Wind erosion is the main cause. And since it is the desert that wind can pick up tiny sand rock particles that slowly grind against the rock. Over time the erosion will give a jagged rock the smooth features as if it had been submerged in a river for the roughly same period of time.
Slowly, deep underground
The igneous rock gabbro is coarse grained and non-vesicular. Both characteristics show that it is an intrusive igneous rock. Intrusive igneous rocks are formed below Earth's surface and slowly (because they're underground). When rocks are intrusive, they are are non-vesicular (no air pockets) because the air has had the time to escape because of the slow cooling time period. Intrusive rocks are also coarse because crystals had the time to form in the rock during that longer cooling time.
Ps. extrusive igneous rocks form rapidly at Earth's surface and basically have tge opposite characteristics for the opposite reasons (ex: vesicular cause air had little time to escape)
Answer:
(d) Tailed Star
Explanation:
The solar system are planetary bodies made up of the Sun and nine planets which rotate around the sun or have revolution around each other to cause seasons of the year or climatic conditions.
The Morning Star and Evening Star are used to describe Venus, one of the planets. The Pole Star is another member of the solar system, but the Tailed Star is not a member of the solar system.
