Energy from Sun in the form of electromagnetic radiation in the fundamental driver of the earth¿s Climate system. The total Solar Energy hitting the Earth depend on its distance from the Sun the distribution of the radiation over the globe depends on the tilt and precession. the amount of energy arriving in summer at high latitudes determines weather the winter growth of the ice cap will recede or wetter the climate will be precipitated in to an ice age. Thus change to seasonal irradiance. the total solar energy hitting the Earth depends on it¿s distance from the Sun. The Sun has an effect on climate since it¿s radiation in the main energy source of our Planet.

The effects of eutrophication on the environment may have deteriorate consequences of health of exposed animal and human populations through various path way¿s. when fresh water, extracted from eutrophic areas, is used for the production of drinking water severe impacts can also occur during watering in eutrophic waters. eutrophication is complex processes which occurs both in fresh and marine waters, where certain types of algae disturbs the aquatic ecosystem and become a threat for animals and human health the primary cause of eutrophication is an excessive concentration of plant nutrient¿s originating from agriculture of sewage treatment. The main cause of eutrophication is the large input of nutrient mixed to water body and the main effect is imbalance in the food web that results in the high levels of phytoplankton, zooplankton, algae biomass in stratified water bodies. This can lead algal blooms. The direct consequences is in an excess of oxygen consumption near bottom of the water body .

Human activity can affect were quality at pass through the water cycle. Water is our most recycled resources. The amount of water on earth is basically constant, but the distribution of water changes over time and space due to a dynamic processes called water cycle or hydrological cycle. The water cycle or hydrological cycle powered by solar energy and gravity. Our planet warmth from the sun causes evaporation of water from lakes; stream and soils. Solar energy also drive a processes called transpiration-the release and evaporation of water from tiny pores in leaves of plants. Evaporated and transpired water vapour is stored in atmosphere until it condenses and is pulled by gravity back to earth as rain, sleet, snow, hail, dew or frost up to 80% of this precipitated water is returned directly to atmosphere by evaporation. The rest many runoff over land and in to lakes and stream or may soak up in to ground. Some of water that soaks in to ground stay in unsaturated zone. This zone is work or soil layer in which some of the space between particles are filled with air and some are filled with water.

The effect of solar energetic particles and radiations in the interplanetary space and on the earth, termed as space weather, is an active area of research in global communication and space exploration. The Sun influence our entire lives and also our environment. Since ancient times, human kind has been conscious that the life on earth is sustained by Sun. the central role played by our star in influencing the course of events on this planet. the Solar interior and exterior, particularly highlighting various transient. The sun influence on the earth can seen by the interplanetary magnetic field and the solar wind. The magnetic field on the sun is the root cause of the emission structures and their variation. The plasma from the sun¿s corona, called the solar wind rushes out in to interplanetary space, which contains an imprint of the Sun¿s magnetic field. Mainly Interplanetary magnetic field responsible for changes of environment of earth. Interplanetary magnetic field has spiral from and field can mention Sun inclination 7.5 degree seen from earth and interplanetary field line. Directed the opposite for both Sun itself Sun hemisphere.

Solar activity occur transient phenomena affect on earth thus Solar radiations affect the total electron content of the ionosphere that may disturb the radio-frequencies used in telecommunications. It may state with full confidence that the increase in the critical frequencies of the F2 layer from the values observed in the morning hours to the afternoon maximum frequencies, is due to ultraviolet (UV) radiation from the Sun. During an ionospheric storm, some radio frequencies are absorbed and others are reflected, leading to rapidly fluctuating signals and unexpected propagation paths. In the present work, we have shown that the effect of various solar activities that effects the electron densities of the ionosphere and how they affect our telecommunication system. During solar maximum.
