Shakira in the atmosphere!

What are the 5 layers of the Earth´s atmosphere ? (in order from the outside to the inside)

• the exosphere, the thermosphere,

  the mesosphere and the troposphere

• the exosphere, the thermosphere, the exosphere, the thermosphere and the stratosphere

• the exosphere, the thermosphere,

  the mesosphere, the stratosphere and the troposphere

• the thermosphere,

  the mesosphere, the exosphere, the stratosphere and the troposphere

The Earth’s________has five layers: the exosphere, the thermosphere,

the_______ , the stratosphere and the troposphere._______ pushes the

densest gases towards the layers closest to the Earth’s surface

• atmosfere/ mesosphere / Gravity

• atmosphere/ mesosphere / Gravity

• mesosphere /atmosphere / Density

• atmosphere/ mesosphere / Ozone

__________ is 12 km above sea level. This is where we find ideal conditions for life. We also find meteorological

phenomena, such as wind and rain here. The troposphere contains 90% of the total mass of atmospheric gases.

• The troposphere

• the stratosphere

• the thermosphere

• the mesosphere

• the exosphere

The gases that form_________ move horizontally. The

ozone layer is here, 25 km away from the Earth’s surface.

Temperatures increase as the altitude3 increases.

• The troposphere

• the stratosphere

• the thermosphere

• the mesosphere

• the exosphere

In_____________ temperatures drop to –100 °C. When small

meteorites break up in the thermosphere, shooting stars

appear in the mesosphere

• The troposphere

• the stratosphere

• the thermosphere

• the mesosphere

• the exosphere

_________________ absorbs the most powerful radiation from

the Sun, such as X-rays. That’s why temperatures here can

reach 1 000 °C.

• The troposphere

• the stratosphere

• the thermosphere

• the mesosphere

• the exosphere

The__________ has a very low concentration of gases.

• The troposphere

• the stratosphere

• the thermosphere

• the mesosphere

• the exosphere

What are the two most abundant gases in the atmosphere?

• oxygen (78%) and nitrogen (21%)

• nitrogen (78%) and oxygen (21%)

• nitrogen (78%) and carbon dioxide (21%)

• nitrogen (78%) and water vapour (21%)

The most abundant gases in the atmosphere

are nitrogen and oxygen. There are also smaller percentages of

other gases, such as __________, water vapour,_____, helium and argon.

• air / wind

• gravity / pollen

• carbon dioxide / ozone

• carbon dyoxide / ozone

The atmosphere also has solid particles suspended in it.

• true

• false
