In geography, the core, mantle and crust of a planet are defined by differences in their density.
How Many Layers does Earth Have?When we are referring to the rocky portion of the Earth, there are three layers of the Earth. However, the planetary rock called the Earth does not just consist of the rocky layers which is where the complexity arises.
The Earth's layer's names are as follows:
The Crust: Which is the outer layer of rock on which humans and animals live and plants grow.The Mantle: Which is a semi-solid magma layer consisting of iron, magnesium, and silicon.The Core: Which is centrally located solid mass of metal (inner core) and a liquid mass of iron and nickel (outer core).As well as individual layers of each of the three layers of the rocky Earth, the Earth plant consists of many layers of the atmosphere, the gaseous bubble surrounding the planet. That is, out Earth's atmosphere is made up of five layers that extend 10 miles out from the surface of the planet.

Storms that move northward along the eastern shore of north America during winter may produce heavy snowfalls by combining cold arctic air with warm, moist air coming in from the ocean. These storms are known as nor Easters.
Nor Easters are formed in North America when a cold air front and warm air front coincide with each other over the ocean forming a low-pressure system.
In this low-pressure area, clouds are produced that are gradually developed into a storm-like condition leading to nor Easters storms that move along the eastern shore in a northward direction during the cold weather season.
For example, a cold front originates from Canada and slides over the Atlantic ocean off to the eastward shore of the United States resulting in nor Easter storms.

One way to treat a dying beach is to dig up sand somewhere and dump it on the beach. What is this likely to accomplish?.
One way to treat a dying beach is to dig up sand somewhere and dump it on the beach. The extra sand is cleaned back to water depths by waves and currents, causing the beach to lose the fresh sand over the next year or so.
Waves and currents move a lot of sand. To make up for this, we'll have to move a lot of sand. Constructing beaches from mining process sand can work, but the sand quickly returns to deep water, so the activity must usually be replicated every year or after a few years to keep the beaches large and sandy.

Will marine food sources keep up with human population growth?
Answer:
That is a 50/50 chance of happening.
Explanation:
Why?
The human population is projected to reach 9200 million by 2050 (UN 2007), which is within estimates of the maximum carrying capacity of the planet (Cohen 1995). A fundamental question for science is whether it is possible to increase food production to meet the demands of a human population of that magnitude.

the average temperature on planet earth is higher than you would expect just from the heating of sunlight alone. what is the main explanation for this?
The average temperature on planet earth is higher than you would expect just from the heating of sunlight alone as Carbon dioxide (and other gases) in the atmosphere cause a greenhouse effect.
When gases in Earth's atmosphere capture the heat from the Sun, the process is known as the greenhouse effect. Earth becomes significantly warmer as a result of this process than it would be without it. One of the factors that makes Earth a desirable place to live is the greenhouse effect.Without greenhouse gases, Earth would be below freezing, but the planet's natural greenhouse effect prevents this from happening. Additionally, when greenhouse gas concentrations rise due to human activity, more heat is trapped and the Earth gradually gets warmer.

Theory that continental plates are floating a too molten magma causing them to slowly move around from a super continent into the location that they are currently in
Plate tectonics is the theory that the land masses on Earth are constantly moving. Alfred Wegener proposed the concept of continental drift, or the movement of Earth's land masses.
Plate tectonics theory revolutionized earth science by describing how the movement of geologic plates creates mountain formation, volcanoes, and earthquakes. Plate tectonics theory proposes that the Earth's outer shell (lithosphere) is split into many plates that glide over the rocky inner layer just above soft core (mantle). In comparison to the Earth's mantle, the plates act as a rigid and hard shell.
