Describe how plant fossils found at Svalbard in Norway gave evidence of drifting continents.

They were found only in that one location.

They were found in glacial deposits.

They were warm climate plants that would not grow in a cold polar area.

They were plants that became extinct millions of years earlier.


How were the Himalayas formed?


when two plates collided with each other

due to a sudden shift along a transform boundary

due to an increase in volcanic activity

when a mid-ocean ridge split apart






Identify the type of plate boundary that created the volcanoes of Iceland.

a transverse boundary on land

a divergent boundary in the ocean

a convergent boundary on land

Respuesta :

Answer:

1. They were warm climate plants that would not grow in a cold polar area., 2. when two plates collided with each other, 3. a divergent boundary in the ocean, 4. type of lava, height, steepness. 5. the magnetic direction of rocks along the surface of Earth, the age of rocks along the surface of Earth.

Explanation:

  • As Svalbard lies along the arctic circles i.e midway between Norway and the north pole. Having a flat and relatively and undulating terrain with lake legumes and alluvial fans and seems to contain coal with plant fossils that were original of the Carboniferous period later on it was subjected to warm and humid temperature and thus the presence of sedimentary rocks was to found preserve the fossil remains. After which it was subjected to two of three glaciations.
  • The Himalayan orogeny was caused by the closing of the Tethys sea by the presence of the Indian subcontinent.
  • Icelandic volcanoes are created by the divergent boundary of plates that run form oceans and thus this region is prone to earthquakes and volcanic eruptions.
  • For classifying a volcano we need to look at the age of rocks, steepness height of the volcano along the lava type.
