Plate Tectonics Ingrid & eliana

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

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

Types of divergent plate boundary Ocean-ocean Continent-continent Features in common There’s going to be a rift

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

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

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

Question 1 Who proposed the continental drift ? Robert Ross Andrew Alford Alfred Wegener Nikki Minaj Answer : C Alfred Wegener

Question 2 How many convergent boundaries are there? 4 2 3 Answer: C 3

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

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

Types of divergent boundary Ocean-ocean Continent-continent Features in common: There’s going to be a rift

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

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

Names of 5 earth’s major plates The north American plate Eurasian plate African plate South American plate Antarctic plate
