Question Answer
what is the charge for electrons negative
what is the charge for neutrons neutral
what is the charge for protons positive
what is an ion positive charged atom
what is static electricity build up of electric charge on a surface
difference between static and current electricity static is the build up of electric charge and current electricity is from a battery
how to measure voltage to measure voltage you use a volt metre
units of measurement ohms, amps, current, voltage
parallel globes how do they work parallel globes don't share voltage but instead have equal amount of voltage in their globes
series globes how do they work series globes share voltage which makes each globe dimmer.
transformers transformers are devices that use induction to transform high a.c voltage to low vice, versa.
resistors resistor is an electrical component that limits the flow of electric current in a circuit
insulators a material that does not easily allow heat, sound, light or electricity to go though it.
conductors electricity travelles easily through
what is an amnetre measures the electric current
what is dc direct current. flows in one direction
what is ac alternating current. chanages direction periodically.
what is electromagnetism interaction of electric currents or fields in magentic fields.
what is continental drift continental drift is the theory that the continents are always moving.
what is pangea its a super continent that existed over 220million years ago
who developed the idea of continental drift Alfred Wegner
what is the evidence for continental drift when all the continents are put together like a jigsaw they all fit together like a super continent
4 layers of the earth crustmantelouter core inner core
types of tectonic plates oceanic continental
what causes plates to move convection current beneath the plates
fault lines a line on a rock or a surface or the ground that traces the geological fault
collision zones when the tectonic plates are meeting at a convergent boundary both bearing continental lithosphere
Subduction Zone: A region of the Earth's crust where tectonic plates meet.
Continental Rifting: The belt or zone of the continental lithosphere where the extensional deformation (rifting) is occurring
Who discovered Sea Floor Spreading Harry Hess.
What is Seafloor Spreading? A process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
Where are Earthquakes most likely to occur? Earthquakes occur both along plate edges and along faults. Most earthquakes occur along the edge of the oceanic and continental plates.
What causes Tsunamis tsunamis can occur from an earthquake, an underwater landslide, a volcanic eruption or a large meteorite strike.
What is a Hot Spot? Hot spots are places within the mantle where rocks melt to generate magma.
What are the major processes of the Water Cycle? evaporation, transpiration, condensation, precipitation, and runoff.
Where is carbon found on Earth? Carbon is found in the atmosphere, in the soil, and it's in rocks, and the ocean.
What are the major processes of the Carbon Cycle? Photosynthesis, Respiration, Combustion, Decomposition
How is Carbon stored on Earth Living organisms, deep ocean sinks, fossil fuels.
What is a Carbon Sink? When ocean water in these areas gets very cold, sea ice forms. The surrounding sea water gets saltier, increases in density and sinks.
The role of Decomposers in the Carbon Cycle. They break down the remains of dead plants and animals and, in doing so, release carbon dioxide through respiration.
What is the Greenhouse Effect & how does it work? The greenhouse effect is a natural process that warms the Earth's surface.
Greenhouse Gases water vapour, carbon dioxide, methane, nitrous oxide, ozone
What is the Enhanced Greenhouse Effect? The impact on the climate from the additional heat retained due to the increased amounts of carbon dioxide and other greenhouse gases that humans have released into the earth's atmosphere.
What are some of the outcomes of the Enhanced Greenhouse Effect? Climate Change.Coral bleaching of the great barrier reef.Floods, bushfires and storms.Seawater levels rising.
