provide evidence of how the contributions of scientists, as related to plate tectonics has had an impact on society
Semenov [28]

Answer:

  • Earthquakes
  • Tsunamis
  • Volcanoes

Explanation:

An understanding of plate tectonics has saved many lives. The benefits of understanding how the Earth moves underneath our feet are enormous. Before the theory of plate tectonics, no one knew why Earthquakes occurred, why volcanoes erupted how and where they did, or why giant waves destroyed entire coastal areas or islands out of nowhere.

With the theory of plate tectonics we not only understand the orientation of the continents millions of years ago, but we also can plan cities intelligently to avoid seismically active areas. We can also predict when a tsunami will occur and gauge the potential devastation of a volcanic eruption before it happens.

Explain what drives the continental and oceanic plates. Include
Marianna [84]

Answer:

Earthquakes and volcanoes.

Explanation:

Earthquakes and volcanoes are responsible for the movement of these continental and oceanic plates because movement of these tectonic plates occurs due to convection currents in the molten rock in Earth's mantle present below the crust. Earthquakes and volcanoes are the short-term results of these tectonic movement while the long-term result of these tectonics causes the movement of entire continents over millions of years. The density of crust is 2.2 g/cm3, the density of upper mantle is 3.4 g/cm3, the density of lower mantle is 4.4 g/cm3, the density of outer core is 9.9 g/cm3 and the density of inner core is 12.8 g/cm3

If x = 9 units, y = 3 units, and h = 11 units, find the area
Volgvan

Answer:

297 units^2

Explanation:

Let's keep the area or volume as 'v'

v = x \times y \times h

So if we substitute in the values we get,

v = 9 \times 3 \times 11

v = 297

So therefore, the total volume is 297 units^2
