There are two different answers, 1, water wears away the rock slowly over time, allowing you to see the levels odsilt, sediment, ash, Ect, over time, it's a time machine.
a river is also a natural rock tumbler, it breaks, polishes and carries minerals down stream.
Answer:
It took climate change, fertile river valleys, domestication of crops and animals so that the hunter-gatherers became sedentary farmers.
Explanation:
Initially, all humans were hunter-gatherers. This was due to multiple reasons, with one the biggest one probably being the climate which was not enabling good conditions for the hunter-gatherers to transform their lifestyle. All other conditions needed were stopped because of the climate conditions, so humans had to do what they could to survive in those conditions.
About 10 years ago though the bad climate conditions ended, or rather the Ice Age ended. This resulted in a much warmer climate, which in turn created much more water bodies like rivers and lakes, much more vegetation, and they contributed to the creation of much more fertile soil.
With these conditions in place, the humans quickly saw that there is huge potential in some plants and animals, so they started to farm them, select the ones with the best characteristics, and gradually producing enough food for themselves. With the food problem solved, humans didn't have the need to wonder around all the time, so they started abandoning the hunter-gatherer lifestyle and started settling in one place.
Answer:
x = 16
Explanation:
Since ΔFGH and ΔKJH are similar, let's compare their sides.
So that;
= 
= 
cross multiply to have;
32(4x - 25) = 52(x + 8)
128x - 800 = 52x + 416
128x - 52x = 416 + 800
76x = 1216
x = 
= 16
x = 16
Therefore, x = 16.

Answer:
The correct answer to the question is that although scientists have studied meteorites and know that there are two major types, they are still unsure of the exact location from which they came.
Explanation:
Meteorites, Meteors, and Meteoroids, are types of space rocks, that have been classified by science according to where they are at a certain point in time. A Meteoroid, is the name given to the space rock that is still outside of the Earth´s atmosphere, and it can be as small as sand grains, or as big as an asteorid. A Meteor, is a piece of a Meteoroid that enters the atmosphere, and while most are burned against the planet´s surface, some make it in and can be found. When the piece makes into Earth, and hits the ground, they are known as Meteorites. Scientists know exactly the origin of these rocks (planets, stars, asteroids, moons) and they can calculate their general locations. But what they still cannot predict with certainty is the exact location from which a Meteoroid, or asteroid, will come from.
Unlike Earth, Venus lacks plate tectonics to form volcanoes known as "compound volcanoes." Instead, Venus' geography is characterized by "shield volcanoes" generated by hot spots is the difference between volcanism on venus and that around the ring of fire on earth.
Mars and Venus have only shield volcanoes. On these planets, geological processes are vertical and plate tectonics, and significant horizontal tectonic movements do not occur.
The presence of CO2 in Venus' surface atmosphere indicates that volcanism is currently active and clouds of SO2 and sulfuric acid are present.
First, because of the high pressure, Venusian lava requires a much higher gas content than terrestrial lava to explode. Second, the main gas that causes lava explosions on Earth is water, much less so on Venus. Finally, many viscous lavas and explosive eruptions occur near Earth's plate subduction zones.
