what are some of the environmental problems found?
Global climate change.
Geology
 Ice cores and sediment cores are used to for paleoclimate reconstructions, which tell geologists about past and present temperature, precipitation, and sea level across the globe. These datasets are our primary source of information on global climate change outside of instrumental data.
match the type of play with the age of occurrence UNANSWERABLE what is paleontology? The scientific study of life that existed prior to, and sometimes including, the start of the Holocene Epoch. how is the study done? It includes the study of fossils to classify organisms and study interactions with each other and their environments. what are the other branches of science related to it? Biology and geology. what is observed through geochemical technique? These observations may help to deduce the global level of biological activity at a certain period, or the affinity of certain fossils. what does the latter branch of science deal with? It is an Earth science concerned with the solid Earth.

Geology [SEP] Hydrology and environmental issues
Geology and geologic principles can be applied to various environmental problems such as stream restoration, the restoration of brownfields, and the understanding of the interaction between natural habitat and the geologic environment. Groundwater hydrology, or hydrogeology, is used to locate groundwater, which can often provide a ready supply of uncontaminated water and is especially important in arid regions, and to monitor the spread of contaminants in groundwater wells. Geologists also obtain data through stratigraphy, boreholes, core samples, and ice cores. Ice cores and sediment cores are used to for paleoclimate reconstructions, which tell geologists about past and present temperature, precipitation, and sea level across the globe.
