Understanding Climate Fundamentals

Weather conditions at a given location are calculated using statistics over a minimum of 30 years. These calculations take into account temperature, humidity, pressure, winds, and precipitation.

Weather: Short-Term Variations

This refers to variations in temperature, atmospheric pressure, and precipitation in a region that exist at a given time.

Zonda Wind

This is a hot, dry wind (around 22°C) that descends at high speed from the Andean slopes in winter over the provinces of Mendoza and San Juan, significantly altering winter temperatures in the area of influence. It originates from the Pacific Ocean anticyclone.

Orographic Rainfall

Occurs when damp winds hit the mountains, rise, cool, and water vapor in clouds...

Sound Changes in Historical Linguistics

Assimilation

Assimilation occurs when a sound becomes more similar to an adjacent sound in voicing, manner, or place of articulation. The direction of assimilation can be:

• Regressive: For example, Old English wifman becomes wimman.
• Progressive: For example, Germanic *wulno becomes wullo and then Old English wull.

The extent of assimilation can be:

• Total: For example, Old English wifman.
• Partial: For example, Latin in + premiere becomes impremiere.

Assimilation can also be relative to the environment, such as:

• Immediate: For example, English attain.

Palatalization

Palatalization is a process in which a front vowel causes a sound to move forward or backward to become more palatal in articulation. For example:

• Old English

Factors Determining Erosion Effectiveness

The energy of a geological agent: A great river with steep and erosive capacity has more than one of lower flow and calmer course. A large glacier erodes more than a smaller one.

The strength of rocks: Some rocks such as clay, limestone, and sandstone are easily eroded, while granite and gneiss are hard rocks where erosion progresses slowly.

Related Geological Agents

Wild Water

• Water with no fixed course, from rains.

Rivers

• Permanent water courses.

Torrents

• Located in mountains, always with water.

Glaciers

• Rivers of ice in polar regions or high mountains.

Landform Examples

• Wild-water gully
• River valley in V
• Valley glacier-torrents
• Sea cliff
• Glacier valley

River Characteristics

Upper Course

• Runs through high mountain areas.

Heavy Industry

In heavy industry, raw materials are transformed into semi-finished products that are then used in other industries. Heavy industries require large capital investments and occupy vast areas near energy sources and raw materials.

Types of Heavy Industry

• Heavy Chemical Industry

  It uses many different raw materials (e.g., coal, hydrocarbons, sulfur, salts) to produce essential materials for other industries (e.g., fuels, fertilizers, acids, explosives).

• Metallurgy

  It transforms non-ferrous minerals into metals (e.g., aluminum and copper) and semi-finished products (e.g., laminates, shaped, and molten metals) for other industries.

• Ferrous Metallurgy

  It transforms iron into steel to make machinery, rails, and other elements required by many

HUMAN IMPACT

Acidic rain: It is a broad term that includes any form of precipitation with acidic components and results when dioxide (So2) and nitrogen oxides (NO) are emitted into the atmosphere and transported by wind and air currents. Acid rain is caused by the burning of fossil fuels to generate electricity, the chemical releases of vehicles and from manufacturing. There are two forms of acid rain: dry deposition which is crust in a sheltered area and wet depositions that are raindrops of sulphurous acid. Acid rain can be very harmful to the environment because it takes away minerals from the leaves and soil and without them plants cannot grow properly. Even if this rain doesn’t fall straight into lakes it can get there through rivers...

Climate and Vegetation in Spain

General Characteristics

• Annual Average Temperatures: Temperatures increase from north to south. They are lower in the peninsular interior, where a greater temperature range is also observed compared to the coast.
• Rainfall: Precipitation has a strong seasonal variation, except in the northern peninsula. It decreases from north to south, from west to east, and from the coast inland.

Types of Climate

Oceanic Climate

This climate is characterized by mild temperatures and abundant rainfall throughout the year.

Mediterranean Climate

Its main characteristic is a marked dry season in summer. There are several varieties:

• Coastal Mediterranean Climate

  Features mild temperatures and moderate rainfall.

• Inland Mediterranean Climate

Petroleum (Oil)

Concept: The term petroleum derives from petro (rock) and oleum (oil). It is the primary mineral resource of Venezuela, forming the foundation of the nation's entire economy.

Characteristics of Crude Oil

• Classification: Oil is typically classified as:
  1. Light Crude
  2. Heavy Crude (including bitumen)
• Purity Measurement: Its purity is determined by the API Gravity (American Petroleum Institute degree).
• Volume Measurement: Content is measured by the barrel, equivalent to 159 liters (approximately 42 US gallons).
• Crude oil is sometimes noted for having natural anesthetic properties.
• Derivatives: Many essential products are extracted from crude oil, including plastics, lubricants, textiles, gasoline, diesel, and kerosene.

Troposphere

The troposphere is the layer that contains 20% of all the gases of the atmosphere. Meteorological phenomena, such as clouds and precipitation, take place in the troposphere.

Stratosphere

The stratosphere is the layer that contains the ozone layer. This absorbs much of the Sun's radiation, so temperatures rise in the stratosphere.

Mesosphere

The mesosphere has very low temperatures, reaching -140°C.

Thermosphere

The thermosphere is also known as the ionosphere. Temperatures in this layer are very high.

Exosphere

The exosphere is the outer layer of the atmosphere. Artificial satellites orbit the Earth in the exosphere.

Natural Stone

River Rocks

Smooth and round. Used for decoration and pavements, especially in areas where children play.

Crushed Rocks

Irregular edges provide more friction. Used for paths or roads.

Types of Stone

Limestone

Porous, off-white sedimentary rock. Usually white and may contain animal fossils. Used for sculptures, buildings, and breakwaters.

Marble

Hard, dense metamorphic rock naturally formed from limestone. Cool to the touch and known for its resistance to compression and weather conditions. Available in a variety of colors and has a shiny finish when polished. Used for sculptures, decorations, columns, floors, and kitchen countertops.

Granite

Igneous rock composed of quartz, feldspar, and mica. Formed by the crystallization of volcanic magma...

Energy Sources

Energy is the ability of a system to do work. Chemical: stored energy contained in chemical compounds. Released during chemical reactions, electrical: produced by the flow of electric charge, thermal: released as heat, electromagnetic: stored in electromagnetic waves or radiation, mechanical: combination of two energies (kinetic: things in motion, potential: stored within an object), nuclear: stored in the nuclei of atoms (fission: nucleus splits, fusion: nucleus joins).

Non-Renewable Energy Sources

Non-renewable energy sources are limited energy resources obtained from beneath the Earth. They are being used faster than they can be replenished. Fossil fuels are formed from the remains of microorganisms, plants and animals buried...
