How does the observed pattern of magnetic reversals support the theory of sea-floor
spreading?

Answers

Answer 1

Answer:

When the Earth's magnetic field reverses, a new stripe, with the new polarity, begins. Such magnetic patterns led to recognition of the occurrence of sea-floor spreading, and they remain some of the strongest evidence for the theory of plate tectonics.

What is sea-floor spreading ?

Seafloor spreading is mainly caused by tectonic activity that is constantly occurring within the tectonic plates of the Earth.

Tectonic plates are moving because they are situated on the crust of the Earth, which lies on top of a partially molten layer of rock, called the asthenosphere.

Tectonic plate movement is responsible for the formation of natural landmarks such as mountains and volcanoes, and natural disasters such as earthquakes.

explain how precipitation affects the phosphorus cycle

Answers

Answer:

Disrupts the nitrogen cycle by contaminating the groundwater and making it more difficult for the plants to absorb the nitrogen and causes the phosphorus cycle to accelerate, resulting in an excess of phosphorus in water and soil.

Explanation:

The precipitation affects the phosphorus cycle in many ways where the soil erosion will take place if the precipitation happens then the weathering of rocks along with the soil getting off will make the nutrients loss in the soil.

What is the cycle of rain called as ?

The cycle of the rain is  called as water cycle where the evaporation along with the condensation takes place.

If the precipitation level in the atmosphere is increased then in this case it will increase the transportation of phosphorus along with the other nutrients into soil along with the water sources and the coastal areas as well.

The main reasons of such scenario is because of the deforestation, loss of habitat by the continued invasion of human activities in the natural resources. The reduction of nutrients loss in  soil makes an huge impact over the  phosphorus cycle.

How is an occluded front different from a cold front?
a) Warm air is pushed up during an occluded front, while cold air moves quickly during a cold front.
b) Occluded fronts cause warm air to feel dry, while cold fronts cause ground temperatures to feel cooler.
c) Warm air moves slowly during an occluded front, while cold air is cut off from the ground in a cold front.
d) Occluded fronts cause rapid changes in weather conditions, while cold fronts cause widespread cloud formation.

Answers

Answer:

A cold front forms at the leading edge of the colder air mass the cold front can bring thunderstorm in the region whereas the occluded front can bring strong winds and precipitation. so its probably d

Occluded fronts cause rapid changes in weather conditions, while cold fronts cause widespread cloud formation. Therefore, option (D) is correct.

What are occluded fronts?

Because of their different densities, large masses of warm air and cold air do not mix when they come into contact with one another. They instead organize themselves into a front that is typically hundreds of miles long. When a warm air mass is sandwiched in between two cold air masses, the result is a phenomenon known as an occluded front. The mass of warm air rises as the masses of cool air push against one another and meet in the middle. The warm air mass is occluded, which literally means "cut off," from the ground, and pushed upward, which causes the temperature to drop. These types of fronts are known to bring blustery winds and significant precipitation.

Occluded fronts typically develop near low pressure areas that have reached their mature state.
