| Question | Answer |
|---|---|
| What is weather? | The daily conditions of the atmosphere at a specific time and place in terms of temperature, atmospheric pressure, wind, and moisture. |
| What are some measurements scientists use to describe weather? | wind speed and direction, pressure, humidity, temperature, and precipitation, including rain and snow |
| What is climate? | the weather conditions prevailing in an area in general or over a long period |
| How is climate similar and different than weather? | SIMILAR: they both share information about the atmosphere DIFFERENT: weather is a specific time and place and climate is a general (prevailing) description of the atmosphere in a particular place (not a specific time) |
| What factors have a large impact on an area’s climate? | -Energy from sun -Ocean currents -Large bodies of water -Landforms -Wind -altitude |
| If the altitude of a place is higher what happens to the climate of that place? | It will be cooler. Higher altitude = colder temperatures |
| Where is most of the water on Earth contained? | Oceans |
| About what percentage of Earth is covered by water? | 75% |
| What takes longer to heat up and cool down, land or water? | water |
| What is an ocean current? | a continuous, directed movement of seawater Currents are responsible for circulating water throughout the earth's oceans |
| How do ocean currents affect climate? | Ocean currents moderate climate. Cold weather-warm water-warms adjacent areas Hot weather-cold water-cools adjacent areas *Ocean currents move water - causes warmer/cooler climates than expected in some places |
| The Gulf Stream is a warm water ocean current that affects the east coast of the United States. What does this type of current do to the climate of those places? | Climate will be warmer than other places along that latitude that are not affected by the current |
| What are the layers of the atmosphere from lowest to highest elevation? | Lowest: Troposphere, Stratosphere, Mesosphere, Thermosphere |
| What are the different layers of the atmosphere based on? | temperature |
| What layer of the atmosphere do people live in? | troposphere |
| What parts of the atmosphere remain the same at every altitude? | percent of nitrogen, oxygen and argon gas |
| What parts of the atmosphere change as altitude changes? | percent of water vapor, temperature and pressure |
| True or false: Air gets thinner as altitude increases because there is a lower percentage of oxygen. | False. The % of oxygen remains the same throughout the atmosphere. |
| What are the main components of Earth’s Atmosphere? | percent of gasses, water vapor, temperature and pressure |
| What is an anemometer? | instrument used to measure wind speed |
| What does it mean if an anemometer is spinning faster? | Wind is blowing fast |
| What is a wind vane? | Instrument used to measure wind direction |
| What is a thermometer? | An instrument used to measure temperature |
| What is the prevailing wind? | The most common wind direction |
| What direction is the prevailing wind that affects New Jersey? | Wind is coming from the South West |
| How do you calculate mean? | Add up your numbers, Divide by the number of numbers in the set of data |
| How do you calculate median? | Write the numbers in numerical order Find the middle number *if you have an even number of numbers, average the two middle numbers |
| How do you calculate mode? | Write the numbers in numerical order Count how many times each number appears Number most repeated is the mode (may have no mode, one mode or many) |
| How do you calculate range? | Subtract the largest number minus the smallest |
