Spheres of Earth
What is solid Earth and what are 3 examples?
Geosphere
Examples: Rocks, soil and mountains
The process of breaking rocks into smaller pieces is called?
Weathering
This is the thin outer layer. It has rocks and soil and we live on it.
Crust
This is an opening in Earth's crust where magma comes to the surface. When magma from these reaches the surface, it is called lava.
This is a deep valley with steep sides, it can have steep cliffs on its sides.
Canyon.
What is all of Earth's water and what are 3 examples?
Hydrosphere
Examples: Rivers, oceans and lakes
Give some examples of weathering.
Water enters cracks in rocks and breaks them apart.
Plant roots can grow into the cracks of rocks to break them apart.
Wind and moving water can wear down rocks into smaller pieces over time.
This is a very thick layer, is below the crust, and is made of hot rock than moves slowely.
Mantle
This is a steep rock face or a very steep side of land.
Cliff
This land rises high above the land around it.
Mountain
What are gasses surrounding the Earth and what are 3 examples?
Atmosphere
Examples: Air, wind, clouds
What is it called when sediment (dirt or rocks) is carried from one place to another?
Erosion
This layer is mostly made of liquid metal and is very hot.
Outer Core
This is a natural hollow opening inside of rocks or underground.
Cave
This landform is surrounded by water.
Island
What are all livings things and what are 3 examples?
Biosphere
Examples: Plants, animals and humans
The movement of weathered rock from one place to another and is dropped in a new place is called?
Deposition
This is the inner layer made mostly of solid metal.
Inner Core
What is a natural feature of Earth's surface is called?
Landform
How can an island form?
Volcanic activity, or by other processes that change Earth's surface.
Explain how the spheres interact.
Rain falls from clouds in the atmosphere on a mountain in the geosphere.
Water can move the soil, but plant roots in the biosphere can help hold soil in place.
The rain then enters the hydrosphere.
What are some agents of Erosion?
Water
Wind
Ice
Gravity
What is the order of layers of Earth?
Crust -> Mantle -> Outer Core -> Inner Core
How do some caves form?
Water can slowly dissolve rock leaving behind a cave.
How can a mountain form?
From volcanic activity or when Earth's crust moves.
