where is earth's magnetic north pole?​

Answers

Answer:

The north magnetic pole is a point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down)

Explanation:

There is only one location where this occurs, near (but distinct from) the geographic north pole. The geomagnetic north pole, a related point, is the pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's actual magnetic field.

The Earth's magnetic pole is situated at west of the Ellesmere Island in northern Canada at the geographical location of 81°18′N 110°48′W.

What is the Earth's magnetic pole?

The generation of the Earth's magnetic field occurs deep within the Earth's interior, in a layer which is known as the outer core to be more precise. Here, the convective energy from the slow-moving molten iron is converted to the electrical and magnetic energies.

The north magnetic pole of the Earth moves over time according to the magnetic changes and flux lobe elongation in the Earth's outer core. In the year 2001, it was determined by the Geological Survey of Canada to lie west of the Ellesmere Island in northern Canada at the geographical location of 81°18′N 110°48′W. It was situated at 83°06′N 117°48′W in 2005.

Fraternal twins, while conceived at the same time, are not genetically identical.

Which statement best explains why these siblings are genetically different from each other

Answers

Answer:

Fraternal twins are also called dizygotic twins. And the difference between fraternal and identical twins is that fraternal twins derive from two different eggs. Fraternal twins may be the same gender, they may have many of the same characteristics, but also may be very different from each other and, in fact, share half of their genes just like their sisters and brothers. It's important to recognize that the difference between fraternal twins and monozygotic, or identical twins, is that monozygotic twins result from the fertilization of a single egg with a single sperm and then during the embryonic development, or during the cell splits, those massive eggs split into two individuals, which later develop into two offspring.

A drought is a long period of abnormally low precipitation. Suppose a drought occurred in Yellowstone National Park from 1916 to 1917. Predict how a graph line would appear for this time period. Explain your prediction in terms of the effect on resource availability.

Answers

Answer:

A drought is a long period of abnormally low precipitation. Suppose a drought occurred in Yellowstone National Park from 1916 to 1917. Predict how a graph line would appear for this time period. Explain your prediction in terms of the effect on resource availability.

Explanation: The graph line would have a downward trend because the amount of bison would start to decrease. Droughts heavily impact grassland ecosystems. A drought would increase the risk of a wildfire starting causing the bison to lose their habitat. The drought would also result in reduced plant growth. Therefore the bison would die off either because they were impacted by a wildfire, because they don’t have grass to eat etc.
