Theory of Continental Drift

If you take a look at a map of the earth today, you will see the current locations of broken land masses that constitute the earth. However, would you believe if someone told you that these broken land masses were once connected to each other as one huge supercontinent?  Well, this claim was made in the 90’s by Alfred Wegener, a German polar researcher, meteorologist and geophysicist who died in 1930.

Wegener’s theory of continental drift states that the existing continents of the earth were once glued together forming a super landmass. Over time, the landmass broke and drifted away and is still drifting to this day. In his proposal, he stated that the super content, which he named Pangaea, meaning ‘’all earth” once existed. The supercontinent was surrounded by water bodies, mainly oceans, and seas.

Answer:

Mountain ranges provide evidence because they are separated by bodies of water on different continents. If the pangeia existed, these mountain ranges would be equal because the continents would be placed next to each other.

Explanation:

The main evidence of the theory of continental drift - and which made it possible to prove it after the Second World War - was the existence of ocean ridges, which are submarine mountain ranges originated by the expulsion of magma through geological cracks, located at points of separation between two tectonic plates.

These mountain ranges provide evidence because they are separated by bodies of water on different continents. If the pangeia existed, these mountain ranges would be equal because the continents would be placed next to each other.

A confined aquifer has a specific storage of 2.4 x 10-S ft and a thickness of 300 ft. How much water (in acre-ft) would it yield
Georgia [21]

Answer:

water it yield is 244290.45 ft

Explanation:

given data

specific storage SS = 2.4 × 10^{-5} ft

thickness b = 300 ft

water declined ΔH  = 4.8 ft

radius r = 1,500 ft

to find out

How much water  would it yield

solution

we know that

volume of water is

Vw = S × Area ×  ΔH    ..............1

here S = specific storage × thickness

S = 2.4 × 10^{-5} × 300

S = 7.2 ×  10^{-3}

and

area = πr² = π 1,500² = 7068589.471 ft²

so

volume of water is

Vw = 7.2 ×  10^{-3}  × 7068589.471 ×  4.8

Vw = 244290.45

so water it yield is 244290.45 ft

Which of the following plate boundaries and hot spots have volcanic activity (magma generated)?
ddd [48]

Answer: Options (1), (3), (4), (6) and (9)

Explanation: Hot-spots are the region of active volcanisms and this could be due to the presence of large mantle plumes, plate tectonic movement, as well as other reasons.

Hot-spots are generated in the following tectonically active boundaries such as-

  • Convergence of two oceanic plates.
  • Convergence of an oceanic and  continental plate.
  • Divergence of two oceanic plates.
  • Hotspots within the oceanic and continental plate.

What motivates civilizations to take risks by exploring and colonizing new territories? Describe two motivations for colonizatio
expeople1 [14]

Answer:

Usually famine causes angst between the weakened civilation so the owners of said territories usually hunt for more fertile land so they can sustain their growing population without having being thrown out of power and slain, its often better to satisfy the people who you govern rather than to exterminate to govern the population steadily.

and to own more land is more money and more power for such rulers, if they own more land they can tax more people, and if they own fertile land they can grow crops to sustain themselves, and the people they govern, satisfying the ruler AND the people.
