The study of the history of earths magnetic field is known as

Answers

Answer 1

Answer: Paleomagnetism is the science of studying the magnetic properties of rocks, sediments, and artifacts which developed in the rocks due to the power and orientation of the earth’s magnetic field while the rocks, sediments and artifacts were being formed. By studying the rocks and sediments scientists can determine when the history of earth’s magnetic field reversed.

Answer 2

Answer:

Answer:

Paleomagnetism is the study of the history of earths magnetic field in ancient rocks and minerals.

Explanation:

This concept was revealed by the French physicist Achilles Delesse in 1849, who detected that certain magnetic minerals in rocks were associated parallel to Earth’s magnetic field. The study of paleomagnetism started in the 1940s when the British physicist Patrick M.S. Blackett designed a device for calculating the magnetic fields linked with magnetic minerals.

Nowadays, two more devices are used to study paleomagnetic materials: the spinner magnetometer and the cryogenic magnetometer. Each of these devices signifies a noteworthy development in the aptitude of a researcher to perceive and measure the magnetic field linked with a mineral.

What state is at 20 degrees north and 157 degrees west

Answers

The continental US goes until about 125 Degrees west: the rest of the states are more to the East, for example, Masschusets is between 70 and 75 degrees West.

More to the west are only Alaska and Hawaii, but Alaska is much more to the north.

So the correct answer is: Hawaii!

Well, the water is 65 km and its 40 miles from land, and Hawaii is near water and 40 miles from land, so the correct answer would be Hawaii.

Which of the following are you more likely to have in temperate rainforests rather than tropical rainforests?a. insects
b. high annual rainfall
c. pine cones
d. limited ground vegetation

Answers

The correct answer is - c. pine cones.

The pine cones are a product of the pine trees, and these types of trees can only be found in more temperate and cold climates. The pine trees are highly evolved to long, snowy, harsh, cold winters, and that is because the places where they live (in the mid-latitudes) tend to have long and harsh winters.

On the other hand, a pine cone will not be found in the tropical rainforests simply because they are too hot and too humid for this type of highly specialized trees, so they would die out in that environment very quickly.

Tropical rainforest is distinguished by limited ground vegetation and temperate rainforest - not as much.

High annual rainfall can be found in both.
The correct answer is that pine cones would rather only be found in the the temperate rainforest - the answer is c)
