​Earth's Sphere Key Concepts

  • When studying the Earth, scientists consider it a system of parts all interacting and working together. They divide this system into four (or five) spheres: atmosphere, biosphere, geosphere, and hydrosphere (and sometimes cryosphere).

  • ​The root of the words describe what is included in each category:

    • ​atmos = air = all of the gases surrounding the Earth

    • ​bio = life = all living (or once living) things

    • ​geo = land and rock = Earth's crust and landforms

    • ​hydro = water = all of Earth's oceans, lakes, rivers, etc.

    • ​cryo = ice = all of the frozen water

14

Multiple Choice

Gradual changes take___.

1

Moments

2

Days

3

Months

4

Hundreds and Thousands of years

15

Gradual Changes

  • Erosion (Wind, Rain, Gravity, and Ice)

  • Plate Movement (Plate Tectonics)

  • Mountain Formation (Plate Tectonics)

  • Island Formation (Volcanoes)

media

16

Catastrophic Changes

  • Earthquakes

  • Volcanic Erruptions

  • Hurricane

  • Tornadoes

  • Floods

  • Asteroid Impact

Catastrophic changes take___.

1

Moments

2

Days

3

Months

4

Hundreds and Thousands of years

18

Costal Erosion

  • Waves and currents erode away the rocks of the shore

  • Landforms: Sea Caves, Sea Arches, Sea Stacks, Fjords, Sea Cliff, Beaches

media

19

Multiple Choice

Is costal erosion catastrophic or gradual?

1

Catastrophic

2

Gradual

20

Mountain Formation

  • When a continental tectonic plate collides with another plate it is compressed and mountains form.

  • This takes Millions of years.

  • Examples: Andes, Rocky, Himalayan Mountains

media

21

Multiple Choice

Is Mountain formation catastrophic or gradual?

1

Catastrophic

2

Gradual

22

Flooding

  • When a river or lake flood the surrounding area.

  • Can cause major erosion of landforms

media

23

Multiple Choice

Is Flooding catastrophic or gradual?

1

Catastrophic

2

Gradual

24

River Erosion

  • Moving water Erodes away the rocks it passes.

  • Landforms: Ox Bow Lakes, Valleys, Delta

media

25

Multiple Choice

Is river erosion catastrophic or gradual?

1

Catastrophic

2

Gradual

26

Volcanic Island formation and Erosion

  • Volcanoes under the ocean erupt and create new crust.

  • Slowly this crust builds up until it makes an island.

  • Over Thousands of years the islands slowly erode back into the ocean.

media

27

Multiple Choice

Is Island formation and erosion catastrophic or gradual?

1

Catastrophic

2

Gradual

28

Meteor Impact

  • When a celestial object falls and crashes into Earth's Surface.

  • Creates an impact crater, sends a dust cloud into the sky that can block the sunlight causing plants and animals to die.

media

29

Multiple Choice

Is a meteor impact catastrophic or gradual?

1

Catastrophic

2

Gradual

30

Glacial Erosion

  • As the Ice Flows forward it scrapes away and smooths the land.

  • As the Ice Melts it forms Rivers and Lakes

  • Rivers flow faster as the ice melts

  • Glaciers melt and form lakes in a low spot
