Astro 101 Sbcc T2 SK – Flashcards

It is much smaller in mass

escape velocity (determined by mass and radius) atmospheric composition temperature

Differentiation

Convection from the hot interior

The moon's core contains little if any molten iron

Mars has much thicker crust than Earth

Volcanism

trapping infrared radiation from escaping into space

The Appalachians are much older and have been smoothed by erosion.

the lava plains of the lunar lowlands.

using radar maps made from Earth. using radar maps made from satellites orbiting Venus. using spacecraft that have landed on the surface of Venus.

They formed elsewhere and were captured at a later time.

The large impact hypothesis

Mercury

Mars' rotational axis is tilted relative to its orbit like the Earth's.

Valles Marineris

Olympus Mons

Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune

Inner Core: is the hottest but since the pressure is so great it makes it solid made out of nickel and iron Outer Core: Is liquid iron and and nickel because the pressure is less intense Mantle: inner is a thick liquid to the outer part being hard rock. Crust: hard rock.

Dynamo effect: Earth's core being liquid metal. Convection currents sir the molten liquid which is a good conductor of electricity. Overall it protects the atmosphere

Measures through liquid

Can travel along the surface of liquid but not through it. This can measure the liquid core by observing where the waves can get though and where they do not

gases of hydrogen and methane captured from the nebula

The air breathed today. Where gases were made from the resources within the planet. Once cooled enough, oceans formed, and carbon dioxide dissolved in the water

separation of materials according to density

Jupiter's largest moon about the size of mercury and largest in the solar system. Low density half rock & ice rocky interiors and low density exteriors old because of being heavily cratered and dark 3rd moon in order has aurora's

4th moon in order Low density half rock & ice rocky interiors and low density exteriors old because of being heavily cratered and dark

size of earth's moon 3 mile deep ocean under the ice which makes the old surfaces new surfaces when a meteorite hits cold, icy.

most dense tidal heating causes volcanic activity (most vocalically active moon) and it heats the interior 1st in order albedo

has the second most magnetic field. largest planet in our solar system Radiates more energy than it absorbs. poles and equator are the same temperature Mostly made out of liquid metallic hydrogen which cause the magnetic field

The minimum distance between a planet and a moon that can hold itself together by its own gravity 2.4 radius

brighter and hotter because of rising gas forms clouds high in the atmosphere where sunlight is stronger and reflected back outside viewers

cooler and darker than zone.

The natural lights near the poles where the magnetic sphere is disturbed by solar wind

gas and dust revolves around the sun counterclockwise. dust and gas particles transitions to planetesimals by condensation and accretion then to protoplanets by gravity. Finally gravity sweeped everything out of its orbit to become a sphere orbiting the sun called a planet

Are planets found outside our solar system

Detected planets by seeing when they went in front of star to cause a shadow, duh! detected 1000 more planets by Kepler's mission! YES

Doppler affect saw the hot Jupiters.

directly visualizing through a telescope. Bad, very bad method.

Mostly made out of hydrogen and helium has belts and zones 62 moons

Titan is largest of Saturn's moons Has traces of water
