Science 4: Geographical Features
Today we've got some geography. But that's not all, there are tons of extra features included free of charge. We've got rivers, lakes, deserts, mountains, and plateaus just to name a few. Watch in the next five minutes and we'll even throw in some islands.

Well, let's begin with water.
Water comes in tons of different forms on Earth.
Oceans, for instance, are large bodies of salt water, like the Atlantic and Pacific. [Oceans highlighted on a map of Earth]
Lakes, on the other hand, are bodies of fresh water surrounded by land, like Lake Ontario
and Lake Michigan.
Rivers are bodies of water that flow in a channel to another river, ocean or lake – like
the mighty Mississippi River or the Missouri River. [Mississippi and Missouri river highlighted]
Okay, so you probably knew all of those already, but did you know about…
If you said yes, then man, are you smart!
Maybe you should be narrating this video… [Two guys in class and one guy collapses to the floor]
Anyway, inland seas are large bodies of either salt or fresh water that are entirely surrounded
by land, like Hudson Bay.
And how about gulfs?
A gulf is a part of an ocean that is partly surrounded by land, like the Gulf of Mexico. [Gulf part of ocean in Mexico]
So much water, so many different geographic features.
And we haven't even gotten to land yet!
Seriously, can someone help us out here? [Woman wading through water]
We've been stuck at sea for a while…toss us a surfboard, or something…
Okay, now that we're on land…what kind of geographical features are we lookin' at….
Well, there are deltas, which are pieces of land shaped like triangles and created by
a split in a river. [Delta example of land]
There are islands, like Hawaii, which are pieces of land surrounded by water on all
sides….and also where we'd love to be right now, munching on a shave ice…yum. [Man eating an ice cream]
We've got plateaus– these are large flat areas of land that are higher than the areas
One famous example is the Colorado plateau.
And we've got deserts like the Mojave, which are areas of land that are dry and with little [The mojave desert]
Hm…maybe someone should open a shave ice stand there…
There are mountains – like Mount Denali - which are large natural elevations
of the surface of Earth…. [Mount Denali in the distance]
…And valleys like the Central Valley– which are low dips of land between hills or mountains.
So there ya have it!
The entire Earth is covered in a whole variety of different sorts of geographical features. [Coop discussing the different geographical features]
Can you think of any geographical features near your home or school?
Maybe a river, a lake, or even a mountain? [Mountain appears behind a house]
And no, your dad's belly doesn't count as a mountain, no matter how impressive it might be. [Dad with two ice creams walks through door]
