The two tools used are:
- A relationship existence between a galaxy's distance from Earth and also that of its speed.
- The findings in the 1960s of the presence of cosmic microwave background radiation.
<h3>What evidence is collected by each tool?</h3>
The evidence to support the big bang are:
- There was found to be some red shifts of a lot of galaxies which connote that the universe is widening.
- Due to the widening of universe, new elements were formed such as hydrogen, deuterium and others.
- Microwaves were found by orbiting detectors.
Therefore, The two tools used are:
- A relationship existence between a galaxy's distance from Earth and also that of its speed.
- The findings in the 1960s of the presence of cosmic microwave background radiation.

In March 28, 1964 at Alaska with a 9.2 magnitude
We know that the poles had changed positions in the past, because of the arrangement of the crystals in the rocks made out of metal. The crystals of the metals act like the needle of the compass when the rock is cooling off and forming, they turn into the direction of the strongest magnetic field on the Earth, which is the North Pole. So by studying the rocks that are made out of metals and see the crystals arrangement and also estimate the age of the rocks, the scientist can precisely tell how has the North Pole been moving throughout time.
Answer:
Bathymetry
Explanation:
Bathymetry is the study of underwater depth of ocean floors or lake floors. Basically bathymetry is the underwater equivalent to topography
