1. Weathering

Weathering is the alteration of surface rocks by atmospheric agents, such as moisture or air.

1.1 Physical weathering

Physical weathering consists of fragmentation or disintegration of rocks by physical processes, without chemical modification of their composition. Thermal variations cause rock rupture. In cold latitudes or at high altitude, water freezes in cracks and holes in rocks, forming ice wedges that increase fracturing. In warm climates, evaporation can concentrate dissolved salts and form salt crystals, which function much like ice wedges and promote disintegration.

1.2 Chemical weathering

Chemical weathering involves changes in the chemical composition of rocks because of chemical reactions. Examples include:

• Oxidation: oxygen

1. Who are the active geological agents and why are they named so?

Driven by solar energy and gravity, they are called external geological agents.

2. Can badlands originate in an area with abundant vegetation? Why?

No. The vegetation holds the soil with its roots, while stems and leaves slow down water, thus reducing its transport capacity.

3. What is karst relief and how is a column formed?

Karstic reliefs are landscapes caused by the dissolution of limestone or similar rocks. Columns are formed when a stalactite meets a stalagmite.

4. What is the dual effect of relief evolution?

• Arenization: Chemical weathering causes residual gravel to form between blocks.
• Formation of boulders: Granite blocks reduce their volume and acquire rounded forms.

The Origin of the Solar System

Nebular Hypothesis Stages

• Initial Nebula
• Formation of the Accretion Disk
• Formation of Planetesimals
• Formation of Protoplanets

The Origin of the Earth

Stages of Formation

• Collision of planetesimals
• Differentiation of materials by density
• Formation of the crust
• Formation of the atmosphere and hydrosphere

Earth's Internal Heat

• Initial Heat: From the planet's formation and accretion.
• Radioactive Heat: From the decay of radioactive elements.
• Thermal Flow: The process of heat transfer to the surface.

Seismic Waves

• Primary waves (P-waves)
• Secondary waves (S-waves)
• Surface waves

Wave Behavior

As seismic waves travel towards the surface, they are refracted and reflected when they encounter discontinuities between layers.

Introduction to Al-Andalus

In 711, most of the territory of the Iberian Peninsula was conquered by Muslims, initiating a long period of confrontation between Muslims and Christians.

Formation of Muslim Al-Andalus

In 711, Arab troops and North African Berbers crossed the Strait of Gibraltar. They were directed by Tariq and Musa, lieutenant of the Muslim governor of North Africa. Internal conflicts within the Visigothic kingdom in the peninsula made the easy defeat of King Roderic possible. The Muslims exploited this to encourage their expansion across the peninsula.

Areas outside Muslim control were reduced to nuclei of resistance in the Cantabrian mountain range and the Pyrenees. These resistance nuclei became kingdoms that confronted the Muslims...

Understanding Heat and Temperature

Heat is the transfer of energy from hot bodies to cold bodies. It is also called thermal energy. A heat source is an object hot enough to transfer heat to another object that receives it.

Temperature is an indicator of the amount of heat a body has, which is related to the mobility of its particles. The more energy a body stores, the more internal energy its particles will have.

Thermal Equilibrium occurs if a hot body and a cold body are put in contact. The hot body will transmit heat to the cold one until both reach the same temperature.

Primary Sources of Thermal Energy

The main sources of heat include:

• The Sun: The sun provides heat naturally. It is a large ball of fire that gives light and heat to the Earth.

Imperialism: Definitions and Causes

Imperialism: Colonialism is the domain of any form of political, economic, or cultural influence throughout history. It is a system where one nation dominates another under the pretext of ensuring security.

Causes of Imperialism

• Economic: The necessity to invest capital, obtain markets, and control prices for the motherland.
• Strategic: Securing commercial routes.
• Political-Ideological: The desire to seek prestige as a great power.

Forms of Domination

• Colonies
• Protectorates
• White settler dominions

The Monroe Doctrine (1823)

This doctrine pursued the goal of keeping the Americas free from European intervention, allowing the U.S. to intervene economically within the continent.

Judo Penalties and Infractions

Similarly, there exists a system of scores and actions that are valid. There are other penalizations or infractions that are called judoka rules.

Terms and their meaning:

• Hansoku-make: is equivalent to the first action itself, the disqualification of the judoka. The penalized competitor is disqualified with 10 points, which means the opponent receives an ippon to conclude the match.
• Kikoku: penalties with kikoku are given for serious faults, and presuppose the first advertence with a penalization of 7 points. In the same way, one waza-ari is conceded to the opponent.
• Shido: a shido action is penalized with the first warning, which must be noticed by the arbitrator. It is equivalent to 5 points or one yuko conceded

Water Pollution: Effects and Control Methods

Effects: Outbreaks of waterborne diseases such as cholera and typhoid; the destruction of aquatic ecosystems; and eutrophication—a process where nutrient-rich fertilizer runoff causes massive algal blooms that suffocate marine life by stripping oxygen from the water.

Fertilizer Runoff → Algae Bloom → Algae Dies & Decomposes → Oxygen Depletion → Fish Die

Water Pollution Control Strategies

• Setting up Sewage Treatment Plants (STPs) to treat wastewater before it reaches natural rivers.
• Enforcing strict laws on industrial effluent discharge.
• Practicing organic farming to reduce chemical runoff.

Soil pollution refers to the degradation of land quality due to...

Ecological Interactions

• Competition: Chipmunks and squirrels
• Predation: Owls and mice
• Mutualism: Bees and tulips
• Commensalism: Robins and oak trees
• Parasitism: Mosquitoes and dogs

Application: Prairie Ponds and Duck Populations

a) An abiotic factor that influences the number of prairie ponds is precipitation (rain and snowfall). In wet years, increased water collection allows more ponds to form and persist. Conversely, during droughts, ponds shrink or dry up due to reduced water input and higher evaporation rates, causing the number of ponds to fluctuate annually.

b) The hunter’s hypothesis states that if prairie ponds are protected and their numbers increase, the duck population will rise because ducks rely on ponds for food, shelter, and breeding....
