Deformation events like folds, faults and igneous intrusions that cut across rocks are younger than the rocks they cut across.
Based on some prior knowledge some of these deformation events that I can think of would come from thousends of years of water erosion is the only thing I can think of. I just want to know what other ways, that are not man made, that expose these sediment layers?
Stratigraphy is the study of layered sedimentary rocks
I remember learning about this in another geography class I took at Wright. It is very intersting to see the history of a loctation just based on their layers of sediment over the hundereds of thousands of years.
Geoscientists use the geological time scale to assign relative age names to events and rocks, separating major events in Earth’s history based on significant changes as recorded in rocks and fossils.
It is always interesting to see thes different layers of rocks and sediments on wonder what the earth looked like back during the formation of each individual layer.
This temperature differentiation resulted in the inner four planets of the solar system becoming rocky, and the outer four planets becoming gas giants.
Just thinking if our planet was either closer/farther away from the sun, what would our planet look like? Would it still have us humans on it?
redshift
It is very interesting to see two different things, being sound waves and light waves, be compared using the dopplers effect. In my day to day life I am exposed to the Doppler effect contently when people honk while driving by my work or when a siren goes by. For that effect to be used to find the speed and direction of galixes is mind boggling.
Some groups of people argue that some established scientific theories are wrong, not based on their scientific merit but rather on the ideology of the group.
This happens all the time, especially in the case with the tectonic plate theory that shattered how scientists viewed our world.
Geology plays a key role in how we use natural resources
This is especially important due to the fact that we uses these resources on a daily basis with gas an so on. We also wear the products that are produced from sed resources.
Science is more than just a body of knowledge, science provides a means to evaluate and create new knowledge without bias
I can't agree more with this statement mainly because science is where we, as humans, base a lot of our understandings on. We have come so far to finding different organisms, finding cures, and even splicing DNA for crops for the betterment of the human race and to further advance our knowledge. From this, I hope that I gain a better knowledge of the earth science field as a whole.
