True, the Earth's axis runs from the north pole to the south pole.
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.
The Tropic of Capricorn (or the Southern Tropic) is the circle of latitude that contains the subsolar point on the December (or southern) solstice. It is thus the southernmost latitude where the Sun can be directly overhead. Its northern equivalent is the Tropic of Cancer.

Answer:
The stream will flow fastest between 2 and 3.
Explanation:
On this map, we can see two basic elements, one being the contour lines, and the other being the color with which a stream is presented. The contour lines are giving us a good representation of the relief and where it is steeper and where it is less steep. Basically, where the contour lines are closer to each other, we have a steeper relief, and when the contour lines are further away, the relief is less steep.
The water moves under the influence of gravity, so downward. Where the steepness is the greatest, the gravity influences it the most, so it moves faster, while where the steepness is smaller, the gravity influences it less, so it moves slower. On this map, the contour lines are closest to each other between points 2 and 3, meaning it is the steepest part of the relief, and it is the place where the stream flows the fastest.
Answer:
The K-T extinction event is the global mass extinction that has taken place about some 65 million years back due to the asteroidal impact. This mass extinction event has wiped almost 75% of the plants and animal species from the earth's surface. The dinosaurs were extinct and very animal species have survived and undergone evolution in due course of time.|
The Cenozoic era started after the K-T mass extinction event, i.e from about 65 million years to the present.
Thus, the Cenozoic era is also known as the age of mammals because mammal were more abundant and diverse then. Many flowering plants evolved during this time and the earth experienced global cooling.
