When we see a region that is not as heavily crunched in on its surface as other regions, we conclude that there is a larger force pushing it into a different shape. This conclusion is made based on the fact that there is less land land-side-up and upside down compared to other terrestrial planets.
The discovery process for this phenomenon is called geophysical detection. During this process, scientists look for changes in the environment, such as changes in the temperature or composition of water and life. When they find evidence of these changes, they conclude that there was a large force that shaped the planet.
This change in shape can be dramatic or subtle, it does not matter because when people see it, they assume that something impactted it into a different shape.
This article will talk about some examples of geophysical detection and how it confirms hypotheses about planetary shapes.
The heavily cratered regions have not had as much tectonic activity
When we see a region that is not as heavily cratered as the rest of the planet, we conclude that there has not been as much tectonic activity in that area.
We think that there must have been more movement in that area over the past few million years because it is so heavily cratered.
This movement could have taken place via plate movement, meteorite impacts, volcanic activity, or all of the above. We believe this because we see little to no mountains in these regions and we are not seeing any heavy rainfall or snowfall either.
When looking at satellite images, we can see if there has been heavy rainfall or snowfall on the ground for those areas. If so, then we would notice it on the images.
The heavily cratered regions have higher elevations
When we see a region that is not heavily cratered, we assume that it is higher in elevation. We conclude this because when we measure the elevation of a region, it shows more rock and snow than other regions.
We believe that this raises the temperature of the area and increases the amount of heat radiation coming out from the area. This heat radiation would then raise the temperature of the surrounding area, and thusly, usenethesis.
We believe this happens more often in colder areas because there is less internal heat radiating from them. This reduces our need for furnaces or stoves to retain enough heat during summer days, which is when we see rashes and burns coming out from them.
When looking at regional temperatures, we must take into account weather reports as well as our own findings.
The heavily cratered regions have weaker gravitational pulls
When we see a region that is not heavily cratered, we conclude that it has a weaker gravitational pull. This is the case when we see less massive continents floating in the sky.
We believe this because when there is a heavier crust, it has a stronger gravitational pull. This makes parts of the planet harder to orbit. When satellites need to be maintained or construction needs to take place, that must be done with some effort.
Satellite maintenance and construction does require technical skills, so it seems likely that there were people who worked at NASA and elsewhere who had those skills. We believe this was the case for continental movements because NASA reports them as such.
We can determine which areas of a planet would be best for settlement based on which areas are most heavily crusted
The heavily crusted areas are presumed to be the most habitable. This is based on the fact that it would be more difficult for life to survive and grow on a lessly crusted planet.
Since there are only a few highly habitable planets in the Milky Way, it is important that we find a planet that is sufficiently crusted so that we can determine if it is inhabited.
We believe that if life was present, it would have developed similar to how Earth’s own life forms evolved. These include multicellular organisms with complex social organization such as ourselves.
We believe our presence on this less than hospitable planet may have triggered further evolution of life there so we may see signs of humans in the future.
We can determine which areas of a planet would be best for mining based on which areas are most heavily crusted
When we see a region of a planet that is not as heavily cratered as the rest of the planet, we can conclude that it would be a better place to mine. This is because we can determine which areas are most heavily cratered.
These areas contain very valuable minerals such as gold, copper, lead, and zinc. These minerals are very rare and valuable. Because of this, there is a higher demand for these minerals.
Because of this demand, countries will go to great lengths to obtain these materials. This continues to raise the price of materials making them more expensive to obtain. Because of this effect, more expensive metals such as copper and lead will be sought after.
This is why we can see regions on planets that are not heavily cratered as having a warmer feel than other regions.
Regions with weaker gravitational pulls will likely have lower density atmospheres and thus less protection from the atmosphere for settlers and miners
When we see a region that is not as heavily crated as other regions, we conclude that it may not be as heavily protected. This is the case when we see large areas of water, open lands, and sparse or missing oceans.
These areas are typically more vulnerable to disasters such as global warming or volcanic eruptions. We can look at these events with a little confidence because they have not ended in disaster.
Global warming has happened before and will happen again, and while it may not be totally reversible, having less safety in place makes it less likely for a crisis to occur.
Having less safety in place also helps reduce conflicts between groups as they need to protect themselves and/or supply and services.
