Normal polarity

Explanation:

Earth's magnetic field used to be twice as strong 1.5 billion years ago as it is today and Earth's temperature other than what the geologists see from the 'normal' pattern. It has been noticed that some volcanic rocks were magnetized in opposite direction to the direction of the local Earth's field. It is clear that the Earth has experienced the normal polarity 1.5 years ago but at that time, the Earth's polarity was poorly understood.

Suppose you were going to use the design process to build the tree house you designed.whst more would you need to do before you
Tanya [424]
Well, obviously one would need to start off with a plan. After having an idea/blueprint of what your ideal treehouse will look like try finding some measurements for the wood (or whatever material you will use I won't judge) of course you better already have the length, width, and height of your treehouse. After that, you can get building; which could take days or even weeks depending on the house design and the amount of people you have to help out. Once that's done you can paint and decorate it all you want. (of course, to get it in the tree you might need a pulley to put it up there or build the bottom up on the tree.) And all your missing your ladder and that's it.

  • There are two types of speciation: allopatric and peripatric.
  • Allopatric speciation occurs when the species of same population gets isolated that results in lack of gene flow.
  • From the isolated population, new species are formed then it is known as the peripatric speciation.
  • All these isolation of populations and formation of new species depends upon the initial or original group of species that was dispersed.
