Earth has an inner core, outer core, mantle, and crust. Inner core is solid and made of iron and nickel. Outer core is liquid and made of iron and nickel. Mantle is made of molten rock called

Do you think that Earth (mainly the crust and continents) have always been the same or not?
- The Earth has always looked like this and have never changed
- Earth has changed in the past but it is no longer changing
- Earth has changed and will continue changing in the Future

In 1912, Alfred Wegner suggested that millions of years ago all the continents were joined together forming one large continent Over time, the land broke up and moved away. This was called

what is the evidence for the continental drift?

Why do some people reject the idea?

The shapes of the continents fit together 2. The types of rock on the different continents match up where they fir together. 3. The fossils on different continents match up where they fit together.

Movement of Earth crust cannot happen if the Crust is only one large piece This means that, in reality, Earth's crust is made of several Pieces (like a puzzle) which we call Tectonic Plates These Tectonic plates are floating on the Magma of the mantle and are moving slowly

Tectonic plates meet at the Plates Boundaries Due to the movement of Tectonic plates, many geological changes can happen, especially at the Plate boundaries where the plates meet Plates can move towards each other, away from each other and can even move against each other

Volcanoes are formed at the plate boundaries, when lava erupts from the earth mantle Some Volcanoes are active and may erupt at any time Some volcanoes are inactive/dormant which means they have not erupted in a long time Some volcanoes are extinct which means they will not erupt again

Earthquakes happen at plate boundaries when plates move against each other The Size of the earthquakes (Magnitude) vary and depends on how much does the rocks of the plate move
