This is because Earth is shaped roughly like a pumpkin and getting a flat piece of paper to accurately resemble the entire surface of a pumpkin isn't easy. You can get an idea of the difficulties involved by drawing a picture on an inflated balloon. Then, stretch the deflated balloon ...
Because these early conditions resembled early Earth, the question of life on Mars is particularly interesting. If life did not arise on Mars, why not? Comparison with conditions on Earth suggest that differences in length of ocean coastline and probable tidal ranges resulted in limited availability...
The Cretaceous period was only separated into the Early Cretaceous and Late Cretaceous because of the longevity of many species during this time. Flowering plants started to dominate, and some of the largest dinosaurs began a long reign across the world. The world also began to resemble the dist...
Although its goals resemble those of the delta-SES research, socio-hydrology is not (yet) studying deltas-as-SES because of its limited focus on human response patterns in floodplains. Therefore, it cannot really assess the sustainability of delta-SES, although Ciullo et al. (2017) come clos...
(CO2), much like the Earth's did at a distant point in geological history. As you have surely heard, CO2is a greenhouse gas and traps heat very effectively. This, combined with Venus's being so close to the sun, results in temperatures of close to 900° F (475° C). Venus is ...
did see this one incident where there was a massive increase in oxygen due to photosynthetic bacteria that emerged at that time that filled up the atmosphere for the first time with oxygen. The oxygen scavenged all the early methane, which is a potent greenhouse gas and the earth cooled dow...
If a rock did have preferences or goals, we would arguably be able to speak of it having interests. Such interests might still not qualify rocks for moral standing, but the interests of other non-sentient entities might matter. 5 Making decisions under uncertainty The discussion so far ...
Key questions: What did the early Universe look like? When did the first stars and galaxies emerge? The Hubble Ultra Deep Field of galaxies. A new study of the star formation activity in 179 of the galaxies in this image including many dating from about six billion years ago confirms an ...
Empedocles argued that all matter was composed of four elements: fire, air, water, and earth. ... For example, regardless of how many times you break a stone in half, the pieces never resemble any of the core elements of fire, air, water, or earth. What were Aristotle's ideas? Arist...
Where is the biggest impact crater on Earth? What did the Lunar landings discover about the moon? What Apollo flight landed on the moon? How big is the Woodleigh crater? How is an impact crater formed on a planetary body? As early as the 17th century, Galileo saw ringberg (craters) on...
