Earth's Layers
This is the outermost layer of the Earth that we live on.
The crust
This type of plate boundary is where two plates move toward each other and collide.
Convergent Boundary
This is the process where wind, water, or ice breaks down rock into smaller pieces over time.
Weathering
This natural event occurs when plates suddenly slip past each other, releasing energy as ground shaking.
An earthquake
This is the tallest mountain in the world, located in the Himalayas on the border of Nepal and China. Climbers travel from all over the world to reach its peak.
Mount Everest
This layer of Earth is made of hot, slowly flowing rock and sits just below the crust.Name the steps of the water cycle
The mantle
At this type of boundary, two plates slide past each other horizontally, often causing earthquakes.
Transform Boundary
When weathered material is carried away by water or wind to a new location, this process is called what?
Erosion
This opening in the Earth's surface allows hot magma, ash, and gases to escape from below the crust.
A Volcano
This massive canyon in Arizona, USA, was carved over millions of years by the Colorado River. It is one of the most visited natural wonders on Earth.
Grand Canyon
Earth's internal heat comes partly from this process, where unstable atoms break apart and release energy deep inside the Earth
Radioactive Decay
The Pacific Ocean sits mostly on this enormous tectonic plate.
The Pacific Plate
When two continental plates collide at a convergent boundary, they push upward to form these dramatic landforms.
Mountain Ranges
Yellowstone National Park is famous for these features, which shoot hot water and steam into the air due to geothermal heat.
Geysers
This enormous waterfall on the border of Canada and the USA is one of the most famous in the world and is a popular tourist
Niagara Falls
This is the very centre of the Earth. The inner part is solid despite being extremely hot, due to intense pressure.
When an oceanic plate collides with a continental plate, the denser oceanic plate sinks under — this process is called what?
Subduction
This flat, elevated landform is often formed by lava flows or by uplift from tectonic forces.
A Plateau
This event occurs when heavy rain or snowmelt causes a river to overflow its banks and cover surrounding land.
A flood
This coral reef system off the coast of Australia is the largest living structure on Earth and can even be seen from space. It is home to thousands of marine species.
The Great Barrier Reef
Convection currents in this layer are the main driver of tectonic plate movement on the surface.
At a divergent boundary, plates pull apart and magma rises to fill the gap, creating what kind of feature on the ocean floor?
Mid - Ocean Ridge
Rivers carry sediment and deposit it at their mouths, forming this fan-shaped landform over time.
A Delta
This slow geological process is currently widening the Atlantic Ocean by about 2.5 cm per year.
Seafloor spreading / divergent plate movement
This giant rock formation in Australia rises 348 metres out of flat desert land. It is sacred to the indigenous Anangu people and glows orange-red at sunset.
