Carbon Dioxide 3 of 34 When Earth was first formed it's atmosphere was similar to which planets? Venus and Mars 4 of 34 Earth's early atmosphere was similar to Venus and Mars, what do their atmosphere's consist of? Carbon Dioxide with little or no Oxygen 5 of 34 What produced the gases present in Earth's early atmophere? Volcanoes 6 of 34 Which gases were present in Earth's early atmosphere? Carbon Dioxide, Water vapour and Nitrogen with small amounts of Methane and Ammonia 7 of 34 By what process do algae and plant's produce Oxygen? Photosynthesis 8 of 34 Write the word equation for Photosynthesis? Carbon Dioxide + Water = Oxygen + Glucose 9 of 34 How did the worlds Oceans form? The Earth's temperature cooled, causing water vapour in the air to condense 10 of 34 Why have theories about Earth's early atmosphere developed and changed over time? Evidence is limited, so we are unsure 11 of 34 How did the Oceans reduce atmospheric levels of Carbon Dioxide in Earth's early atmosphere? Carbon Dioxide dissolved in the Oceans 12 of 34 How did algae and plants reduce levels of Carbon Dioxide in Earth's early atmosphere? By photosynthesis 13 of 34 What was formed when shells of organisms made using dissolved Carbon Dioxide, fell to the bottom of the Ocean and were covered and compressed? Sedimentary rock 14 of 34 What was formed when plants grew millions of years ago, died and were trapped and compressed under rocks? Coal 15 of 34 What was formed when Plankton that lived in the Ocean millions of years ago, died and were trapped and compressed under rocks? Crude Oil and Natural Gas 16 of 34 Name three Greenhouse Gases? Water Vapour, Carbon Dioxide and Methane 17 of 34 Describe the wavelength of radiation thatcomes from the Sun? Short Wave 18 of 34 Describe the wavelength of radiation that is reflected back off the Earth? Long Wave 19 of 34 What happens to Long Wave radiation that is reflected from the Earth's atmosphere? It is absorbed by the Greenhouse Gases 20 of 34 What is the namee given to the process that warms the surface of the Earth? The Greenhouse Effect 21 of 34 What Human Activites increase Carbon Dioxide levels? Deforestation and burning of Fossil Fuels 22 of 34 What Human Activites increase Methane levels? Farming Animals and Landfill 23 of 34 What is the name given to the increasing tempertaure of the Earth? Climate Change 24 of 34 Name an effect of Climate Change? Inceased Flooding, changes in Rainfall patterns, frequancy of Storms, amount of Water in a habitat ect ... 25 of 34 What is the name given to the total amount of Carbon Dioxide and other Greenhouse Gases emitted over a full lifecycle of a product, service or event? Carbon Footprint 26 of 34 What is produced from the complete combustion of a Hydrocarbon Fuel? Carbon Dioxide and Water 27 of 34 Which gas is produced when Fuels are burned and contain the impurity Sulfur? Sulfur Dioxide 28 of 34 Which products could be produced from the incomplete combustion of a Hydrocarbon Fuel? Carbon Dioxide, Water, Carbon Monoxide and Carbon Particles 29 of 34 Which Gases are produced when Nitrogen and Oxygen react in the very high Temperatures of a Car Engine? Oxides of Nitrogen 30 of 34 What are the Effects of Carbon Monoxide? A toxic Gas 31 of 34 What are the Effects of Sulfur Dioxide? Causes Respiratory Problems and Acid Rain 32 of 34 What are the Effects of Oxides of Nitrogen? Causes Respiratory Problems and Acid Rain 33 of 34 What are the Effects of Particulates of Fuels? Causes Global Dimming and Health Problems for Humans 34 of 34
