Atmoshpere

Question 1

Atmosphere

Answer 1

the envelope of gases surrounding the earth or another planet.

Question 2

Conduction

Answer 2

the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

Question 3

Convection currents

Answer 3

a current in a fluid that results from convection.

Question 4

Corilolis effect

Answer 4

an effect whereby a mass moving in a rotating system experiences a force (the Coriolis force ) acting perpendicular to the direction of motion and to the axis of rotation.

Question 5

Global winds

Answer 5

Global Winds are the dominant prevailing wind patterns that blow in a fairly constant

Question 6

Greenhouse effect

Answer 6

the trapping of the sun’s warmth in a planet’s lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet’s surface.

Question 7

Ionosphere

Answer 7

the layer of the earth’s atmosphere that contains a high concentration of ions and free electrons and is able to reflect radio waves.

Question 8

Local winds

Answer 8

one of a number of winds that are influenced predominantly by the topographic features of a relatively small region.

Question 9

Sea Breeze

Answer 9

a breeze blowing toward the land from the sea, especially during the day owing to the relative warmth of the land.

Question 10

Stratosphere

Answer 10

the layer of the earth’s atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth’s surface

Question 11

Temperature

Answer 11

the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

Question 12

Thermal energy

Answer 12

Thermal energy is an example of kinetic energy, as it is due to the motion of particles, with motion being the key.

Question 13

Thermosphere

Answer 13

the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium.

Question 14

Troposphere

Answer 14

the lowest region of the atmosphere, extending from the earth’s surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.

Question 15

Windchill Factor

Answer 15

Windchill factor is the perceived decrease in air temperature felt by the body on exposed skin due to the flow of air.
