Questions?

1.What do you think a limnic eruption is?

2.If you were in a tsunami prone area were would you go?

3.What do you think a pyroclastic flow is?

Week 4:




Only felt by instruments.





Most people run outdoors. Damage to weakly constructed buildings. Felt by people in moving vehicles.





Felt by people at rest, especially on upper floors. Suspended objects may swing.



Considerable damage to most buildings. Heavy furniture overturned. Some sand fluidised.



Felt indoors. Vibrations like passing traffic.



Even well-designed and sturdy buildings badly damaged, moved from their foundations. Ground cracks. Pipes break.



Many people feel it indoors, a few outdoors. Crockery and windows rattle. Standing cars rock. Some sleepers awake.



Most masonry destroyed. Landslides occur. Water slops from reservoirs and lakes. Railway lines bend.



Felt by nearly everyone. Tall objects rock. Plaster cracks.



Few structures remain upright. Bridges fall. Extensive fissures in the ground. Underground pipes totally out of action.

Most people run outdoors. Damage to weakly constructed buildings. Felt by people in moving vehicles.



Total destruction. Ground thrown into waves. Objects flung into the air. You would be lucky to survive this one.

Layers of the atmosphere (not to scale)
Earth's atmosphere can be divided into five main layers. These layers are mainly determined by whether temperature increases or decreases with altitude. From highest to lowest, these layers are:

ExosphereThe outermost layer of Earth's atmosphere extends from the exobase upward. Here the particles are so far apart that they can travel hundreds of km without colliding with one another. Since the particles rarely collide, the atmosphere no longer behaves like a fluid. These free-moving particles follow ballistic trajectories and may migrate into and out of the magnetosphere or the solar wind. The exosphere is mainly composed of hydrogen and helium.ThermosphereTemperature increases with height in the thermosphere from the mesopause up to the thermopause, then is constant with height. The temperature of this layer can rise to 1,500 °C (2,730 °F), though the gas molecules are so far apart that temperature in the usual sense is not well defined. The International Space Station orbits in this layer, between 320 and 380 km (200 and 240 mi). The top of the thermosphere is the bottom of the exosphere, called the exobase. Its height varies with solar activity and ranges from about 350–800 km (220–500 mi; 1,100,000–2,600,000 ft).MesosphereThe mesosphere extends from the stratopause to 80–85 km (50–53 mi; 260,000–280,000 ft). It is the layer where most meteors burn up upon entering the atmosphere. Temperature decreases with height in the mesosphere. The mesopause, the temperature minimum that marks the top of the mesosphere, is the coldest place on Earth and has an average temperature around −85 °C (−121.0 °F; 188.1 K)[3]. Due to the cold temperature of the mesophere, water vapor is frozen, forming ice clouds (or Noctilucent clouds). A type of lightning referred to as either sprites or ELVES, form many miles above thunderclouds in the trophosphere.StratosphereThe stratosphere extends from the tropopause to about 51 km (32 mi; 170,000 ft). Temperature increases with height, which restricts turbulence and mixing. The stratopause, which is the boundary between the stratosphere and mesosphere, typically is at 50 to 55 km (31 to 34 mi; 160,000 to 180,000 ft). The pressure here is 1/1000th sea level.TroposphereThe troposphere begins at the surface and extends to between 7 km (23,000 ft) at the poles and 17 km (56,000 ft) at the equator, with some variation due to weather. The troposphere is mostly heated by transfer of energy from the surface, so on average the lowest part of the troposphere is warmest and temperature decreases with altitude. This promotes vertical mixing (hence the origin of its name in the Greek word "τροπή", trope, meaning turn or overturn). The troposphere contains roughly 80%[citation needed] of the

The moon effects the earth in two ways. Its position around the earth allows it to reflect the sun's light into our night. The moon's orbit around the earth lasts about a month giving us different levels of this light.
