Which of the following is not a method of heat transfer?
reflection |
|
convection |
|
conduction |
|
radiation |
Heat is always transferred from warmer to cooler environments through conduction, convection, or radiation.
The hottest of Earth's atmospheric layers is which of the following?
mesosphere |
|
stratosphere |
|
thermosphere |
|
troposphere |
Temperatures again increase with altitude in the thermosphere which is the hottest (4,530 °F / 2,500 °C) atmospheric layer due to direct exposure to the Sun's radiation. However, the gas in this layer is highly diluted so even though the atoms of gas may be very high in temperature, there are too few of them to effectively transfer much heat.
What kind of weather front is likely to create clouds and storms?
cold front |
|
stationary front |
|
warm front |
|
temperate front |
A warm front is the boundary between warm and cool (or cold) air when the warm air is replacing the cold air. Warm air at the surface pushes above the cool air mass creating clouds and storms.
