Stars A star is a massive‚ luminous sphere of plasma held together by gravity. The nearest star to Earth is the Sun‚ which is the source of most of the energy on the planet. Solar System The Solar System consists of the Sun and its planetary system of eight planets‚ their moons‚ and other non-stellar objects. It formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. The vast majority of the system’s mass is in the Sun‚ with most of the remaining mass contained

To what extent does personal or ideological bias influence our knowledge? How would one rate the effectiveness of their personal experiences or ideological bias on their knowledge claims? Most people would think their knowledge claim is a true belief‚ but without some form of proof‚ data‚ or authority verification it is not a true knowledge claim. It is known that what distinguishes knowledge from belief is truth‚ but if you only believe a portion‚ it may be true or false. Therefore‚ it should

Climate Change and the Philippines Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions‚ or in the distribution of weather around the average conditions. Climate change is a “change in climate which is attributed directly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability

Harnessing of Solar Energy: Photosynthesis versus Semiconductor Based Solar Cell Photosynthesis and semiconductor-based solar cells are both used to harness solar energy from the sun – photosynthesis for plants and semiconductor based solar cells for human beings. Photosynthesis consists of light reactions and dark reactions. It is a process in which carbon dioxide (CO2)‚ water (H2O) and light energy are utilized to synthesize an energy-rich carbohydrate like glucose (C6H12O6) and to produce
