1 Plate Tectonics Ingrid & eliana

2 Who proposed and different kinds of evidence Alfred Wegener Evidence – fossils, glaciers, mountains, the continents fit together

3 Types of convergent plate boundaries Ocean-ocean Ocean-continent Continent-continent Features in common mountains and earthquakes

4 Types of divergent plate boundary Ocean-ocean Continent-continent Features in common Theres going to be a rift

5 Hot spot A volcanic activity That is made of hot solid material which rises from deep in Earths mantle.

6 PLATES Plates move 2 to 5 cm per year. About the same speed your fingernails grow In a million year it would move 25 km

7 Major names of plates There are 7 major plates- Pacific plate Indo-Australian plate The north American plate Eurasian plate African plate South American plate Antarctic plate

8 Question 1 Who proposed the continental drift ? a.Robert Ross b.Andrew Alford c.Alfred Wegener d. Nikki Minaj Answer : C Alfred Wegener

9 Question 2 How many convergent boundaries are there? Answer: C 3

10 G. Plate Tectonics Alfred Wegener proposed 4 Evidence are : a. Fossils b. Glaciers c. Mountains d. Continents fit together

11 Different types of convergent plate boundary are: a. Ocean-ocean b. Ocean-continent c. Continent-continent Features in common are: Mountains and earthquakes

12 Types of divergent boundary Ocean-ocean Continent-continent Features in common: Theres going to be a rift

13 Hot spot A volcanic activity That is made of hot solid material which rises from deep in Earths mantle

14 How fast plates move in a year They move as fast as your fingernails grow

15 Names of 5 earths major plates The north American plate Eurasian plate African plate South American plate Antarctic plate
