EARTH SCIENCE REGENT
review for earth space sciences regents
| Term | Definition |
|---|---|
| kelvin [definition] | the scientific unit used for measuring temperature |
| kelvin [how can it be used] | kelvin is used to measure temperature, you canNOT god below 0 kelvin negative Kelvin does not exist, the lowest aka colder point of Kelvin is 0 or in Fahrenheit it’s -459.67 or In Celsius it’s -273.15 |
| meniscus [definition] | the curved surface of a liquid inside a container. For example a beaker. |
| what is water displacement? | water displacement is used to find the mass of irregularly shaped objects like rocks, |
| how do you calculate water displacement? | you can calculate it by 1. Setting a bottle with 100 ml of liquid (or however much you want) 2. Drop the object in (then record the data) 3. Subtract 100 ml ( or amount of liquid you used ) from the recorded 4. The rest remaining is the mass. |
| Density [definition] | An objects mass per unit volume |
| Density [formula] | m D = — v |
| density [formula] (breakdown] | M = mass V = volume D = density |
| Temperature [definition] | The measure of the average kinetic energy of molecules and atoms in a material. |
| 3 types of temperature [measurements] | Fahrenheit, Celsius, and Kelvin |
| Freezing point in Fahrenheit and Celsius | F = 32 C = 0 |
| Freezing point [kelvin] | K = 273.15 |
| Boiling point, [ Fahrenheit and Celsius | F = 212 C = 100 |
| Atomic mass [formula] | AM = protons + neutrons |
| Amplitude [definition] | Amplitude is the distance form the top line to the bottom line [think of it as the height of the wave] |
| Long wave length = | Low frequency |
| short wave length = | High frequency |
| Frequency [ definition ] | How many wave fronts pass a specific point per given amount of time |
| What electromagnetic wave on the light spectrum has the lowest frequency | Microwaves |
| What electromagnetic wave has the highest frequency in the light spectrum | ultraviolet |
| nm [measurement] | Nanometer |
| hz [measurement] | hertz = frequency |
| Name the 4 terrestrial planets | Earth, mars, Venus, mercury |
| name the 4 Jovian planet + exo planet | saturn, Neptune, uranus, Jupiter, PLUTO |
| Name properties of physical weathering | Frost action, abrasion, root wedging |
| Name the properties of chemical weathering | Dissolving “acid” , oxidation |
| Half life (definition) | Amount of time it takes for half of the original amount of radioactive isotope to decay. |
| what is radio metric dating? | The method used for getting the exact age for a material using the amounts of radioactive isotopes in it. |
| How do caves form | Ground water from limestone or other impermeable spaces dissolve the limestone over time causing breakage |
| permeable (definition) | allows water to pass through |
| Impermeable (definition) | does NOT allow water to pass through |
| How do large crystals develop | From slow cooling of Milton magma |
| What are the 3 rock types | igneous, sedimentary, metamorphic. |
