Answer:
b less dense and thicker under the continents than under the oceans
Explanation:
- <em>Oceanic crust </em>is found under the ocean, it's about 6 kilometers thick and is destroyed in subduction zones just like the continental crust. It's composed of several layers and it differs from continental crust because it's thinner, denser, younger and with a different chemical composition (olivine, pyroxene, and amphibole).
- <em>Continental crust</em> is thicker (100 kilometers) and less dense than oceanic crust, it resists subduction and its age is 30 times the average of the ocean's age.
Considering this information we can conclude that the correct asnwer is: b less dense and thicker under the continents than under the oceans.

Answer:
It takes much longer to heat and cool the oceans than the continents.
Explanation:
The Southern Hemisphere and Northern Hemisphere, despite being equal in size and receiving the same amount of sunlight, have big differences in climate. This is the case because the Northern Hemisphere has much more landmass, while the Southern Hemisphere has much more ocean water.
The land is changing temperature much faster because it can heat and cool off very quickly, thus the temperature variations are very large, not just from season to season, but also between day and night. The water, on the other hand, is heating up and cooling off much slower, so its temperature is never oscillating a lot. This results in much smaller temperature swings, so the climate tends to be much milder than the climate in the Northern Hemisphere.
Answer:
A triangulation station, also known as a triangulation pillar, trigonometrical station, trigonometrical point, trig station, trig beacon, or trig point, and sometimes informally as a trig, is a fixed surveying station, used in geodetic surveying and other surveying projects in its vicinity.
