Earth Science Concepts
Water Cycle Questions 1.Define transpiration- the process of plants releasing water vapor 2.Define evaporation- liquid water gains enough energy and turns to water vapor 3.When water evaporates and cools, what occurs? 4.After precipitation occurs, what happens to the water?
Rock Cycle Questions 1.How does sedimentary rock change into metamorphic rock? high temperature & pressures 2.What is magma? molten rock beneath Earth’s surface
Hardness Definition how resistant a substance is to scratching the relative capacity of a substance for scratching another or for being scratched or indented by another
Moh’s Hardness Scale
Moh’s Hardness Scale Questions 1.What mineral can scratch all others on the data table? Diamond 2.What minerals can be scratched by calcite? Gypsum and Talc 3.Can quartz scratch topaz? Why or why not? No, quartz is softer than topaz.
Earthquakes 1.What is the epicenter? the area above the focus on the Earth’s surface 2.What are P waves? Primary- travel through solids, liquids & gases pushing rock particles ahead 3.What are S waves? Secondary- travel through solids moving rocks at right angles to wave motion 4.Which wave travels faster? P waves 5.What kind of wave causes the most damage and why? L waves- originate at the epicenter & moves surface up & down
Fronts and Low Pressure Cold air is present behind the cold front on both diagrams.
High Pressure Systems What happens after a high pressure system passes through a location? Happy weather- sunshine and dry
Low Pressure Systems What happens after a low pressure system passes through? Lousy weather- cloudy and precipitation
Volcanic Eruptions 1.During an eruption, what is ejected into the atmosphere? volcanic ash & gases 2. How can this affect the climate? cooling 3. Can an eruption cause global changes? Yes
Atmosphere Composition- What are the two most abundant gases in our atmosphere? Nitrogen & Oxygen Altitude- as altitude increases, temperature? Decreases Air pressure- as altitude increases, air pressure? Decreases
Graphs Complete the questions by analyzing the graphs and data table.
