"Understanding whether convection is taking place offers clues into how Mars has evolved into its current state over billions of years," he said. He added that there are two competing hypotheses to explain why the southern hemisphere of Mars has a thicker crust and is five to six kilometers ...
“Building a complete city from scratch, evenin a small size like this, is a unique chance to develop future technologies. With people, buildings and vehicles all connected and communicating with each other through sensors, we will be able to test connected AI technology in both the virtual(虚...
Weight at the Surface of the Earth The gravitational force at the surface of the Earth is equal to the weight. This force pulls us down to the surface of the Earth whose magnitude is the product of the mass of the objectmand acceleration due to gravity...
How did scientists learn what lies deep inside the earth? How do scientists know what's in the different layers? How do scientists know there is convection in the mantle? How do seismologists locate earthquakes? How does an archaeologist read stratigraphy?
The warm, shallow waters of the sub-tropical West Pacific might be a draw for holidaymakers, but they’re also the base ingredients for a high-energy summer cocktail. Just add heat, sub-tropical humidity, a bit of convection and stir it up with drag of the Earth’s rotatio...
Another effect of gravity is that it causes convection currents to form in flames, which leads to unsteady flames. This makes the study of combustion very difficult. However, in microgravity, simple, steady, slow-moving flames result; these types of flames make it easier to study the ...

As climate change stokes larger and more intense wildfires, firestorms are likely to become more common. Here’s why they occur and what makes them so dangerous.
Heat travels by conduction through the solid walls and roof of your home. On the outside, the outer walls and the roof tiles are hotter than the atmosphere around them, so the cold air near to them heats up and flows away by convection. Your house may seem like a big complex space wi...
How is electromagnetic radiation created? How is energy transferred during convection? Why does the sun emit neutrinos? What causes the Sun's magnetic field? Is there an electromagnetic force between Earth and Sun? How did the universe form?
