There are instances of low, rounded and subdued topographic features that sometimes being overlooked in the field and has not been seen or observed that's is why vertical exaggeration is necessary to enhance the measurement of height in models and presentation of terrains.
The tundra is a biome on the Earth that covers approximately 20% of its land mass, and it is almost exclusively located in the Northern Hemisphere. It is an environment that helps in the regulation of the CO2 in the atmosphere, and it is one of the biggest natural CO2 sinks. The living organisms in the tundra, are using the CO2 for their needs, thus removing parts of it from the atmosphere, and when they die, because the tundra is cold, and the decomposition is very slow, most of the CO2 remains trapped, and doesn't go into the atmosphere.
Unfortunately, the global warming is slowly changing the tundra, and prolongs the summer periods, thus reducing the permafrost period of the year, so the decomposition of the living organisms is getting quicker, and also bigger percentage of the CO2 from them gets to the atmosphere.
Answer:
To describe and summarize spatial data. To make generalizations concerning complex spatial patterns, to use samples of geographic data to infer characteristics for a larger set of geographic data (population).
Explanation:
Answer:
a) divergent boundaries by submarine eruptions and intrusions of basaltic magma
Explanation:
Divergent boundary is where tectonic plate move apart from each other. Divergent boundary is mostly prevalent in the oceanic crust. The opposing plate tends to move apart from each other.
On the oceanic crust plates move apart from each other causing an upwelling of magma from the aesthenosphere. This magmatic material is introduced through the oceanic ridges. As the magma are introduce the opposing plates separates further . The basaltic magma introduced through the oceanic ridges forms the new oceanic crust. As we move away from the oceanic ridge the rocks gets older . The oceanic ridge where the basaltic magma erupt depict the youngest rocks.
