Quick Review1. The name for the

supercontinent in which all of the Earth’s continents were connected:

Pangaea

2. About how far do tectonic plates move in one year?

Just a few centimeters

Quick Review3. How old were the fossils of the

Mesosaurus that were found?

280 million years

Quick Review4. Based on the table, is it possible that Africa

and South America were once connected? Explain.

Yes, they were probably connected because Mesosaurus fossils were found in both locations even though they are thousands of miles apart today.

Quick Review5. Based on the information in the table, do

you think the Cynognathus would be found in South America? Explain.

Yes, because South America and Africa were once connected.

Objectives

BY THE END OF THE DAY YOU WILL:

1.Be able to describe the types of convergent plate boundaries.

2.Be able to identify the landforms which occur at those boundaries.

Essential Question

What happens when the surface of the earth moves?

Is the Earth one solid rock?

1. Boundaries are the spots were two plates meet

2. Convergent Boundaries: where two tectonic plates are moving toward one anothera.The word converge

means come together.

Types of crust (or plates)

Continental- They have land on them

Oceanic- Completely underwater

Convergent boundaries3. There are three different

types of convergent boundaries.a.Oceanic – oceanic =

two plates with oceanic crust are colliding.

b.Oceanic – continental = a plate with oceanic crust is colliding with a plate with continental crust.

c.Continental – continental

Convergent Continued

c. Mountains form at continental- continental convergent boundaries

Convergent Cont.4. Underwater

convergent boundaries form trenches.a.A trench is like a deep

ditch in the seafloor.

Convergent Cont. 5. Convergent

boundaries on land form mountain ranges.

Guided Practice

Guided Practice

1. Label the type of convergent boundary shown below.

2. Put a star next to the image(s) that show a boundary where trenches form and a dot next to the image(s) that show a boundary where mountains form.

Video

While you watch make observations about convergent plate boundaries.

After, draw a conclusion about our essential question: What happens when the surface of the earth moves?

I-N-D-E-P-E-N-D-E-N-T

“I do my own work!”

DO YOU KNOW WHAT THAT MEANS?

Notes away, mouths closed.
