When sediments are buried under deep layers, the increasing pressure from overlying materials leads to a process called compaction. During compaction, the grains of sediment are pressed together, reducing pore space and expelling water. This process contributes to the formation of sedimentary rocks as the sediments become more tightly packed and undergo further cementation, where minerals precipitate and bind the particles together. Ultimately, this transformation is essential for the geological cycle and the development of Earth's crust.

Are mountains hills and plateaus formed in the same way?

No. One way which mountains are formed is due to volcanic activity. Another way is when two of earth's plates push against each other, the ground smashes together and rises up which forms mountains. I believe the Alps were formed this way. Some small mountains can even be manmade.


How glaciers water and wind become agents of erosion and what are their deposits?

Glaciers erode by scraping and plucking rock and sediment as they move, creating u-shaped valleys, cirques, and moraines as their deposits. Water erodes through processes like abrasion and dissolution, forming features such as canyons, caves, and alluvial fans, depositing sediments like sand and gravel. Wind erodes by abrasion and deflation, creating features like sand dunes and ventifacts, with deposits such as sand and silt.


What is the process that creates or causes thunder?

Lightning appears when condensed water (think of clouds) turns into ice crystals and water droplets, and wind smashes this together, because of this energy the wind puts in this hail, positive and negative particles are separated. When there is enough of a charge difference lightning strikes either moving from one part of the storm to another or hitting the ground. Thunder is the sound produced by lightning. It occurs as the lightning instantaneously heats the air to tens of thousands of degrees. The air expands rapidly and sends out a shockwave.

What does nuclear fusion do on the sun?

The nuclear fusion in the sun smashes hydrogen atoms together. The atoms do not combine easily and the fusion (combining of two atoms) can only happen under tremendous pressures by the weight of the material (the gravitational pressures of the star due to its large mass). Here are the steps. 1. Two pairs of hydrogen protons to form 2 deuterons (a hydrogen isotope) 2. Each deuteron fuses with an additional proton of hydrogen to form helium-3 3. Two helium-3 nuclei fuse to create beryllium-6, but this is unstable and disintegrates immediately into two protons and a helium-4 4. the two protons, together with other hydrogen protons, can then form 2 deuterons and the process starts again. Whenever the fusion takes place, mass is "destroyed" as the result is energy which is released through radiation. The above method is the primary nuclear reaction in our sun. There is also an alternate method which larger stars use called the CNO cycle, but it requires a much larger mass than our sun (about 50% larger) to initiate.
