Prerequisites

Basic notions of Physics and Chemistry are recommended as well as a good level of written comprehension of the English language.

 

Objectives and Contextualisation

Basic understanding of the fundamental concepts about:

  • The origin and evolution of the Universe, the formation of the Earth and the evolution of the early Earth.
  • The solid Earth and its internal structure.
  • The Time variable in Geology.
  • Earth Dynamics and Plate Tectonics.
  • Atmosphere and Hydrosphere.
  • Interaction between Atmosphere, Hydrosphere and solid Earth. Climatic systems.
  • The search for energy and sustainable development.

Competences

  • Display understanding of the fundamental principles of geology and the ability to identify the basic types of minerals, rocks and structures.
  • Display understanding of the size of the space and time dimensions of Earth processes, on different scales.
  • Recognise, depict and reconstruct tectonic structures and the processes that generate them and relate types of rocks and structures to geodynamic environments.

Learning Outcomes

  1. Discern the basic relationships between geology and the problems of environmental change.

Methodology

Theory:

  • Magistral classes

Seminars:

  • Seismology I. Seismic Waves. Epicenter and magnitude of earthquakes. Calibration of travel-time curves and evaluation of epicenter and magnitude of an earthquakes.
  • Seismology II. Spatial and temporal distribution of seismicity on Earth. Information and databases. Seismic software. Earthquakes related to volcanic activity: the example of the El Hierro eruption. Evolution of seismicity during a major earthquake.
  • Geological time I: Examples for understanding of the spatial and temporal dimension of Earth's History.
  • Geologic time II: Making geological time scales using the main events of Earth's History.
  • Carbon cycle on Earth: Models of the recent C cycle.
  • Additional Seminars  / alternative exercises: Characterization of plate boundaries using structures and volcanism, Plate Tectonics, paleogeography. Calculations of atmospheric and hydrosphere parameters. El Niño. 

* Teachers can set the obligatory (or the optional) presentation of a dossier - exercise related to each of the seminars. This work can be evaluated in the manner determined by the teacher (assigning a grade, using this grade to refine / recalculate the final grade or other uses at teacher’s criteria.

 Theachers will allocate 15 minutes of a class to allow the students to answer to a set of questions regarding the evaluation of the academic performance.

Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment

Continuous assessement (CE):

 2 exams (which will include the contents of the theory as well as those of seminars). Each test will score 10 pt.

 1st exam: Theory  + Seminars *. Test questions of the theory topics 1st part (will be communicated) ± test questions about the associated seminars ± short questions about the theory or seminars) = 40% total CE

 2nd exam: Theory + Seminars *. Test questions of the theory topics 2nd part (will be communicated) ± test questions about the associated seminars ±short answer questions about the theory or seminars) = 40% total CE

Works / Dossiers on the seminars carried out or other exercises proposed by the professors. You must submit all items that professors stablish as compulsory. Grading will be: Very Good-10, Good-7, Normal-5, Incorrect-3, Very incorrect or not submitted-0. The average grade is then calculated, and its weight will be 0.2. If there are two dossiers or papers not submitted, this part of the grading (20%) will be lost. The dossiers or works must be delivered on the due dates. The non-submission on due dates implies a non-submitted mark and will not be recoverable in any case after the date fixed for submission, which in any case will be prior to the date of the second exam.

Continuous evaluation score (CE score) = score on 1st theory exam x 0.4 + score on 2n theory exam x 0.4 + score on Dossiers / works x 0.2

To succesfully pass the subject by continuous evaluation the CE score must be equal or greater than 5 and the grade of each exam will have to be greater than 3. Grades less than 3 in an exam prevent to calculate the CE grade and the student must do the corresponding part again on the final exam.

Final Exam:

 The final exam will consist of two parts:

1: Recovery of the first exam (theoryand seminars)

2: Recovery of the second exam (theory and seminars).

In the event that a grade lower than that obtained in the corresponding partial one is obtained; the arithmetic mean of the two grades will be made and this will become the final grade in this part (theory).

If, in any of the two theory exams the grade remains below 3, the final grade will be failing. In this last case if the grade average is greater than 5 the numerical grade will be reduced to 4.9 and it will be also failing).

Students with a grade of fail or non presented to any of the exams must present to these parts of the final exam and do not have to notify the teacher.

Students who wish to improve the grades of one or two parts in the final exam must notify in advance what is / are those parts (that is, first exam, second exam or both). The teacher will implement a list with a registration deadline for this final exam. If the teacher does not receive an alert from the student within the stipulated limit, the student can not present to final exam and will lose the right to improve the grades of the exam/s.

FINAL GRADE:

The formula for calculating the final grade will also be:

Final Qualification = (score 1st exam Test theory + Seminars X 0.4) + (scopre 2nd exam Test theory + Seminars x 0.4) + Score works/dossiers x 0.2

If the final score is ≥ 4.8 and you have submitted the work/exercise/compulsory dossiers (or optional substitutes, if appropriate) (not more than two unsubmitted) and if the qualification of these works/exercises is ≥ 5 you can increase the grade to 5 and approve the subject. In no case may the subject be exceeded with notes < 4.8 or (5 > Note 4.8) with two compulsory works/exercises/dossiers not presented.
