The biosphere includes parts of the Earth's surface and atmosphere where living things exist.
The biosphere is where other spheres of the planet interact:
- The land (lithosphere) interacts with the water (hydrosphere).
- The land interacts with the air (atmosphere).
- Living things interact with the land, water and air. 

Lithosphere (Mrs Baker) 
layer of land, e.g. hills, planes

Hydrosphere (Mrs Baker) 
 layer of water, e.g creeks, oceans

- Earthquakes
- Volcanoes
- Tropical Cyclones

These Natural events influence the Atmosphere, Lithosphere and hydrosphere. 
They also cause the different spheres to interact in different ways.

Causes:- An earthquake occurs when the rocks break and move as a result of stresses caused by plate movements.
Effects on environment/people:- Can cause large cracks to appear or land to increase in height, may also cause mud/landslides,
Example:- Christchurch]]> 2017-12-10 22:31:14 UTC https://padlet.com/carolyn_j_baker/qfhkx7s6r5ot/wish/214863820 Volcanoes- Bridget and Adam carolyn_j_baker https://padlet.com/carolyn_j_baker/qfhkx7s6r5ot/wish/214863968 Definition/causes:-  a mountain or hill, having a crater or vent through which lava and rock fragments as well as hot vapour and gas are or have been erupted from the earth's crust. 
Effects on environment/people:- Volcanic eruptions can send large clouds of ash into the atmosphere which then can produce rain and lightening. This reduces the amount of sun that reaches the earth which has a cooling effect making for a colder atmosphere which can lead to crop and livestock failure.
Example:- Krakatau in Indonesia had an eruption in 1883 which lead to a global decrease in temperature of 1.2 Degrees Celsius. The sulfur dioxide released into the atmosphere from the eruption later reacted with the water in the atmosphere

In the southern hemisphere the onshore winds occur to the left of the tropical cyclone's path 
Effects on environment/people:- The destruction from a tropical cyclone depends mainly on its intensity, its size, and its location. ... Nearly two million people have died globally due to tropical cyclones.

Even through the individual molecules are changing, the amounts of different elements within the atmosphere stays amazingly steady. 
 Even though the amount of most gases in the atmosphere is quite steady, scientists have found that the amount of greenhouse gases in Earth’s atmosphere has increased over the last 150 years. The rise in amount of greenhouse gases is directly related to human activities such as the burning of fossil fuels, deforestation, and curing of concrete. These activities are affecting Earth’s cycles such as the carbon cycle, the nitrogen cycle and the water cycle, influencing the planet as a whole. 
Greenhouse gases trap heat through the greenhouse effect. There were greenhouse gases in the atmosphere long before humans affected the system. Having some greenhouse gases in Earth’s atmosphere is beneficial because they keep temperatures mild and suitable for life. However, as the amount of greenhouse gases has risen, so has Earth’s global temperature. This is causing changes to environments and ecologies around the world.

  • The tilt of the earth's axis and the earth's movement around the sun causes the four seasons (Summer, Autumn, Winter, Spring). If the tilt of the earth was different, the characteristics of the seasons would also be different.
  • As the earth rotates, the atmosphere and oceans move with it.

    Pollen grains and spores form the basis of another important aspect of palaeoclimate reconstruction, generally referred to as pollen analysis, or palynology. Where pollen and spores have accumulated over time, a record of the past vegetation of an area may be preserved. Often, changes in the vegetation of an area may be due to changes of climate. Interpreting past vegetation through pollen analysis may therefore offer a form of palaeoclimatic reconstruction.]]>     2017-12-10 22:42:56 UTC https://padlet.com/carolyn_j_baker/qfhkx7s6r5ot/wish/214864800     Sea level change evidence of climate change- Bryce carolyn_j_baker https://padlet.com/carolyn_j_baker/qfhkx7s6r5ot/wish/214864819 The coastal rocks are slowly but consistently rising as a consequence of the growth of the Andean mountain chain. The ocean acts like a battering ram, and cliffs recede under the constant barrage of waves — bit by bit, a gently sloping beach or, in geological terms, a marine terrace is generated.

    Sources of nitrous oxide:-

    Nitrous oxide is emitted by bacteria in soils and oceans, and is thus a part of Earth's atmosphere. Agriculture is the main source of human-produced nitrous oxide: cultivating soil, the use of nitrogen fertilisers, and animal waste handling can all stimulate naturally occurring bacteria to produce more nitrous oxide.

    How have nitrous oxide levels in atmosphere changed? They have increased rapidly
