Module 3 Waves and the Electromagnetic Spectrum Topic: Waves 1. What is a wave? A wave is vibration that travels and all waves are created by something vibrating. Waves transport energy but do not transport mass. 2. Describe the following terms associated with waves: a. amplitude height of wave b. wavelength length of a wave c. frequency number of waves per second (Hz) d. period how long a wave lasts when it arrives at a fixed point (measured in seconds) 3. What are radio waves

Earthquakes I Earth’s composition Earth is a dense, stratified planet with many layers: core (inner and outer), mantle and crust Inner core: most dense material, solid iron and nickel Outer core: second most dense, liquid, iron and nickel Mantle: composed of oxygen, silicon, magnesium, aluminum Crust: composed of sodium and potassium rich silicate rocks Upper 100-350 km of upper mantle makes up asthenosphere: fluid layer due to heating from core Plate tectonics Earth’s uppermost layer, the

due to dyeing process inefficiencies. Colour itself could be very pernicious to the receiving water courses not only for aesthetic reasons and toxicity towards many aquatic organisms, but also because coloured compounds reduce water transparency, which, in turn, affects photosynthetic activity, thus causing severe damage to the ecosystems. (Nermeen and

resilience is the capacity of an ecosystem to respond to a perturbation or disturbanceby resisting damage and recovering quickly. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation and the introduction of exotic plant or animal species. Disturbances of sufficient magnitudeor duration can profoundly affect an ecosystem and may force an ecosystem to reach a threshold beyond which
