Energy Transfer/Waves
An kid uses the energy stored in his hand and arm to pull back a slingshot. When they release the slingshot, the ball flies toward a stack of cups. What is the correct energy transformation?
Chemical potential to elastic potential to kinetic
What is always true about Earth's axis?
Always points the same direction.
If it is high tide in Florida and it is currently 2:00PM, what time is the other high tide occurring at?
2:00AM
Give 2 interactions of the hydrosphere and atmosphere.
Examples: Water evaporating into the air. Clouds forming water.
Why is it important to manage how much water we use?
It is a limited resource.
What energy transformation takes place when a plant takes in sun?
light to chemical
What are 3 things that happen in the Summertime? Think about the tilt and how that affects the time of year.
We are tilted towards the Sun which cause more daylight and more direct sunlight causing higher temperatures.
What two moon phases are needed for a Spring tide?
New and Full moon.
Give an interaction of the biosphere and geosphere.
Plants using soil to grow, living things decaying into soil.
What is malnutrition?
Lack of food and clean water
If a student is playing the drums, they create sound waves. What kind of waves are sound waves and how do they move?
Longitudinal, back and forth/side to side
If the Earth is tilted away from the Sun, what season is it? What season would Southern hemisphere be experiencing? What is the season before Winter? What season would the Southern hemisphere be in?
Winter, Summer, Autumn/Fall, Spring
What two moon phases are needed for a Neap tide?
1st quarter and 3rd quarter.
What is the chemical composition of the crust, mantle, outer core, and inner core?
Crust: oxygen, silicon, aluminium
Mantle: iron and magnesium
Cores: Iron and nickel
What are clean energy methods?
Solar and wind
How do transverse waves transfer and how do longitudinal waves transfer? Remember think math terms.
Transverse move perpendicular and longitudinal move parallel.
Winter because they are in the Southern Hemisphere and are experiencing the opposite season of the United States.
What causes a high tide and what causes a low tide?
High tides are caused when the moon is align. For example, the side of the Earth that is closest and furthest away are high tides. Low tides happen when the moon is no aligned with that side of the Earth.
Why is the crust the outermost layer?
It is least dense.
Farmers rely on groundwater to grow crops. Groundwater can become scarce if overused. Why is it important to manage our groundwater based on malnutrition?
Without groundwater, we cannot grow our crops which leads to lack of food or malnutrition.
What is the height of the wave called?
What is the distance between crests called?
Transverse waves move how?
Amplitude, wavelength, up and down and perpendicular.
What is a solstice? What is an equinox?
A solstice is when we have longer days or nights. An equinox is equal amounts of day and night.
Which type of tide is best to go seashell hunting? (Think both kinds of tides, normal and special) Tell me why.
Low spring tide because that is the lowest tide and we have more beach to search.
Tell me how each rock in the rock cycle is formed.
Sedimentary: weathering, erosion, deposition, compaction, cementation
Metamorphic: heat and pressure
Igneous: melting and cooling
What is global energy poverty and what countries tend to have this issue?
Lack of energy and or clean energy. Africa has this issue.
