An underwater scuba diver looks up toward the water's surface. she sees a buoy floating on the surface and notes its location. she then realizes that the buoy may actually be in a different location because she is looking at it from underwater. what is the wave property that best explains this phenomenon? absorption diffraction reflection refraction

Option D, Refraction

Explanation:

Refraction occurs when light passed from one medium to another with different reflective index.  

Here in this case as an object is seen from underwater, thus the light is going from a dense medium (water) to a lighter medium (air) thereby getting refracted at the interface of two different mediums. While moving from more dense to less dense medium, light gets refracted away from the normal.

Thus, option D is correct.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
