No, The magnetic north shifts overtime due to the rotation of liquid iron in the earth! So your answer would be No they are not always the same distance apart! Hope this helps :)
The correct answer is - B) wave erosion.
The beach erosion is a direct result of the wave action on the coastline. The waves are very powerful when it comes to erosion, and this is because they have big power, and also the chemical components of the water that are very effective too.
The sheer power of the waves contributes to the direct breaking of the rocks into smaller pieces over time, while the water itself, is reacting with the rocks on a chemical level and slowly decomposes them. As the rocks are getting smaller and smaller because of the erosion, the tiny fractions of sand particles are forming the beaches along the coastlines.
Useful satellite data concerning sea ice began in late 1978 with the launch of NASA's Scanning Multichannel Microwave Radiometer (SMMR) satellite.
1) Hunting: People can over-hunt a species killing too many of them too fast.
2) Global warming: A place can get to hot for them to survive their anymore like coral reefs for example.
3) Destruction of habitats: This can leave animals defenseless and open to attack.
The correct answer is - Layer 2 and layer 9 are the same relative age.
On this image we can see multiple layers that have been cut through and displaced by a fault. The layer 2 and the layer 9 despite not being at the same level, with level 2 being closer to the surface, while layer 9 deeper into the ground, we can still see signs that they actually have the same relative age.
We can notice that these two layers have the same relative age because of two things. The first thing is the index fossils, with both of these layers having the same fossils from the same geologic period. The second thing that gives us a clue is their composition which is pretty much identical, thus indicating of a same geological period.
