Answer:
Higher elevations experience cooler temperatures compared to lower elevations.
Explanation:
Elevation helps to determine the temperature of an area through relationship between availability of air and the pressure. The higher the elevation, the lower the availability of air which in turns leads to lower pressure.
This lower pressure influences the temperature of that point to be cooler. At same time, the lower the elevation and all things being equal, the hotter the temperature.
Venus: almost no surface winds, sulfuric acid clouds, runaway greenhouse effect.
Earth: atmosphere composed primarily of nitrogen and ultraviolet-absorbing stratosphere
Mars: extremely low-density atmosphere, global dust storms.
Answer:
Afghanistan's mountains have kept the country from ever being invaded.
Explanation:
Afghanistan is a country in terrible conditions, and this is not the case just nowadays but it has been like that for a very long time. Despite all of the internal troubles of the country and it seems to be very weak in pretty much every sector, it has never been invaded in the past few centuries, and very rarely in the more distant history and always it has been short-lasting.
The main reason for this has been the mountains and the general geography of the country. Very high and rugged mountains are separating the country from potential invaders. Even if an invading force manages to go through the mountains, it will suffer great losses just by doing so, and what comes next is desert and more rugged terrain, which will further damage them, so by the time they engage in battle, they will be too weak to conquer Afghanistan.
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:
potassium-argon dating
Explanation:
Potassium-argon (K-Ar) dating technique is the most appropriate dating method for establishing the age of a volcanic ash. It is most applicable for dating minerals and rocks more than 100,000 years old. It is based on measuring the product of the radioactive decay of an isotope of potassium (k) into argon (Ar). Since potassium is a common element found in many volcanic ash layer, the time since re-crystallization is calculated by measuring the ratio of the amount of argon 40 (Ar-40) accumulated to the amount of potassium 40 (K-40) remaining in these volcanic ashes.
