New cards

volcanoes on Venus

  • surface is geologically active in some way

  • some volcanic activity

  • most volcanically active planet in solar system

  • likely released lots of gas (CO2) that caused irreversibly green house gas

2
New cards

evidence of recent volcanism

  • 1991: Maat Mons summit vents enlarged, changed shaper over 8-month period

    • evidence of direction abruption as space craft orbited Earth

    • re-examined radar data → scientists noticed volcanic activity

term image

  • most comprehensive volcanoes map

  • radar

  • 85,000 volcanoes of all sizes

4
New cards

volcanoes on Earth occurrence?

  • is not random, mainly occur on narrow bands along the plate boundaries

5
New cards

where do volcanoes occur on Earth?

  • where 2 tectonic plates collide or separate from each other

  • some occur in the middle of tectonic plate

6
New cards

result of some volcanos occurring in the middle of a tectonic plate?

  • different type of volcanism called Hot Spots

    • believed to be the type that resulted in Volcanoes in Venus

7
New cards

what are hot spot volcanoes?

  • consequence of mantle plums

8
New cards

where do hot spot volcanoes occur?

  • where lava erupts to the surface through the middle of tectonic plates

    • occur at abnormally hot areas called mantle plumes

  • DOES NOT occur on plate boundaries

New cards

when do hot spot volcanoes form?

  • when magma deep in mantle rises towards surface by convection

10
New cards

what do hot spot volcanic chains result from?

  • from plate motion over stationary plume

11
New cards

hot spot volcanic chain formation of Earth

  • crust, the magma extrudes through is quite dynamic

    • stationary source of magma under plate if moving

      • make way through curst to surface and firms a volcano

        • eventually, curst moves volcano off hot spout and lava stops erupting

          • still active and will create a new volcano
