How does paleomagnetism provide support for the idea of sea floor spreading?
Rocks that are found at on the sea floor of the Earth differ in magnetizations. Using paleomagnetism, these rocks were known to have preserved an imprint of the changes in the earths magnetism over long periods of geological time, which proved the theory of sea floor spreading.
What would happen to animals if the amount of oxygen the earths atmosphere decreased?
youll die
What two elements make up more than 80 percent of the atoms found in the earths crust?
Oxygen and silicon make up more than 80 percent of the atoms found in the Earth's crust. Oxygen is the most abundant element in the Earth's crust, comprising about 46.6% of the crust by weight, while silicon is the second most abundant at around 27.7%.
What conditions allowed so many different kinds of mammals to evolve during the Cenozoic era?
Earth's climate warned during the tertiary period which allowed marine life to evolve and grasses evolved as well which meant grass eating mammals had a food source. Then the earths climate cooled facing a series of ice ages. Then 20000 years ago earths climate warmed again so ocean animals and land animals thrived.
What did the earths surface look like in the Cambrian time?
During the Cambrian period, around 500 million years ago, the Earth's surface looked vastly different from today. The supercontinent of Gondwana covered much of the southern hemisphere, while ocean basins were expanding. The land was mostly barren, with simple plants and algae beginning to emerge.
What are devices that work because of earths magnetism?
Electromagents
Does the Earths magnetism cause the Earth to orbit the sun?
No. Magnetism has nothing to do with it. It's strictly the result of gravity.
What is a geological event that is not dangours?
The reverse of the earths magnetism is not dangerous to humans as we do not rely on magnetism to guide us anymore. It will cause mass extinction of birds though.
Is earth's magnetism related to the circulation of molten material within Earths core?
TRUE (this is the correct answer)
How is the orientation of earths magnetism recorded in rocks on the?
Earth's magnetic orientation is locked into the rock when the rock cools
How do birds learn how to migrate?
Its an internal instinct, and some scientists say it has something to do with the Earths magnetic pull.
Where in the interior of earth do geologists believe that the earths magnetism is influenced?
Convection of liquid metals in the outer core creates the Earth's magnetic field.
What is a danger to humans if the ozone layer is destroyed?
we die because of the solar radiation, right now the ozone and the earths magnetism protects us
Is there a connection between the earths tilt and the tropics of Capricorn and Cancer?
Yes, the Earth's tilt is responsible for the existence of the Tropics of Cancer and Capricorn. These lines mark the farthest points north and south where the sun appears directly overhead at least once a year, which is influenced by the tilt of the Earth's axis in relation to its orbit around the sun.
what device that works because of the earths magnestism?
A compass relies on Earth's magnetism to stay pointed north.
Why are the tropics the earths warmest regions?
They receive more direct sunlight than the other parts of the globe.
How do scientists know that earths gravity and magnetism can work through gases solids and liquids?
Scientists know that Earth's gravity and magnetism can work through gases, solids, and liquids because they have observed these effects in various materials and environments. They have conducted experiments and studies to understand the behavior of gravity and magnetism in different mediums and have found consistent results. Additionally, theoretical models and mathematical equations have been developed to explain how gravity and magnetism can act through different states of matter.
