Hello

WRITE CAUSES AND CONSEQUENCE OF ANY 2 NATURAL CALAMITIES.

1) eathquake

earthquake is the natural calamities where there is the vertical and horizontal shaking of the

earth crust. it is cause due to overlappibg of the different plates that are present in the earth surface. when this plates intersect or expand the earth occurs

consequences are it causes loss of life and human property , degards the environment , it leads to flood, landslides etc The damage caused by earthquakes is from ground shaking, ground rupture, landslides, tsunamis, and liquefaction.

Next - volcanic eruption

its is the out flow of the larva from the inner of the earth to other surface. it is cayse due to high pressure exerted on the surface of the earth that leads to explode the inner larva.

its consequences are it degards the environment and loss of the beauty of the nature , there is loss of human life , widlife , etc. volcanic eruption include infectious disease, respiratory illness, burns, injuries from falls, and vehicle accidents related to the slippery, hazy conditions caused by ash. When warnings are heeded, the chances of adverse health effects from a volcanic eruption are very low.

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
