Transcript Archipelago
Archipelago A group of islands clustered together in an open expanse of sea or ocean Bay A small area of sea or lake partly enclosed by dry land Cape A pointed piece of land that projects from a coastline Continent One of the seven great masses of land on Earth Continental Divide A long mountain ridgeline that determines the directions a continent's rivers will flow Delta A fan-shaped deposit of mud and sand, often green with vegetation, found at the mouths of many rivers Desert A very dry and desolate land that receives little or no rainfall Faults The fracture or movement of rock strata Fjord A long narrow inlet of the sea between tall rocky cliffs Geyser A naturally hot, or geothermal spring that shoots scalding water and steam high into the air Glacier A great mass of ice slowly sliding down a mountain slope or through a valley (a very slow moving river of ice) Gulf A large inlet of ocean or sea that is partially surrounded by land (gulfs are much bigger and deeper than bays) Headwater or Source The area where a river originates and begins its journey to the sea Iceberg A large chunk of floating ice that has broken off from a glacier Isthmus A narrow strip of land that connects two larger areas of land, and narrowly separates two large bodies of water Mountain Pass An opening or gap in a mountain range that serves as a path or road across the mountains Mouth The place where a stream flows into a larger body of water - the end of a river Ocean The entire body of salt water that covers nearly three-quarters of the Earth's surface Ocean Ridge A massive mountain range lying at the bottom of an ocean or sea Peninsula A large piece of land that juts far out into the water and is almost surrounded by water Permafrost Soil that is permanently frozen Plateau A large highland plain that rises sharply above the surrounding land. Rift Valley A long, narrow valley lying between two normal geologic faults. This is a result of diverging continental plates. 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 The beginning points of several rivers and their tributaries Sea A large body of salt water that is smaller than an ocean Sea Level An average height of the world's oceans used as a measure of heights and depths Strait A narrow waterway that connects two larger bodies of water (these are also called channels) Tributary A small running stream of water that flows into a larger river or stream Polar, Temperate, and Tropical Zones A broad belt of climate and geography that encircles the Earth Tropical Zone The hot, steamy region that lies just north and south of the equator Temperate Zone The two moderate regions that lie north and south of the tropical zone Polar Zone 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!

Convergent Divergent Transform Turn to the corresponding handout in your Science Notebook 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 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 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 Using the supplies given, follow the directions on the next page to make a food model of a CONVERGENT Plate Boundary.
