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...

At which altitude is it necessary to breathe

CLIMATE

  1. LATIDUDE
  • Latitude is the distance form any point on earth to the Equator.
  • Latitude determines the level of insolation at any point. Insolation is the amount of solar energy received. As we move further from the Equator insolation is less intense.
  • Latitude determines the main climate zones:
    • Tropical zones: from tropic of cancer to trpic of capricorn. There are high temperatures and abundant precipitation.
    • Temperate zones. Temperatures vary depending on the season and prcipitation is more abundant in areas near the sea.
    • Polar zones. Very low temperatures and low precipitation.
  1. ALTITUDE
  • Is the heigth of a place relative to sea level.
  • Temperature falls 0.6º for every 100 m
  • Relief can also cause precipitation when it causes moist air to rise and condense.

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,

Fig. Q1 c) RC Sea wall

  1. Comment on the level of exposure and describe the Most likely cause of the damage.

    Answer 1 b) i):

    The level of exposure in a coastal Environment can be severe and problems can arise due to a number of factors:

  • Erosion of the concrete surface due to wave action And abrasion due to sand being picked up and impacted against the sea wall.

  • Ingress of sea water under pressure with tidal Movement and

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
