When strong solar winds are displaced poleward by our magnetic fields, we get: intense auroral displays. The oldest rocks on our crust are radioactively dated at about: four billion years old.
What is the best description of the Earth’s rotation over its entire history Group of answer choices?
What is the best description of the Earth’s rotation over its entire history? It has slowed down very gradually at about . 0015 seconds per century. At what phase are the tides least noticeable?
Which layer of the Earth is the most unique of the terrestrial planets?
Earth is unique among the planets in that its outer surface — the lithosphere — is divided into several rigid plates. These plates move. In some cases they move toward each other, in some cases away from each other, and in some cases, the edges move alongside each other.
Which are places on Earth where convection is operating on a grand scale creating conditions important to life on Earth?
Which are places on Earth where convection is operating on a grand scale, creating conditions important to life on Earth? in the troposphere, such as a summer thunderstorm; at the thermal vents in the rift valleys; in the mantle; in hot springs like Old Faithful; All of the above are good examples.
In what scenario is the blue component of incoming sunlight is scattered much more than any other color component quizlet?
In what scenario is the blue component of incoming sunlight is scattered much more than any other color component? seismic wave data.
Why don’t we feel the rotation of the earth?
Bottom line: We don’t feel Earth rotating on its axis because Earth spins steadily – and moves at a constant rate in orbit around the sun – carrying you as a passenger right along with it.
In what ways is Earth unique among the terrestrial planets?
The Earth is unique among the Terrestrial planets because it has liquid water on its surface and life that is aware living on it. The density of the surface rocks is lower than the overall density of the Earth. Therefore, the more dense rocks must be in the interior.
Who made Earth?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
What are the main differences of the Earth’s atmosphere when compared to other terrestrial planets in our solar system Mercury Venus and Mars )?
Explanation: The main difference between the Earth’s atmosphere and the one of other planets (such as Venus and Mars) is that about 21% of it is composed by oxygen. Oxygen is a key element to sustain any complex life form on the planet.
What is the function of the Earth’s core in sustaining convection currents in the mantle?
The heat released from the core helps drive mantle convection, which, in turn, leads to surface features such as volcanism and plate tectonics.
How is it possible that convection happens in the Earth despite the mostly solid asthenosphere?
the earths core heats the mantles rocks toward the top, when the rocks cool they fall back down, creating a rise and fall which is convection currents, Inner core is solid rock and the outer core is liquid.
What problem does adaptive optics correct quizlet?
What problem is adaptive optics designed to correct? provide better angular resolution than orange light. Which of the following greatly improves the angular resolution of radio maps? they record much more light in a given exposure time.
Which parts of the Sun’s radiation are responsible for heating Earth surface?
[more on electromagnetic radiation] It is infrared radiation that produce the warm feeling on our bodies. Most of the solar radiation is absorbed by the atmosphere and much of what reaches the earth’s surface is radiated back into the atmosphere to become heat energy.
What is the deepest geologists have drilled into Earth?
The Kola Superdeep Borehole was just 9 inches in diameter, but at 40,230 feet (12,262 meters) reigns as the deepest hole. It took almost 20 years to reach that 7.5-mile depth—only half the distance or less to the mantle.
What happens when two tectonic plates collide quizlet?
a collision between two continental plates crunches and folds the rock at the boundary, lifting it up and leading to the formation of mountains and mountain ranges.
