The real estate term âunder contractâ means that a binding agreement exists between a buyer and a seller involving property. The buyer and the seller are in agreement with the terms in the contract. When a property is under contract, the seller may not enter into contract with any other buyer.
Much of the surface of Venus appears to be rather young. The global data set from radar imaging reveals a number of craters consistent with an average Venus surface age of 300 million to 500 million years. There are two continents, which are large regions several kilometers above the average elevation.
The surface of Venus is not easily accessible because of the extremely thick atmosphere (some 90 times that of Earth's) and the 470 Â°C (878 Â°F) surface temperature. Much of what is known about it stems from orbital radar observations, because the surface is permanently obscured in visible wavelengths by cloud cover.
