-shaped deposit of mud and sand, often green with vegetation, found at the mouths of many rivers

Desert n A very dry and desolate land that receives little or no rainfall

Faults n The fracture or movement of rock strata

Fjord n A long narrow inlet of the sea between tall rocky cliffs

Geyser n A naturally hot, or geothermal spring that shoots scalding water and steam high into the air

Glacier n A great mass of ice slowly sliding down a mountain slope or through a valley (a very slow moving river of ice)

Gulf n A large inlet of ocean or sea that is partially surrounded by land (gulfs are much bigger and deeper than bays)

Headwater or Source n The area where a river originates and begins its journey to the sea

Iceberg n A large chunk of floating ice that has broken off from a glacier

Isthmus n A narrow strip of land that connects two larger areas of land, and narrowly separates two large bodies of water

Mountain Pass n An opening or gap in a mountain range that serves as a path or road across the mountains

Mouth n The place where a stream flows into a larger body of water - the end of a river

Ocean n The entire body of salt water that covers nearly three-quarters of the Earth's surface

Ocean Ridge n A massive mountain range lying at the bottom of an ocean or sea

Peninsula n A large piece of land that juts far out into the water and is almost surrounded by water

Permafrost n Soil that is permanently frozen

Plateau n A large highland plain that rises sharply above the surrounding land.

Rift Valley n A long, narrow valley lying between two normal geologic faults. This is a result of diverging continental plates. n The divergent plate boundary which extends southward across eastern Africa, is in the process of splitting the African Plate into two new separate plates. Geologists generally refer to these plates as the Nubian Plate and the Somali Plate. �

River Basin n The beginning points of several rivers and their tributaries

Sea n A large body of salt water that is smaller than an ocean

Sea Level n An average height of the world's oceans used as a measure of heights and depths

Strait n A narrow waterway that connects two larger bodies of water (these are also called channels)

Tributary n A small running stream of water that flows into a larger river or stream

Polar, Temperate, and Tropical Zones n A broad belt of climate and geography that encircles the Earth

Tropical Zone n The hot, steamy region that lies just north and south of the equator

Temperate Zone n The two moderate regions that lie north and south of the tropical zone

Polar Zone n The ice-cold regions located at the north and south poles

Before beginning Science today, it is very important that you … WASH YOUR HANDS!!! - and yes, use SOAP!

Plate Tectonics What do you think of when you think of each of the following? n Oceanic n Continental n Convergent n Divergent n Transform

Turn to the corresponding handout in your Science Notebook What do you now think of? n n n Convergent Divergent Transform

Turn to the corresponding handout in your Science Notebook n n Read through the section titled Finding Faults with Food, SILENTLY, as you wait for your supplies. Talk to a partner to discuss what you notice.

Finding Faults With Food n n Using the supplies given, follow the directions carefully to make a food model of a DIVERGENT Plate Boundary. Talk to your partner about key things that should go into your model before you draw it. Draw and label a model of divergent plate boundaries Do NOT eat your supplies!

Finding Faults With Food n n Using the supplies given, follow the directions on the next page to make a food model of a CONVERGENT Plate Boundary. Remember that this first one will show Oceanic Crust converging with Continental Crust Talk to your partner about key things that should go into your model Draw and label a model of convergent plate boundaries

Finding Faults With Food n Using the supplies given, follow the directions on the next page to make a food model of a CONVERGENT Plate Boundary. n Remember that this first one will show Continental Crust converging with Continental Crust n Talk to your partner about key things that should go into your model Draw and label a model of this type of convergent plate boundaries n

Finding Faults With Food n n n Using the supplies given, follow the directions on the next page to make a food model of a Transform Plate Boundary. Talk to your partner about key things that should go into your model Draw and label a model of transform plate boundaries

Okay, now you can… n Eat your supplies
