Multiple Choice

Water vapor is MOSTLY found in...

• exosphere

• stratosphere

• mesosphere

• troposphere

Troposphere

• The troposphere, an atmospheric layer, is where most of the Earth's weather takes place and it contains almost all of the water vapors.

Multiple Choice

Weather patterns can be observed in which layer?

• mesosphere

• exosphere

• troposphere

• thermosphere

The Troposphere: Where Weather Happens

Of all the atmosphere's layer's, the troposphere is the one we're most familiar with (whether you realize it or not) since we live at its bottom - the Earth's surface. It hugs the Earth's surface and extends upward to about high. Troposphere means, ‘where the air turns over’.

Multiple Choice

Which layer of the atmosphere contains the ozone?

• troposphere

• exosphere

• stratosphere

• thermosphere

Ozone Layer

About 90% of the ozone in the Earth's atmosphere is found in the region called the stratosphere. This is the atmospheric layer between 16 and 48 kilometers (10 and 30 miles) above the Earth's surface. Ozone forms a kind of layer in the stratosphere, where it is more concentrated than anywhere else.

Multiple Choice

This greenhouse gas traps heat in the atmosphere making the earth livable.

• nitrogen

• oxygen

• ozone

• carbon dioxide

Carbon Dioxide

Before humans began burning fossil fuels, naturally occurring greenhouse gases (carbon dioxide) helped to make Earth’s climate habitable. Without them, the planet’s average temperature would be below freezing.

Multiple Choice

The MOST abundant gas in the atmosphere...

• oxygen

• carbon dioxide

• agon

• nitrogen

Composition of Air

Nitrogen is the MOST abundant atmospheric gas.

Multiple Choice

The cloud with vertical development...

• cirrus

• cumulus

• stratus

• cumulonimbus

Cloud Atlas

Cumulonimbus is the only cloud that has vertical development. It is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents. If observed during a storm, these clouds may be referred to as thunderheads.

Multiple Choice

Which is TRUE - density and pressure…

• decreases as altitude decreases

• increases as altitude decreases

• decreases as altitude increases

Pressure, Density & Altitude

In the atmosphere, as we increase altitude the pressure decreases which will decrease the density. As you say, the temperature also decreases which will try to INCREASE the density. But the influence of the drop in pressure is very much more powerful. It wins this battle easily and so the actual density decreases.

Multiple Choice

What is the relationship between atmospheric altitude and pressure?

• directly proportional

• inversely proportional

Pressure & Altitude

Atmospheric pressure reduces with altitude for two reasons, both of which are related to gravity. Atmospheric pressure reduces with altitude for two reasons, both of which are related to gravity.

Multiple Choice

What is the relationship between atmospheric altitude and density?

• directly proportional

• inversely proportional

Density & Altitude

Altitude is height above sea level. The density of air decreases with height. There are two reasons: at higher altitudes, there is less air pushing down from above, and gravity is weaker farther from Earth's center. So at higher altitudes, air molecules can spread out more, and air density decreases.

Special Pointers in Atmosphere - Part 1

Study about the different typhoon hazards in the Philippines including the ways on how to mitigate its impact to our infrastructure, agriculture and to our lives .

Special Pointers in Atmosphere - Part 2

Study on water conservation strategies that can potentially help address the threat of water shortage in the Philippines.
