Oceanic Crust
Continental Crust
Oceanic crust is denser than continental, this is why continents are at higher elevation than oceans.
I'm assuming you meant subsistence farming? If so then yes, it would be a large problem because they would then not have enough food to feed themselves.
Answer:
Oceans heat up and cool down much more slowly than land. This means that coastal locations tend to be cooler in summer and warmer in winter than places inland at the same latitude and altitude.
Explanation:
Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.
Answer:
March equinox is day during the year when all the daylight of the sun is asme at sunrise and sunset.
Explanation:
- Equinox is the time when the plane of the earth passes through the centre of the sun. Occurring around 23 March and 23 Sept. The vernal equinox is also called as the spring equinox.
- The azimuth of the sun is the angle of the sun's position defined by the relative direction along the horizon. However the most commonly followed convection for analyzing the sun radiation is 90 degrees east, south 180 degrees and west is 270 degrees.
- As sunrise and sunset are defined by the upper limb of the solar disk. These conditions produce patterns of night and day as the sun appears to move just above the horizon at an angle of 0.39 degrees per day as the equinox passes.
