Webtwo reasons for thinking the earth's core is liquid: 1) s-waves were blocked by earth's interior: geologists believe that they were absorbed by a liquid core at Earth's center and that P-waves are "refracted" at the core boundary 2) presence of magnetic field (dynamo theory) What does differentiation tell us about the Earth's history? WebWhat was Earth like, 4.5 Billion years ago? Volcanoes were erupting, there were no oceans, and volcanic gases formed the Earth's atmosphere. How did Earth's oceans form? When Earth cooled enough for water to condense, rain began to fall and filled the deeper parts of Earth's surface until the first oceans formed. Panthalassa

WebEARTH: - Has plate tectonics - has many craters w/ a diameter about 10 meters BOTH: - Has evidence of past volcanic activity - Surface includes mountains and rolling plains Venus and Earth's Moon are quite different. Venus is much larger, more massive, and has an atmosphere. However, Venus and the Moon share some similar surface features. WebEarth's atmosphere is much different in composition than Venus's because a. water is a liquid on the surface of Earth b. the two planets' secondary atmospheres formed differently c. Earth has had fewer impacts d. Earth retained more of its primary atmosphere ANSWER A WATER IS A LIQUID ON THE SURFACE OF EARTH
WebAs understood by geoscience, the Earth is 4.6 billion years old. - this number is based on the age of the oldest rocks on Earth (fossils, sediment deposition, Earth cooling from a molten state, radioactive decay, etc.) - between 1800-1850, geologists started to believe the Earth was much older than postulated. Kelvin's Age of the Earth. WebHow earth and planets were formed: steps of the differentiation process in order from the initial stage to the final stage. -initial stage->final stage Intense bombardment and radioactivity Heating and melting of rock Sinking of heavier metals toward center floating of lighter rocks toward the surface Cooling and solidification of rock layers
