Fenómenos naturales es a veces una tragedia, pero a veces para ayudar a nuestro planeta. Lluvia, nieve y granizo se encuentran entre algunos de ellos. Los tres fenómenos producen agua y puede ser grave, pero por eso siempre debemos ser prudentes. El calentamiento global está aumentando y está consumiendo el hábito natural de la Antártida. Esto también provoca poner en peligro a la criatura.

Si la lluvia se intensifica puede tener efectos positivos como el riego de zonas de cultivo, y efectos negativos como las crecientes de los ríos que desencadenan desastres naturales. También su ausencia puede causar efectos negativos como escasez de agua.

Fenómeno natural es un concepto que se refiere a distintas manifestaciones de la naturaleza que se caracterizan por no ser provocadas por acción humana tales como:

Los fenómenos naturales pueden tener efectos negativos, positivos y neutros sobre las comunidades humanas. Por lo anterior, si las lluvias se intensifican podrían causar efectos positivos como riego de zonas de cultivo. No obstante, también puede tener efectos negativos como crecientes de ríos que desencadenen desastres naturales.

Por otra parte, la ausencia de lluvia puede causar efectos negativos dado que limitaría el acceso al recurso del agua, lo que podría afectar la vida vegetal y animal.

The phreatic zone

Explanation:

The phreatic zone is the zone is the part of an aquifer that is present below the water table, where all pores and cracks are saturated with water. The above layer of the water table is the vadose zone. The size, color, and depth of phreatic zone may change with changes of season as well as wet and dry periods. It is also called zone of saturation due to complete filling of pores.

Answer: This statement is clearly false. The HST observes visible and infrared light, not gravitational waves.

Explanation:

Gravitational waves refers to ripples in spacetime. The statement that gravitational waves are best observed with the Hubble Space Telescope is false.

This is because the Hubble Space Telescope is used in observing visible and infrared light, not gravitational waves. The telescope has helped scientists to understand how the planets are formed.

Answer:

The answer is "Provide strong evidence for seafloor spreading".

Explanation:

The magnetic changes from east to west and vice versa are geomagnetic. geomagnetic reversals. And they can provide significant evidence of the expansion of sea bed in the rocks formed along the middle sea ridges by documenting the geomagnetic pattern of echo.

A new crust is developing from the magma explosion into the seafloor in the ocean along the mid-oceanic ridges along the mid-ocean ridges. When the magma cools, the minerals of ferromagnetism found in the magma will align as per the magnetosphere of this time.

In the event of geomagnetical revolutions, newly formed minerals will be reverse-aligned to early elements, thus registering the lithosphere on both sides of the mid-oceanic ridge. Lithosphere, one could argue, is a continual move away from oceanic crusts midway through.

Answer:

Humans using water to generate electricity does not negatively affect groundwater.

Explanation:

Rainwater, which is mostly fresh, drains into sewers most of the time of course. They are abundant in many towns, cities, etc. As a result, rainwater is not utilized enough, as it goes to waste when blending in with dirty sewer water. This leads to rainwater not draining into aquifers, And with the worlds population increased rapidly by the minute, consumption increases, leading to the water contained within aquifers to decrease in amount. Runoff from things such as pesticides and fertilizers is also a major issue that harms groundwater. As rain approaches, these chemicals can seep through dirt and soil, eventually going as far as to reach the groundwater underneath the surface, contaminating it. And humans utilizing water to generate electricity is more of a benefit to the environment. It is another effective way to get power, and is an alternative to fossil fuels. And using groundwater as a power source does not really affect the groundwater itself, so this is why the last option is correct.

Answer:

Explanation:

The water depth in the surf zone is between 5 to 10 meters deep and with a wavelength of 30 meters, the speed of the wave is considerably fast such that control for safety may be difficult

Also the speed of the wave is directly related to the depth of the water which means that where the wave described above is fast as well as the rip current, also the water depth is expected to be considerable for a non swimmer

It is best to seek for sign post regarding safe areas and do not go into the water where there are no lifeguards or marked safe zones.

Answer:

The answer D

Out of the total water resources available, the agricultural sector uses 52%; whereas the rest of the water is used by industries and households.

The natural resources that provide water for consumption and other uses, are known as the water resources. For example, lakes, rivers, ponds, glaciers are some water resources.

Only 3% of the total water resources are fresh and suitable for human consumption. More than half of the total freshwater is used for agricultural activities, and about a quarter each by the industries and the households.

Hence, option D holds true of the consumption of the available water resources.

The map shows the locations of 13 major river basins in Africa: the Senegal, Volta, Niger, Lake Chad, Nile, Lake Turkana, Juba Shibeli, Ogooue, Congo, Zambezi, Okavango, Limpopo and Orange river basins. This spectacular Southern African waterfall, considered to be among the greatest in the world, is located along the Zambezi River and straddles the border between Zambia and Zimbabwe. The awe-inspiring nature of the waterfall is in part due to its enormous width—more than 5,500 feet (1,700 meters). The waters plunge as far as some 355 feet (108 meters) down and drop not into an open basin but into a dramatic-looking chasm. Victoria Falls is known for its veil of mist visible from miles away; the name given to the falls by an indigenous group is Mosi-oa-Tunya (“The Smoke That Thunders”). Victoria Falls and the adjoining areas were collectively designated a World Heritage site in 1989.
