What are the types of Mechanical Weathering? | Ice Wedging, Abrasion, Burrowing, Plants |
After repeated freezing and thawing, rocks can weather rapidly because of the _________ of freezing water. | expansion |
The layer of the atmosphere that is closest to Earth's surface is called ________. | troposphere |
Which type of heat transfer involves the flow of particles within matter? | convection |
Which type of heat transfer requires particles to collide? | conduction |
Which type of heat transfer transfers energy through rays or waves? | radiation |
The layer of the atmosphere that contains the ozone layer is the _______. | stratosphere |
The coldest layer of the atmosphere is the _________. | mesosphere |
Name the layers of the atmosphere in order starting from the Earth's surface. | troposphere, stratosphere, mesosphere, thermosphere, exosphere |
What happens during a cold front? | colder air is pushed underneath the warmer air. Warm air rises and cools and clouds form causing precipitation. |
What are short term variations in the atmosphere called? | weather |
What is a long term average of conditions that occurs in a particular region? | climate |
On a day with high humidity, your skin might feel sticky, Why? | Because there is an increase in water vapor in the air |
The amount of water vapor present in the air compared to the maximum amount of water vapor the air could contain at a certain temperature is called _________. | relative humidity |
Why do hurricanes result in more damage than a tornado? | they are associated with flooding and strong winds, they are much larger than a tornado, and they last longer than a tornado |
Weather or Climate? It rained an average of 30 inches for the past 10 years. | Climate |
Weather or Climate? The temperature is going to be in the 80's for the next few days. | Weather |
Chemical weathering happens more rapidly in what type of environment? | warm, wet |
Why is more force needed to push a wheelbarrow after filling it with dirt? | because the total mass of the wheelbarrow increases after adding the dirt. |
Kinetic energy is the energy of _______. | motion |
Potential energy is __________ energy. | stored |
What is a front? | Boundary between 2 air masses |
Name the 4 major Earth Systems. | Biosphere, Hydrosphere, Atmosphere, Geosphere |
Weathering is the ______ down of rock. | breaking |
Erosion _______rock away. | carries |
Deposition ______ __ ____. There it stays until it is eroded again someday. | drops sediment off |
Atmospheric pressure _________ as altitude increase. | decreases |
Why is Earth's atmosphere so important? | it acts an insulator protecting Earth from extreme temperatures, harmful rays, protects life, protects Earth's surface from being struck by meteors. |
Precipitation is ________ | water in a liquid or solid form that falls from the atgmosphere |
An air mass that forms over a tropical ocean would have which type of air associated with it? | warm, moist air |
As water evaporates, it enters the _________. | atmosphere |
What is the beginning of the water cycle? | There is no beginning or end, it a continuous cycle. |
What is the composition of the Earth's atmosphere? | 78% Nitrogen, 21% Oxygen, 1% other gases |
What is the source of all energy in our atmosphere? | the sun |
Explain what happens to the Potential energy of a ball as it falls to the ground. | Potential energy decreases as the kinetic energy increases |
List the 3 main weathering agents. | water, wind, and ice |
Describe how wind is a weathering agent. | it grinds and polishes rock by blowing particles against them. |
Describe how water is a weathering agent. | it dissolves minerals in rock. |
Describe how ice is a weathering agent. | it breaks rock apart as it expands within cracks in the rock. |
