Geological time e. Scientific deduction 2. In what ways does geology affect our everyday lives at each of the following: a. Individual: b. Local: c. State: d. National e. Global: 3. Why is Earth considered a dynamic planet? How does the solar nebula theory account for the formation of our Solar System, its features, and evolutionary history? 4. 5. WHICH IS THE CORRECT ORDER OF GEOLOGIC ERAS FROM THE OLDEST TO YOUNGEST (WITH RESPECT TO HUMANS)? a. Mesozoic, Paleozoic, Archean, Cenozoic, Precambrian b. Cenozoic, Hadean, Archean, Ordovician, Jurassic C. Hadean, Archean, Proterozoic, Phanerozoic d. Precambrian, Paleozoic, Mesozoic, Cenozoic e. Mesozoic, Paleozoic, Tertiary, Devonian, HadeanExplanation / Answer
1. The premise that present-day processes have operated throughout geologic time is the principle of- Uniforminitarianism.
Hence the option c is correct.
This principle holds that the laws of nature have been constant through time and that the same processes operating today have operated in the past, although not necessarily at the same rates.
2.
a. Minerals are used in items of daily use like phones, computers, cables, cars, etc.
b. Sand, gravel and crushed stone is mostly used to make concrete to build houses and road.
c. Groundwater deposits essential to sustain life are located under the earth.
d. It helps in detecting and preventing hazards and risks associated with rock falls, radon, landslides, quick clay, landslides and earthquakes.
e. Geology helps us understand climate change in the past, which may help us predict future scenarios.
3. Because there are a lot of things happening inside and on the earth.
4.
It's believed that before our solar system was formed 4.5 billion years ago, a nebula, which is an interstellar cloud of gas and dust, was present in our location. As gravity does with everything, it began to condense the gas into varying regions of density. The denser regions began to grow into clumps of matter, which, over the course of time, would be the seeds for the formation of our sun, planets, and moons.
As gravity condensed the gas, rotation of the gas increased, spreading the gas cloud into a rotating disk that would form the plane of the solar system as we know it today. Evidence of this can be seen because all of the planets revolve around the sun in the same plane and direction.
The center of the disk of spinning gas experienced the least amount of centripetal force, which allowed a majority of mass from the nebula cloud to be attracted to the center by the force of gravity.
Planetesimals, which were early planets, began to grow in size from the clumps of matter and slam into each other as they revolved around the early forming sun. The theory of how our moon was formed lines up with this. It's believed that during the early formation of our solar system, a young Earth and an object about the size of Mars collided, sending debris into space and reforming within Earth's gravity and forming the moon.
