Earthquakes are considered one of the most deadly natural catastrophes that can affect human life. Most often, a quake occurs in earthquake-prone zones where two tectonic plates meet, split, or slip by one another; the type of plate contact determines whether the earthquake will be shallow or deep. During the …

The main reason we study coasts is because they are rapidly changing due to four costal erosion processes: hydraulic action, attrition, corrosion and corrasion. All of these are generated by waves and their power. Costal erosion was first discovered in the 1930’s when houses were built on the beach and …

Aim: The aim of this experiment is to investigate into the effects of the change of carbon dioxide concentrations on the rate of photosynthesis. Prediction: My hypothesis is that as the concentration of carbon dioxide increases the rate of photosynthesis will also increase. Graph showing the effects of carbon dioxide …

Background Information: Oak trees are occasionally covered on one side, with an orange looking substance. This is due to the presence of a simple alga called Trentepholia aurea (Trentepholiaceae). It is made up of filaments of cells that contain high concentrations of carotene, giving it the bright orange colour. Hypothesis: …

Copper has two oxides, Cu2O and CuO. Copper carbonate, CuCO3, decomposes on heating to form one of these oxides and an equation can be written for each possible reaction. Equation 1: 2CuCO3 (s) > Cu2O (s) + 2CO2 (g) + 1/2O2 (g) Equation 2: CuCO3 (s) > CuO (s) + …

INTRODUCTION: Dissolved oxygen (microscopic bubbles of oxygen gas in aqueous solution, DO) is essential for the healthy functioning of all freshwater ecosystems. If more oxygen is consumed than is produced, DO levels decline and some sensitive animals may move away, weaken and even die. Therefore, DO presence in an ecosystem …
