What are convection currents in the Earth's mantle? Heat and Density: Hot particles are less dense than cold particles. This applies to air, water, and rock in the mantle of the Earth. Since warmed particles move faster, there is more space between them. The wider space between particles ...
Conclusions: 1. What you observed is called a convection current. What caused the convection current to begin?in others?)
Convection currents are evident in the sun. The granules seen in the sun's photosphere are the tops of convection cells. In the case of the sun and otherstars, the fluid is plasma rather than a liquid orgas.
much less that of a planet many solar systems away, Luger said. We don't know what would happen if Earth were supersized or closer to the sun. But, so far, it seems very fortunate that we aren't living on a planet
The geologic processes of the earth may seem to be happening very slowly, but they still affect our everyday lives. For example, the different types of boundaries formed by tectonic plates cause different geologic events such as volcanoes and earthquakes. ...
Explain why the length of a day increases. If there were a great migration of people toward the equator, how would this affect the length of the day? What will happen to the length of the day when the polar ice caps of earth melt? What is the difference between a supergranule ...
Did you happen to notice any patterns in the materials that make up the sun? Hydrogen and helium are the first two elements on the periodic table: the simplest and lightest. The heavier and more complex an element, the less of it we find in the sun. ...
Energy causes things to happen around us. Look out the window. During the day, the sun gives out light and heat energy. At night, street lamps use electrical energy to light our way. When a car drives by, it is being powered by gasoline, a type of stored energy. The food we eat ...
Reply to a letter by 18 scientific organizations to the U.S.A. Senate on climate legislation. How could it happen that more than a dozen of the most prestigious scientific associations signed and submitted this letter on �climate change� without having ensured that the used terminology is...
“elastic rebound theory”, based on his studies of the 1906 San Fransisco earthquake. This theory, which stated that earthquakes occur when accumulated energy is released along a fault line, was the first scientific explanation for why earthquakes happen, and remains the foundation for modern ...
