What physical law describes the manner in which the intensity of sunlight changes as the observer moves away from the sun?
The Conservation of Energy or power Law. This gives the inverse distance law of Intensity: Intensity on Earth = intensity on sun (radius/sun distance to earth)2 .
What phenomenon is sometimes reffered to as the nortern lights?
Aurora Borealis or the Northern Lights occur when solar activity ejects a cloud of gas. When the cloud of gas hits Earth's magnetic field, it causes complex changes to the magnetic field, These changes generate currents of charged particles, which then flow along lines of magnetic force into the Polar Regions. These particles are boosted in energy in Earth's upper atmosphere, and when they collide with oxygen and nitrogen atoms, they produce dazzling auroral light.
Why does the sun change colour?
In reality, the sun is white. It appears to be different colors because of the way sunlight reflects off the atmosphere. The sun never changes color.
Why would magnetic declaration be different for different locations on the earth?
First of all, we're pretty sure that you're referring to "variation", not "declaration".Magnetic variation is the difference between the direction from you to the north pole (called "true north"), and the direction in which your magnetic compass points.That difference changes with your position on earth, because the north pole and theplace your compass points to are two different places. If you were standing at the point that's exactly halfway between them, then your compass would point exactly away from the north pole. And if you're not between them, but you're standing on the extension of the line between them, then your compass it pointing at the north pole, because both points are in the same direction from you.If you look at a navigational map, you will see lines of magnetic variation printed on the map. If you read your magnetic compass and apply the magnetic variation (printed on the map), you can calculate the direction of TRUE north.
In addition to the revolution of the earth around the sun what contributes to the seasons you experience?
Seasons result from the yearly revolution of the Earth around the sun and the tilt of the earth's axis relative to the plane of revolution. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to go into hibernation or to migrate, and plants to be dormant.
What changes in cosmic ray intensity at earth's surface would you expect during periods in which earth's magnetic field passed through a zero phase while undergoing pole reversals?
Cosmic ray intensity at Earth's surface would be greater when Earth's magnetic field passed through a zero phase because magnetic shifting is minimal. Fossil evidence suggests that the periods of no protective magnetic field may have been as important in changing life forms as x-rays have been in the famous heredity studies of fruit flies.

What has cause the zebra pattern in the rock of ocean floor?
Caused by changes in earth's magnetic field over time, especially reversals of the magnetic poles.
What has caused the zebra pattern'' in the rock of the ocean floor?
Caused by changes in earth's magnetic field over time, especially reversals of the magnetic poles.
What has caused the zebra pattern in the rocks of the ocean floor?
Caused by changes in earth's magnetic field over time, especially reversals of the magnetic poles.
What has casued the zebra pattern in the rock of the ocean floor?
The pattern only appears in images of magnetic field intensity, not really visible. Caused by changes in Earth's magnetic field over time especially reversals of the magnetic poles. "Stripes" represents different ages of rocks as they spread from mid-ocean ridges. Magnetic properties of lavas are set when they cool down and minerals such as magnetite crystallize.

When a solid changes directly into a gas it is undergoing what?
vaporization
What type of substance protects solution and cells from undergoing drastic pH changes?
Buffers, such as sodium phosphate, protects solutions and cells from undergoing drastic pH changes
How do magnetic reversals provide evidence for sea-floor spreading?
The presence of magnetic domains of alternating orientation parallel to the plate boundaries.
How can a rock become another rock?
By undergoing changes, such as weathering and metamorphism.
