What minerals are found in igneous rocks? What is extrusive igneous rock? Which rock consists of mafic minerals and has a phaneritic texture? What rock makes the best aquifer? What rocks are in the lithosphere? What kind of rock is phyllite?
Researchers from the U.S. space agency NASA are currently trying to find out what kind of plants could grow in the red soil on Mars(火星). They hope that astronauts will be able to start growing their own food on the red planet. The journey to Mars could take up to two-and-a-half...
Lichens (地衣) are difficult to see.They don't move.They often mix into the living place.You might not even recognize one if you are looking right at it. Lichens live on rocks,branches,houses,even metal street signs.You can find these colourful organisms (有机体) almost everywhere-from de...

Earth, deltas are habitable environments that can preserve evidence for life in their rocks and minerals," Williams adds. "We hope to return samples from the delta front that can tell us more about the potential for biosignatures to be preserved in these types of rocks on Mars," she said...
In rock units where the sections are less complete, the time frame is longer-even as much as a million years. In marine rocks (rocks formed in seas or oceans) the record is often more complete. It is here that the earliest and some of the strongest evidence for an extraterrestrial (...
The probability of winning is tiny. So in the game of planetary formation, forming a solar system with our Earth is like winning the lottery.获胜的可能性很小。所以在行星形成的游戏中，太阳系中诞生了地球就像中了彩票一样。Scientists are only now fitting together all the various chapters of this...
If you then attempt to roll a marble around the edge of the trampoline, the marble would spiral inward toward the body, pulled in much the same way that the gravity of a planet pulls at rocks in space. In the decades since Einstein published his theories, scientists have observed countless...
These samples were taken at different locations, which allowed scientists to study different types of lunar rocks.Answer and Explanation: A lunar meteorite is a meteorite that originated from rocks on the Moon. As the Moon has been subjected to many impacts over billions of years, A......
