Answer:
Mercury has the widest variation in surface temperatures between night and day of any planet in the solar system.
Explanation:
Answer:
Sea floor spreading theory is given Harry Hess the line of evidence that support this are given as under.
Explanation:
Evidence from Molten Matter
In the 1960s scientists found that there is a presence of new materials from below that need the lava to be uplifted and spread along the boundaries of mid-oceanic ridges i.e the lava or magma spreads through the active plate margins of both plates. The red sea is newly formed is an example of spreading, <u>(a process of oceanic basin creation)</u>.
Evidence from Magnetic strips
The magnetism of the earth helped the scientists study the process of seafloor spreading as the newly formed lava gets deposited on either side of the ridges it takes the magnetic properties of the earth. The ocean floor is divided into strips of north and south after cooling.
Active and passive plate margins.
The tri-junction of plates and newly discovered plate like that od red sea and splitting of the rift valley and transform faults. Movement of continents away from each other. Examples include Eastern pacific rise and Mid Atlantic ridge.
True, A 'planar projection map' is helpful for sea navigation.
<u>Explanation:
</u>
A 'planar projection map' that shows the particulars of the globe in a flat surface projection. The pictures projected by the map are shown in rectangular-shaped. If any other map such as Cylindrical map is used then, the edges are not so perfect, they show distortion. With the help of all three coordinates, it shows a 3-D picture of the globe and its objects which can be considered almost as real as the actual object. They are also known as azimuthal projections and are mostly used in projecting polar regions.
The full moon cycle (from one phase to the same phase again), from start to finish, is generally 28 days. That being said, from one phase to its opposite, or one half-cycle, would be approximately 14 days.
