Photosynthesis begins when chlorophyll molecules in the plant absorb light energy from the sun. Along with sunlight, CARBON DIOXIDE (CO2)/OXYGEN (O2) and HYDROGEN (H)/WATER (H2O) are also taken in by the plant. Light energy from the sun FUSES/SPLITS water molecules (H2O) into hydrogen (H) atoms and oxygen (O) atoms. Pairs of oxygen atoms combine to form oxygen gas (O2). The oxygen gas (O2) leaves the plant as a WASTE/SUGAR product. The carbon dioxide (CO2) and hydrogen (H) molecules are made into WASTE/SUGARS, which are used by the plant to make energy. Also during this process, light energy from the sun transforms into THERMAL/CHEMICAL energy that is stored in sugars.

Climate is different from the weather. Climate is the long term weather condition and weather is short term atmospheric condition. The annual precipitation is report is depicted as graphical data. Transformation of water vapor to liquid droplets in air is called condensation.

What is climate?

Climate in a region is the long term weather exists there and which will be characteristic for that region. Weather is forecasted for a day or a particular time, reporting the short term atmospheric condition. Climate of a locality depends on the landscape there, local winds etc.

The annual precipitation report determined by the summation of monthly precipitation data and which in turn obtained by the summation daily precipitation for each month and it is depicted graphically to analyse.

The transformation of water vapor to liquid droplets in the air is called condensation. The gaseous molecules of the water vapor condense together to form the liquid droplets.

Answers

Answer: No. The ball wil not bouce back to you. A ball is similar to how light behaves because when you bounce a ball, it will go in a straight line and when it hits something, it will bouse again and go somewhere else. This is also how light behaves.

Explanation:

The ball will not bounce back to you. It will bounce again but go somewhere else similar to the way light behaves.

What is the scattering of light?

When a beam of light travels through a medium, it hits the particles in them. Some of the light rays get absorbed while a few rays get scattered in various directions. The intensity of the scattered light depends on the size of the particle and its wavelength.

When light reaches matter, it can be refracted, reflected, absorbed, or scattered. Light travels in the same direction after hitting the surface is reflected light since the surface is smooth but never follows the same path.

Scattering happens when light bounces off an object or particle in a variety of directions. A ball shows behavior as light. When you bounce a ball, it follows a straight path and hits something, it will bounce again but in a different direction. That is how the light behaves.

Answers

Answer:Melting.

Freezing.

Evaporation.

Condensation.

Sublimation.

Explanation:

Answer: Examples for the five transformations previously given.

For the first four, we encounter common examples in everyday life, all to do with water:

Freezing - liquid to solid, e.g. water to ice, e.g. making ice cubes.

Melting - solid to liquid, e.g. ice to liquid water, melting ice cubes or snow flakes.

Condensation - gas to liquid, e.g. water vapor (gas) to liquid - water vapor in air (humidity) condenses to form liquid droplets on the outside of a cold beverage glass on a hot humid day; or cloud formation in the atmosphere.

Evaporation - liquid to gas, e.g. liquid water on clothes evaporates as clothes dry on clothesline or in dryer

While water can sublime under certain conditions of temperature and pressure, it is less evident in everyday life. Carbon dioxide however is a more common example.

Sublimation - solid to gas, e.g. "dry ice" disappearing. The visible smoke associated with dry ice is most likely just condensing water vapor in the air as the solid carbon dioxide cools the air.
