Explain the distribution of the world’s major geophysical hazards. Some parts of the world are more often and more severely afflicted by natural hazards than others due to the geological structure of the Earth. The earth’s crust is made up of seven major plates and a number of minor plates. The plates move because of the convection currents in the mantle caused by temperature differences within the mantle‚ leading to volcanoes and earthquakes‚ the world’s major geophysical hazards. The movement

In other words‚ over transfer of food and the increase in salt density can raise water lichens and may change water living species. 8. The species may change parallel to the erosion caused by the human activities or the permanent increase in the water turbidity as an outcome of the dam construction. 9. Discharge of toxic matters (pesticides‚ toxic metals etc.) and their condensation in food chain may affect sensitive animals immediately; all

The Human Cost of an Illiterate Society The Human Cost of an Illiterate Society by Jonathan Kozol‚ is an article which illustrates the reality for millions of Americans‚ and the impact illiteracy has on the overall population and that individual and their family. Kozol draws emotional and personal stories which impact the reader as well as allude that the lack of literacy is in direct correlation with Democracy and how illiterate people will vote‚ if they even do at all.

The changes in the diffusion of Buddhism and Hinduism through 600 CE greatly impacted these religions such as the popularity of the religions in India and where the religions was being diffused; however‚ a few continuities existed such as they both originated in India. Since Hinduism reinforces the caste system and Buddhism believe in equal treatment of all people which opposes the caste system‚ Buddhism started to spread into other areas other than India to offer an alternative to Hinduism for

1 Diffusion is the movement of molecules (or ions) from a high concentration to low concentration. Diffusion is form of passive transport as energy does not need to be generated. Diffusion is complete when the concentration of molecules is equal on either side of the membrane. Diffusion rate can be influenced by many factors such as: Concentration gradient across the the membrane. Permeability of the membrane to the diffusing substance. Temperature. Surface area of the membrane. Question 2 2.1

Experiment 1 Background Diffusion is a process‚ in relation to the spontaneous movement of molecules from an area of high concentration‚ to an area of low concentration down a concentration gradient. It is a type of passive transport method‚ that requires no cellular energy (ATP). This movement occurs‚ until a state of equilibrium has been established on both sides of the membrane. The diffusion of molecules happens at cellular level‚ through a cell membrane via the pores. The cell membrane

he mass and length of the potato piece must be kept the same in each experiment primarily because they affect the surface area of the piece‚ and varying surface area could have a great effect on the rate of osmosis. This is because in an experiment where the potato chip has a large surface area‚ there is a larger area of partially permeable membrane and therefore more opportunity for water particles to pass through. I will keep the surface area the same by keeping the mass and length

Thomas Graham studied the behavior of the diffusion of gases of unequal densities when placed in contact with each other‚ using air as his control. He wanted to numerically prove how the diffusion of the gas volumes was inversely proportional to the value of the density of the gas‚ under constant temperature and pressure. The significance of this experiment was that in led to a reevaluation of the concept of the movement of matter‚ realizing that diffusion dealt with small immeasurable elements of

Crime and Geography CRIME MAPPING Crime mapping is how we detect areas with crime. In Crime Mapping‚ it focuses on identifying places or areas where crime is high or low. Mapping crime is helpful as police can track down which areas in a city‚ town or country has high risk of crime. When a crime has been committed‚ the crime will be plotted on a map with information like when the crime was made‚ what offence was made and who the offender was. Currently‚ Crime mapping has been used actively
