Answer:
A
Explanation:
A mineral has a specific chemical composition and is occurs naturally. Minerals are also defined by having a crystalline structure. Minerals are not, however, directly associated with organic soils since these types of soils are formed largely by the decomposition of organic matter left from biological processes in ecosystems.
The answer is; movement toward or away from Earth
Stars that move closer to the observer will be percieved as blue in the electromagnetic spectrum while starts moving away from the observer will appear red and orange. This is what is called the Doppler shift effect. This phenomenon is similar to the higher pitch of the siren of an ambulance approaching you and the low pitch of the siren when the ambulance passes you and is moving away from you.
It is most likely B and C
Answer:
Short term global cooling and more rainfall
Explanation:
The eruption of the volcano Mt. Pinatubo in the Philippines managed to propel lot of ash and debris into the atmosphere. The atmosphere is not static, and the air movement manages to disperse these aerosols over much wider area over the planet. Since the aerosols manage to partially block the sunlight, the global temperatures would suddenly drop, thus there will be cooling off of the weather conditions across the planet. Also, the aerosols manage to contribute to more condensation oft he water vapor, and that results in more precipitation, so there has also been more precipitation around the world. The effects have been short term though, as the amount of aerosols propelled into the atmosphere has not been that big so that it can cause long term changes of the climate.
