True not false i know i missed it and put false
Carbon dioxide (CO2) makes up the vast majority of greenhouse gasemissions from the sector, but smaller amounts of methane (CH4) and nitrous oxide (N2O) are also emitted. These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce electricity.
Answer:1st Big Bang 2nd Sun got borned by millions of tiny stars,space materials all collided together.3rd sun is in our solar system 4th in the future scientists don’t know when but the sun will get bigger swallowing almost all of our solar system (not the universe) and will blow up this is the natural life cycle of the sun predicted
Explanation:
The convection cell in the mantle is essentially the self-sustaining, constant movement of the magma inside this layer. This works in a very simple way. The hotter magma is less dense, so it is pushed upward toward the crust above it, while the cooler magma is denser, and it moves downward where it gets hotter, and the process goes on and one. The magma that goes upward toward the crust, manages to push through the thinner and cracked crust between the plates that move away from each other, thus on the divergent plate boundaries. As the magma penetrates through the crust it manages to get to the ocean floor, thus causing volcanic activity. This magma cools of very quickly and creates new crust. Because the magma constantly rises up and creates new crust, the crust piles up and forms an underwater mountain of volcanic origin that constantly has volcanic activity because of the rising magma. This volcanic underwater mountain range is called mid-ocean ridge.
Explanation:
<h3>Despite its electronegativity, size of a chlorine atom is larger and hence, the electron density is low. So, HCl does not have hydrogen bonding but, HF,NH3,H2O shows hydrogen bonding.The hydrogen bond does not form because the chlorine atom is too large. Despite chlorine's high electronegativity its big size lowers the negative charge density and it is not enough to attract a hydrogen atom in a stable phase. Nevertheless, there is a small dipole-dipole attraction between adjacent HCL molecules.</h3>
