Bright yellow regions are the hottest and emit the most energy out to space. Dark blue and bright white regions, which represent clouds, are much colder and emit the least energy. The Flame by Jackson Pollock, c. For more information, and other works by Pollack, click here.
For example, rock layers show the sequence of geological events, and the presence and amount of radioactive elements in rocks make it possible to determine their ages. Analyses of rock formations and the fossil record are used to establish relative ages.
In an undisturbed column of rock, the youngest rocks are at the top, and the oldest are at the bottom.
Rock layers have sometimes been rearranged by tectonic forces; rearrangements can be seen or inferred, such as from inverted sequences of fossil types. The rock record reveals that events on Earth can be catastrophic, occurring over hours to years, or gradual, occurring over thousands to millions of years.
Records of fossils and other rocks also show past periods of massive extinctions and extensive volcanic activity. Although active geological processes, such as plate tectonics link to ESS2.
B and erosion, have destroyed or altered most of the very early rock record on Earth, some other objects in the solar system, such as asteroids and meteorites, have changed little over billions of years.

The National Academies Press. Major historical events include the formation of mountain chains and ocean basins, volcanic activity, the evolution and extinction of living organisms, periods of massive glaciation, and development of watersheds and rivers.
Because many individual plant and animal species existed during known time periods e. C By the end of grade 2. Some events on Earth occur in cycles, like day and night, and others have a beginning and an end, like a volcanic eruption. Some events, like an earthquake, happen very quickly; others, such as the formation of the Grand Canyon, occur very slowly, over a time period much longer than one can observe.
By the end of grade 5. Earth has changed over time. Understanding how landforms develop, are weathered broken down into smaller piecesand erode get transported elsewhere can help infer the history of the current landscape. Local, regional, and global patterns of rock formations reveal changes over time due to Earth forces, such as earthquakes.
The presence and location of certain fossil types indicate the order in which rock layers were formed. By the end of grade 8. Major historical events include the formation of mountain chains and ocean basins, the evolution and extinction of particular living organisms, volcanic eruptions, periods of massive glaciation, and development of watersheds and rivers through glaciation and water erosion.
Analyses of rock strata and the fossil record provide only relative dates, not an absolute scale.The Moon is an astronomical body that orbits planet Earth and is Earth's only permanent natural monstermanfilm.com is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary).The Moon is after Jupiter's satellite Io the second-densest satellite in the Solar System among those whose densities.
The Moon is about billion years old and is the only natural satellite in our Solar System. The moon formed about 30–50 million years after the Earth formed. The moon came about when a large object hit the Earth and blasted out rocks that all came together and orbited round the Earth.
The Moon is Earth's satellite and orbits the Earth at a distance of about thousand km ( thousand miles) or AU.
The Moon moves into Earth's shadow and direct sunlight can't hit it. The Earth is between the Sun and Moon. This can only happen during Full Moon phases. Dr. Eric Christian. Planet Opposite Earth? Do you think it is possible that there could be another planet making the same orbit as Earth?
This planet would have to be on the exact opposite side of the Sun.
