Answer:
A fold is a bend in the rock strata. Folding: This Is a type of earth movement resulting from the horizontal compression of rock layers by internal forces of the earth along plate boundaries. An unfold are termed as anticlines. The downfolds are termed synclines. Folding.
What speech, this needs an attachment.
Answer: Two hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released.
Explanation:
All stars (including the Sun) at birth begin to fuse two hydrogen nuclei to form helium through nuclear fusion.
In this sense, nuclear fusion is the union of two light atoms, releasing energy in the process, which is the cause of the great luminosity of a star. Especifically, the hydrogen nuclei will begin to fuse, generating helium nuclei in the process and releasing huge amounts of energy.
To unerstand it better:
To shine, the stars transform their hydrogen into helium by means of nuclear fusion. When at half of its life a star is without hydrogen, the nucleus becomes entirely helium and the star declines, becoming colder and brighter due to the energy generated by the nuclear reactions, then the star begins to contract.
Nevertheless, if the star is bigger, this helium will be also consumed and the nucleus transformed in Carbon, then in Oxigen, and so on. Being the last transformation Iron until the star delivers all its energy.
Answer:
The natural gas is used more often because it is much more environmentally friendly.
Explanation:
Most of the world, in order to produce energy for whatever purpose, mostly relies on usage of fossil fuels. The fossil fuels that are the most dominant when it comes to usage are unfortunatelly the ones that cause the most pollution. Those two fossil fuels are the coal and oil. There is another fossil fuels though that has always been in the background but is gradually becoming more and more popular.
The fossil fuel that starts to gain more ground is the natural gas. The natural gas is relatively abundant, easy for usage, transportation, and economically justifiable. What is also very important and gives it an advantage lately is the fact that the pollution form it is uncompearably lower, in fact, the methane that is released from the natural gas only does so because of leaks during its transportation.
The correct answer is - B) wave erosion.
The beach erosion is a direct result of the wave action on the coastline. The waves are very powerful when it comes to erosion, and this is because they have big power, and also the chemical components of the water that are very effective too.
The sheer power of the waves contributes to the direct breaking of the rocks into smaller pieces over time, while the water itself, is reacting with the rocks on a chemical level and slowly decomposes them. As the rocks are getting smaller and smaller because of the erosion, the tiny fractions of sand particles are forming the beaches along the coastlines.
