Witryna12 maj 2024 · Loose sand, blown away from source regions by winds, is transported across Mars's surface into sand sheets and dunes and accumulates within topographic sinks. In the absence of plate tectonics, impact craters constitute a dominant sink for windblown sediments on Mars today.

While it is not the rule to find impact-melt ponds in 5-km lunar craters, such deposits are hardly a rarity. earth song michael jackson text

WitrynaSand is fragile: If you set down a ball, no matter how gingerly or how roughly, the sand can barely support the ball’s weight; one slight tap and the ball digs in deeper. At the same time, sand can be very strong: If you drop the ball from some height, the sand can stop it quickly, forming a shallow crater in the process; a higher drop earth song michael jackson paroles
