Plate tectonics

Tyler H 6th

1 What evidence did alfred wagner use to support his theory of continental drift

Continets they look like they can fit

2 Why do you think people didn't believe Alfred Wagner's theory

Because people thought it was crazy theory

3 Who were the 2 scientists that brought forth supporting to the theory of the continental

F.B. Taylor and Alfred Wagner

4 What are 3 plate boundaries

Divergent dividing convergent coliding transform sliding

5 What types of movement can occur between plates and what feature can form from this

Falls slides and flows

7 What do plate tectonics and ocean trenches have in common

Ocean ridges are produce

8How old are the rocks off the east coast of north America in relation to the rocks right along the mid atlantic ridge 9 why do you think this is the case

Plate tectonic and ocean trenches have in common the process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate called subduction.

10 What is a convection current and how does it work

a current in a fluid that results from convection.

12 What are 2 bad events that can happen as direct result of plate tectonics

Earthquakes and volcanos

13 How did plate tectonics cause these events

The Earth's ... Plate movement causes the buildup of tremendous quantities of energy in the rock

14What are 3 good things that plate tectonics provide for humans 15 how do plate tectonics cause these events

  1. Fertile soils-the physical breakdown and chemical weathering of volcanic rocks have formed some of the most fertile soils on Earth.
  2. Ore deposits-Rising magma does not always reach the surface to erupt; instead it may slowly cool and harden beneath the volcano to form a wide variety of crystalline rocks (generally called plutonic or granitic rocks).
  3. Fossil fuels-Heat and pressure at depth transform the decomposed organic material into tiny pockets of gas and liquid petroleum, which then migrate through the pore spaces and larger openings in the surrounding rocks and collect in reservoirs, generally within 5 km of the Earth's surface
