Question
Earth’s surface is always changing. Some changes, caused by erosion, are ______. Some changes, caused by earthquakes, are _______. The Earth’s crust is like a puzzle. It is made up of huge pieces called __________ ______. The tectonic plates float on top of the mantle. The mantle is a soft, hot rock layer located between the _____ and the _____ ____. Heat is transferred from the core to the crust via _______currents (look at the arrows). Heat in the core causes magma to _______in columns in the mantle. The hot magma columns move the _______and then when the magma cools, it _______back towards the core.
The currents of hot _______pull and push the plates, causing the plates to smash together, _______apart, or grind past each other. This results in earthquakes, _______, and shapes many of Earth’s landforms.
The theory of Plate _______was defined in the 1970s. It follows Alfred Wegener’s 1912 theory of continental drift. He believed the _____ were once one landmass. The landmass split apart and moved to their current locations. His evidence was the _______of the continents which suggests they were once joined. _______are found in similar locations across multiple continents _______where the organisms would be found if the continents were once joined. This was a first step towards the _______tectonics theory.
Tectonic plates are either Oceanic Plates or Continental Plates. Oceanic plates are primarily ocean _______. They are _______and mostly made of _______rock. Continental _______rise above sea level. They are _______dense and made mostly of _______. Plates can move towards each other, _______from each other, or _______past each other. Plates only move 3-5 cm per year, which makes their normal movement impossible to observe.
A _______plate boundary occurs when two plates push together. When two _______plates collide high mountains, such as the Himalayas or Andes, can be formed. When two plates of different densities collide, such as a continental plate and an _______plate, _______occurs. The denser plate (oceanic) sinks beneath the _______dense plate. _______are frequently found at convergent boundaries.

Earth’s surface is always changing. Some changes, caused by erosion, are **slow**. Some changes, caused by earthquakes, are **fast**. The Earth’s crust is like a puzzle. It is made up of huge pieces called **tectonic plates**. The tectonic plates float on top of the mantle. The mantle is a soft, hot rock layer located between the **crust** and the **core**. Heat is transferred from the core to the crust via **convection** currents (look at the arrows). Heat in the core causes magma to **rise** in columns in the mantle. The hot magma columns move the **plates** and then when the magma cools, it **sinks** back towards the core.
The currents of hot **magma** pull and push the plates, causing the plates to smash together, **slide** apart, or grind past each other. This results in earthquakes, **volcanoes**, and shapes many of Earth’s landforms.
The theory of Plate **Tectonics** was defined in the 1970s. It follows Alfred Wegener’s 1912 theory of continental drift. He believed the **continents** were once one landmass. The landmass split apart and moved to their current locations. His evidence was the **shape** of the continents which suggests they were once joined. **Fossils** are found in similar locations across multiple continents **where** the organisms would be found if the continents were once joined. This was a first step towards the **plate** tectonics theory.
Tectonic plates are either Oceanic Plates or Continental Plates. Oceanic plates are primarily ocean **basalt**. They are **dense** and mostly made of **basalt** rock. Continental **plates** rise above sea level. They are **less** dense and made mostly of **granite**. Plates can move towards each other, **away** from each other, or **slide** past each other. Plates only move 3-5 cm per **year**, which makes their normal movement impossible to observe.
A **convergent** plate boundary occurs when two plates push together. When two **continental** plates collide high mountains, such as the Himalayas or Andes, can be formed. When two plates of different densities collide, such as a continental plate and an **oceanic** plate, **subduction** occurs. The denser plate (oceanic) sinks beneath the **less** dense plate. **Volcanoes** are frequently found at convergent boundaries.
The currents of hot **magma** pull and push the plates, causing the plates to smash together, **slide** apart, or grind past each other. This results in earthquakes, **volcanoes**, and shapes many of Earth’s landforms.
