What are two elements of ocean basins?
Countries
Ocean basin
Landforms
Continents
State
What are large land masses called?
Sand
It is not flat, it has many continents that are much older than ocean basins. Some of these continents are billions of years old
It has features and forces
It has basins an dcontinents
Coral

What are the characteristics of the ocean floor?
Surface
Ocean basins
Continents
Which are older: continents or ocean basins?
No
Yes
Landforms are physical features on Earths surface
These features change over time
Some rocks on the continents are billions of years old
Yes they do due to two forces
Do features of the Earth changes over time?
Physical features change over time.
Landform
A feature next to the ocean floor
Landforms are physical features on Earths surface
Ocean basin
Landforms are physical features of the land around us, that appear on continents
A feature on the bottom of the sea
What is a landform?
Large stretches of connected land
Ocean floor
Landmass
Above sea level
Continents are large land areas
Deep trenches on the ocean floor
Continents are large land areas, that are mostly above sea level
What are continents?
They extend from the ocean basins
Landmass
They include the ocean floor and Earths deep ocean trenches
They extend from the ocean floor to the surface
Ocean basins extend from the edges of continents, include the ocean floor and Earths deep ocean trenches
Ocean basins extend from the edges of continents
Earths surface
What are ocean basins?
Basins
Landforms
Rocks
Continents
Terrain
What Earth features are mostly above sea level?
Two main features - Continents and Ocean Basins
There are basins and continents
Ocean

Surface
What does the Earth's surface consist of?
They are hundreds of years old
Old
Continents have rocks that are billions of years old; ocean basins may only be millions of years old
Ocean basins billions years old
Continents are millions of years old
Thousand years old
What are the ages of ocean basins and continents?
They have basins and levels
Billion years old
Have had a lot happen to them
They are bumpy and change
Above sea level
They are large land areas that are mostly above sea level. Ocean basins may only be millions of years old
Land areas
What are the characteristics of continents?
What if you could drain all of Earths oceans? What would it look like? You might be really surprised. You see that the surface has two main features. It has continents and ocean basins. Continents are large land areas. These are the areas that are mostly above sea level. Ocean basins extend from the edges of continents. They include the ocean floor and Earths deep ocean trenches. You will also notice the ocean floor is not flat. It too has many Continents are much older than ocean basins. Some rocks on the continents are billions of years old. Ocean basins may only be millions of years old. Because the continents are so old, a lot has happened to them! As we view the land around us, we see landforms. Landforms are physical features on Earths surface. These features change over time, but how? There are actually two types of forces at work.
