Answer:
mantle convection, ridge push, and slab pull
A and b bid population=lot of devastation:)
Answer:
c. has been determined by radiometric dating
Explanation:
- Radiometric dating is a method that is used to determined by the age of rocks as per the age of the oceanic crust the plates near the mid oceanic ridges are the most recent or new.
- The plates that are located farther away form there ridges are oldest and hence the age of the oceanic crust is not the same in all the places of the world oceans.
Answer:
Atmospheric Pressure and Winds belts.
Explanation:
- As the fluid is heated it rises as the molecules get energy on heating, similarly the particles cool when they are condensers at a certain temperature that causes them to sink a similar pattern is found in the atmosphere also. The light arises and heavier air falls as it's dense and hence sinks again.
- Similarly, the earth heating patterns that are derived from convection currents coming from the mantel are also derived from the tectonic processes from within the earth's interior.
- Within the atmosphere and oceans are also found the wind and pressure belts that rotate in the spherical motion and derive up and down from the equator of the earth. The poleward cool air and hot air from the equator are mixed and create turbulence in the upper atmosphere in the form of Jet steams and westerlies and easterlies that derive the weather patterns around the globe.
Answer:
<em>Captain James Cook’s first exploration was to Tahiti to observe the transit of Venus in 1969.
</em>
Explanation:
James Cook was born in Yorkshire in 1728 to a farm labourer. He sailed for several years in the North Sea, Irish Sea, Baltic Sea. He volunteered many services with which he as appointed as an able seaman. He also worked as rank master, surveyor.
In 1969, he was promoted as a rank of Lieutenant and was instructed to sail to Tahiti to observe the transit of Venus in 1969. This expedition was to ascertain whether there is an existence in the Southern latitudes of the Pacific Ocean.
