The notation Rr represents heterozygous alleles. This is because the alleles are defined as the variants of a given gene and, as the notation has two different alleles it is heterozygous in nature.The two alleles in the notation are R and r.The allele R is the dominant allele and r is the recessive allele. Since the notation shows that both of these alleles are defining the genotype it is a heterozygous condition.
volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
