6.Landforms geographical features which can be observed on the Earths surfac.Landforms are dynamic,caused by the opposition action of-internal process:these tend to built&lift them.-External process:led to shape them.They are differ.Types that are characteristic of each morphoclimatic zone:glacial,periglacial,desert,semi-desert&fluvial .6.1Glacial landforms:the climate causes snow to accumulate year after year.This is transformed into ice,which prevets vegetat. From growing. 6.2Periglacial landforms:allows the growth of sparse vegetat.Such as lichens. 6.3Deset landf:characterized by infrequent precipitation&intense evaporation.The conseq is little vegetat.&hardly any water in the ground during most of the year. 6.4Semi-desert

Written at on English with a size of 5.1 KB.

Ozone (O3 ) is a made with three oxygen atoms; it is very unstable and has a short lifetime. At room Temperature and pressure has acrid odour and no colour, although at high concentration levels can turn Into blue. At high concentrations can be toxic and can cause death. It s not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight. VOC + NOx + sunlight tropospheric O3Particulate Matter (PM) "Particulate matter," also known as particle pollution or PM, is a complex mixture of extremely small Particles and liquid droplets. Particle pollution is made up of a number of components, including acids (such as nitrates and sulfates), organic...

Income from the forest

Classified in Geology

Written at on English with a size of 1.21 KB.

In this text I am going to talk about global warming.
Global warming is the observed increase in the temperature of the Earth's climate system and the effect of that increase.

Some of the causes of this phenomenon are: Greenhouse gases, this gas traps heat in the Earth's atmosphere, also when we burn fossil fuels, carbon dioxide is produced and as more and more carbon dioxide goes into the atmosphere, we begin to trap more heat and the Earth gets warmer. When the Earth gets warmer, there are changes in the weather, and sea levels rise, also glaciers melt and there are forest fires.

As a conclusion I think that the only ones that can solve this problem is us, by saving energy, usic public transport , recycling, controlling the felling of trees,

Alexander mery history

Written at on English with a size of 3.08 KB.

Spontaneous generation: life began from inanimate objects. Oparin’s theory: Alexander Ivanovich Oparin developed this abiogenic theory. 1.Components atmosphere (methane, ammonia, hydrogen and water vapour) reacted due to the energy of the storms, solar radiation and continuous volcanic eruptions creating simple organic molecules. 2.Earth cooled down, intense rain produced primitive seas, where organic molecules accumulated. 3.Organic molecules joined, creating bigger molecules; some of them were insulated from the water inside structures calles coacervates. 4. Some of the coacervates developed molecules in their interior that were able to self-replicating; these were the first organisims and the origin of all cells. Panspermia theory: life

By volume what percentage of the air in the lower troposphere consists of water vapour

Classified in Geology

Written at on English with a size of 2.77 KB.

    WATER IN THE OCEANS 
  • SALT WATER: oceans and seas cover 71%of the earth´s surface . Most of the water on the planet is salt water. Rivers and rain carry rocks and minerals to oceans and seas ; this makes thm saline. Not all seawater hast the same salinity. Water in landlocked seas and in warmer latitudes is usually saltier, because the heat causes more evaporation than in open and cold seas.
  • WATER IN MOVEMENT: Seawater is constantly moving because of the movement of curents, tides and waves. This movement erodes and shapes coastlines. Ocean currents are like big rivers moving within the oceans. The water in these currents does not mix with the rest of the sea because it has a different temperature or salinity. Currents can be warm or

Water Cycle : the natural sequence through Which water passes into the atmosphere as water vapor, precipitates to earth in Liquid or solid form, and ultimately returns to the atmosphere through evaporation.

Sequence Of the water cycle proces :

Evaporation : water molecules in liquid state escapes into the air as Water vapor. /

Condensation: molecules Of water vapor in the air become liquid water. / Precipitation: any from of water that falls from clouds and Reaches Eath’s surface. /

Collection: This is when water runs off slopes.

Info: hydrological cycle: pathway of Water from the atmosphere to Earth’s surface, bellow ground and back. / Biogeochemical cycle: movement of A chemical through the biological and geological, or living and nonliving,

First step in forming sedimentary rock

Classified in Geology

Written at on English with a size of 1.38 KB.

KARST LANDFORM- A modelling that takes place in limestone masses due to the action of water with dissolved carbon dioxide from the atmosphere.  The CO2 reacts with the calcium carbontae in the limestone adn transforms it into calcium bicarbonate. This is a type of chemical weathering callled carbonatation. The inflitrationof water slowly alter and soddolves the limestone, making the cracks and fissures in the rock and creating lapies, dolines, poljes, galleries and caverns. In the cavities, the dissolves calcium bicarbonate can be transformed back into insoluble carbonate, creating stlactites and stalagmites. JOINTS-Are short, narrow cracks that appear in a rock mass without the cracked blocks moving at all. EROSION- The progressive wearing

In which of the following areas do surface high pressure systems usually predominate over the north atlantic region between 30°n and 65°n and the adjoining land areas during the northern summer?

Climate refers to the typical weather that a place experiences over many years. Different parts of the world can be described as havinga dry, wet, hot or cold climates.

There has been many schemes to clasify climates. The classification most use nowadays was developed between 1884-1940 by the German climatologyst  Wladimir Peter Koppen (1846-1940)
Koppen divided climates into six principal types designated by the letteres A-F, with highland climates forming a seventh. Within these categories other letteres provide further information.

Subtropical Canary islands. Winter 14ºC, Summer 22º degrees celsius
Mediterranean,Total rainfall in this region is lower than in the rest of Spain, it's concentrated in the late autumn-winter period. Rainfalls
