Meteors and Meteorites
These are chunks of solid material that survive passing through the Earth's atmosphere and are found on the Earth's surface.
meteorites
Which planet is the most geologically active after Earth?
Venus
The telescope in space that allowed astronomers to find exoplanets making measurements of changes in a star’s brightness.
Kepler
This is a solid material that creates a fiery tail as it burns up in the earth’s atmosphere (shooting star).
meteor
Which planet has the tallest mountains?
Mars
This is the first technique that allowed astronomers to find exoplanets.
The Doppler Effect/ Changes in radial velocity of a star
This is caused when a periodic comet leaves its dusty debris behind in its orbit, the Earth can intercept this debris which burns up in its atmosphere.
meteor shower
What is a cause of geological activity on terrestrial planets?
plate tectonics (Earth), internal heat of a planet (due to radioactive decay or heat from planet formation)
What was unique about the Murchison meteorite from Australia?
It contains organic materials, such as amino acids.
This occurs some years some meteor showers, such as the Leonids, feature many more meteors than at other times due to the dust freed from some comets not being evenly distributed along its orbit.
meteor storm
This is the vast, rotating cloud of vapor and dust from which the solar system formed.
solar nebula
What method did scientists use to estimate the age of meteors?
radioactive dating
How old do scientists think meteors are?
4.5 billion years
What does the Bible say about how the universe was created?
God created the solar system in 6 days. The sun and moon were created to give light to the Earth. God created animals and people.
How large is a typical meteor?
about 1 gram, no larger than a pea
