This independent study page provides practice for Galicia PAU Geology and Environmental Sciences. Its editorial learning areas include Geology, Earth systems, resources, hazards and environmental evidence. The questions develop subject knowledge and application through worked reasoning, distinctions between competing answers, and practical scenarios. Study the relevant guide before attempting a mixed set, then explain the evidence or calculation that supports each answer. Topics on this exam: Geology, Earth systems, resources, hazards and environmental evidence. The Galicia PAU Geology and Environmental Sciences case studies are 4 cases and about 963 words.
1Reconstruct a geological sequence from stated relationships
In this fictional field exercise, a simplified cross-section contains three sedimentary units labeled A, B and C. The field description states that A was deposited first, B overlies A, and C overlies B,with no overturned beds. All three units were subsequently folded. A granitic intrusion D cuts the folded beds and contains fragments of B.

A fictional surveying worksheet uses a horizontal map scale of 1:50,000. Two points are separated by 6 centimeters on the map, and their elevations are 400 meters and 700 meters. The exercise says to treat that measured separation as horizontal ground distance; it does not ask for a winding walking route. A separate profile uses the same horizontal scale but a vertical scale of 1:5,000.

A fictional class models an aquifer covering 500 square kilometers. Annual recharge is prescribed as 45 millimeters uniformly over that area, while annual pumping is prescribed as 40 cubic hectometers. For this calculation only, the model sets all other boundary inflows, natural discharge, evaporation and exchanges with rivers to zero. These are explicit exercise assumptions rather than a description of any real Spanish aquifer.

Two fictional experimental plots have the same area, soil type and slope. Repeated measurements under the study conditions give annual soil loss rates of 22 tonnes per hectare for a bare treatment and 4 tonnes per hectare for a covered treatment. The exercise asks students to consider applying each measured rate over a hypothetical 45 hectares, solely as an arithmetic scenario. It supplies no sediment delivery ratio, rainfall distribution for future years, reservoir capacity, crop yield or cost data.
