  • is 1000-1100C
  • could have been Pahoehoe
  • is felsic
  • is more liquid

Questão 26

Questão
when decompression occurs
Responda
  • there is reduced pressure, which allows the atoms to vibrate more
  • it is at divergent plate boundaries
  • the decrease in pressure causes the lava to fill the now empty space
  • if the magma moves up fast it can melt as it there is less and less pressure keeping the atoms confined
  • it produces large amounts of new lithosphere
  • it is generally mafic magma which then creates basalt

Questão 27

Questão
when hydration melting occurs
Responda
  • it is at convergent plate boundaries

  • False

Questão 40

Questão
when the field strength reaches zero
Responda
  • there can be a polar reversal
  • things can stay the same
  • organisms are introduced to more radiation

Questão 41

Questão
centrifugal force keeps the international space station orbiting the earth by counteracting the normal force
Responda
  • True
  • False

Questão 42

Questão
gravity in the center of the earth is only dependent on the stuff directly beneath you because
Responda
  • there is more beneath you, but it's cancelled out by what's above
  • there's more mass above, but the mass below is heavier and cancels it out
  • the mass above is pulling up, which is cancelled out by the mass farther below, pulling down

Questão 43

Questão
apparent gravity is
Responda
  • the gravity that can be observed
  • the gravity at any point on earth

Questão 44

Questão
gravity is weaker by 0.05 at the equator because
Responda
  • the heat interferes with gravitational field lines
  • earth's oblong shape causes more centrifugal force to be at the equator, counteracting gravity to a small degree
  • there is more mass between earth's core and equator

Questão 45

Questão
isostasy means
Responda
  • the weight of the mountains is equal to the weight of the displaced mantle
  • that whatever is closest to earth's core will feel more gravity
  • that the more dense mountain condenses the mantle

Questão 46

Questão
depth at which mantle flow occurs is the
Responda
  • compensation depth
  • moho
  • focus depth

Questão 47

Questão
elevation is dependent on
Responda
