The theory of continental drift by Alfred Wegener states that all land masses were originally united
in a single supercontinent known as Pangaea (250 million years ago). He shows
evidences like continental fit, similarity of rock sequences, glacial till and
striations, fossils (cynogathus-land reptile, lystrosaurus-land reptile,
mesosaraus-freshwater reptile, glossopteris-fern plant) to support his theory but
what was lacking is that it lacked a mechanism to explain HOW the continents
moved apart. But Harry Hess, a geologist and Navy submarine commander during
WWII <span>brought up a new
evidence to add in support of Wegener’s theory: the idea of seafloor spreading and magnetic reversals.</span>
Answer:
New Orleans, LA (2 m below sea level)
Explanation:
In this examples, we can see that the places with the highest altitude (meters above sea level) are also the places with the lowest atmospheric pressure. Therefore, we can conclude that the opposite is true too. The places with the lowest altitude are the ones with the highest atmospheric pressure. The place with the lowest altitude is New Orleans, as it is located 2 m below sea level.
A dune<span> is a mound of </span>sand<span> formed by the wind, usually along the beach or in a desert. </span>Dunes form<span> when wind blows </span>sand<span> into a sheltered area behind an obstacle. </span>Dunes<span> grow as grains of </span>sand accumulate. Sand dunes<span> serve an important purpose by protecting inland areas from coastal water intrusion. They are able to absorb the impact and protect inland areas from high energy storms and act as a resilient barrier to the destructive forces of wind and waves.</span>
Answer:
D. It completely removes any available topsoil.
Explanation:
Open pit mining strips off the top layer of the soil in order to access near surface mineral deposits. Most near surface deposits are usually rock aggregates, coal, copper etc.
In order, to access these minerals, large amount of earth must be removed by earth moving machines.
Open pit mining greatly unsettles the ecosystem in mining regions and it leaves the surface bare and not suitable for agricultural activities.
