SCIENCE FINAL Flashcards
study these until the final to practice- on the weekend of 5/26/25 use paper flashcards (15 cards)
What process changes sediment into sedimentary rock?
Compaction and cementation.
What type of rock forms when existing rock is changed by heat and pressure?
Metamorphic rock.
How can igneous rock turn into sediment?
Through weathering and erosion.
Can a metamorphic rock turn directly into an igneous rock? How?
Yes, if it melts into magma and then cools.
What causes the phases of the Moon?
The Moon’s position relative to the Earth and Sun; we see different portions of its lit half.
During which moon phase does a solar eclipse occur?
New moon.
What moon phase is seen when the entire side facing Earth is lit?
Full moon.
What’s the difference between a solar eclipse and a lunar eclipse?
A solar eclipse happens when the Moon blocks the Sun; a lunar eclipse happens when Earth’s shadow covers the Moon.
What is the main difference between potential and kinetic energy?
Potential energy is stored; kinetic energy is energy of motion.
If you lift a ball higher, what happens to its potential energy?
It increases.
What happens to particles in a solid when heat energy is added?
They move faster and spread apart; the solid may become a liquid.
What kind of wave needs a medium to travel through: sound or light?
Sound.
What part of a wave is the highest point?
Crest.
If a wave has a higher frequency, what does that mean about the energy it carries?
It carries more energy.
What happens to light when it moves from air into water?
It bends—this is called refraction.
