Answer:
convergent boundaries
Explanation:
About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on
Answer:
Air rises at the equator, leading to low pressure and rainfall. Global atmospheric circulation creates winds across the planet and leads to areas of high rainfall, like the tropical rainforests, and areas of dry air, like deserts. And for the hazards, Physical removal of the hazard is the most effective hazard control. For example, if employees must work high above the ground, the hazard can be eliminated by moving the piece they are working on to ground level to eliminate the need to work at heights.
Explanation:
Answer:
1 : 25,000 is the largest scale.
Explanation:
1 cm represents 2 km; is not correct because this is actually the smallest of the scales presented, meaning that 1 cm on the map is equal to 200,000 cm on the ground.
1 : 50,000; is not correct because this is the second-largest scale from the options.
1 : 25,000; is correct because it is the largest scale, with 1 cm on the map representing 25,000 cm on the ground. The smaller the scale, the larger it is.
1 : 100,000; is not correct because it is the third-largest, with 1 cm on the map representing 100,000 cm on the ground.
Answer: D) Mexico city is in Central America
Explanation:
Reason being that Mexico is part of the North American region with Canada and the United states. The central american countries are all those that border below mexico between mexico and Colombia. Hoped this helped.
Answer:
This is the best explanation for why there is such a small amount of phosphorus that moves into aquatic systems:
1. Phosphorus is highly stable in the atmosphere and remains there for long periods of time.
Explanation:
The phosphorus first cycle is the process by which the phosphate ion passes in very small amounts through the lithosphere from volcanic aeorosols, then to the hydrosphere, where it stays from 20,000 to 100,000 years in the ocean, and finally to biospherere, where rain and erosion helps washing the phosphorus from the rocks into the soil. So, raining is the beginning of the phosphorus´s second cycle, so it is also, the slowest one of the matter cycles that is why the natural total background phosphate levels in several bodies of freshwater range from 0.005 to 0.05 mg/L. Phosphorus remains mostly on land and in rock and soil minerals.
Although abundant on our planet´s sedimentary rock crust and in human body, phosphorus to commercialize is only found in minerals therefore, phosphates mining activity and calcium heating is the only way to get it in its pure elemental form. It is an essential nutrient for plants and animals and a big percentage of the mined phosphorus is used to make fertilizers.
