- Greenhouse effect is the process by which radiations from the sun are absorbed by the greenhouse gases and not reflected back into space. This insulates the surface of the earth and prevents it from freezing.
- Acid Rain as the name suggests can be said to be the precipitation of acid in the form of rain in the simplest manner. When atmospheric pollutants like oxides of nitrogen and sulphur react with rainwater and come down with the rain, then this results in Acid Rain.
- Global warming is a gradual increase in the earth's temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.

Bohr’s Model of Atom
- According to Neil’s Bohr the electrons could revolve around the nucleus in only certain orbits known as discrete orbits of electrons, each orbit having different radii.
- When an electron is revolving in a particular orbit around the nucleus the electron does not radiate energy.
- Bohr’s model of an atom can be described as follows:-
- An atom is made up of three sub-atomic particles – protons, electrons, neutrons.
- The protons and neutrons are located in a small nucleus in the centre of the atom.
- The electrons revolve around the nucleus rapidly in fixed circular paths called energy levels or shells.
- There is limit in the number of electrons that each shell can hold. It is given by the formula 2n2, where n = orbit number or energy level index.
- Each energy level is associated with a fixed amount of energy.
- There is no change in the energy of the electrons as long as they keep revolving in the same energy level, and the atom remains stable.

Movement of any object from one position to another position with respect to the observer is called as Motion. Motion Along a Straight Line: When an object moves along a straight line, the motion of the object is called rectilinear motion. For example; motion of a car on highway.

An octopus is a soft-bodied, sea creature with a bulbous head and eight arms, hence it is named as the octopus. The name octopus was originally derived from a Greek word meaning number eight. Octopuses are carnivores, which feed on other creatures available in their area including clams, shellfish, shrimp, lobsters, fish, sharks, and even birds. These sea creatures are found in all oceans and usually live on the ocean floor, within shells, crevices, and reefs.

Mitochondrion possesses double membrane as its covering. The outer smooth surface and the inner membrane forms infoldings called as cristae, which increases surface area for more formation of energy in the form of ATP.

g=10 m/s^2
m=50 kg
h=5m
t=4s
Then
W=mgh
=50×10×5
=2500 N
Now,
Average power=total work done / time
=2500/4
=625 J s^-1

Dalton's atomic theory suggested that the atom was indivisible and indestructible. But the discovery of two fundamental particles (electrons and protons) inside the atom, led to the failure of this aspect of Daltons atomic theory.

The postulates of this theory may be stated as follows:
- Matters are composed of very tiny particles called atoms.
- These particles are too small to see and cannot be created or destroyed in a chemical reaction.
- Atoms of a specified element are identical in mass and chemical properties.
- Atoms of different elements have different masses and chemical properties.
- Atoms combine in the ratio of small whole numbers to form compounds.
- The relative number and kinds of atoms are constant in a given compound.

According to Thomson Model of an atom:
1)An atom consist of a sphere of positive charge with negatively charged electrons embedded in it.
2)The positive and negative charges in an atom are equal in magnitude,due to which an atom is electrically neutral.IT has no overall positive and negative charge.

Fixed capital is also called a "fixed investment" and encompasses assets that are used continuously during the business's operation, according to the Business Dictionary. For example, the equipment used to produce merchandise would constitute fixed capital because it is not depleted with each use.

In humid weather it takes longer time to dry wet clothes because the moisture and water vapour are present in humid weather they gets slight absorbed by the clothes and clothes maintain their wetness due to this they take a longer time to dry and in humid weather they don't get enough sunlight to dry themselves at a faster or normal rate, so they take a long time due to these reasons.

There are 366 days in a leap year. A year usually has 365 days. The extra day is needed to keep the calendar "in synch" with the Earth's orbit around the Sun. The Earth takes about 365 and a quarter days to orbit the Sun once. The extra 6hours is not included in each year. Thus leap year comes once in every four years including an extra day(24 hours) that is 29th February including the extra 6hours from each 4 revolution time periods.

In this process, the soil particles are loosened or washed away in the valleys, oceans, rivers, streams or far away lands. This has been worsening due to human activities such as agriculture and deforestation.
Soil erosion is a continuous process that occurs either slowly or at an alarming rate. It results in a continuous loss of topsoil, ecological degradation, soil collapse, etc.
