| Question | Answer |
| Name 2 gases found in the atmosphere | Oxygen Carbon Dioxide Nitrogen |
| What does the atmosphere do for us? | Keeps oxygen in Keeps the Earth from getting too hot & too cold |
| What does latitude mean? | Distance from the equator |
| Is the earth's heat evenly distributed? | No. The equator receives more heat than areas to the north or south. |
| Atmospheric pressure | This is the weight of the air on the earth's surface. |
| High pressure | Cold air. Lots of pressure on the Earth's surface. |
| Explain what is happening in this diagram? | Rays over equator are strongest Have least distance to travel They are concentrated Rays to north/south are weaker They have farther to travel They cover a large area |
| Low pressure. | Warm air. Warm air rises. Less pressure on the surface. |
| Winds move from..... pressure areas to .... pressure areas. | High pressure to low pressure. |
| Coriollis effect | Spinning of earth impacts ts wind direction. |
| Doldrums | Areas of low pressure at the equator |
| Trade winds | So called as the blow towards the Equator. |
| Prevailing winds | Winds that blow most often over an area. |
| Altitude | Height above sea level |
| Aspect | The direction a slope is facing |
| Which slope gets the most sunlight in Ireland? | South facing |
| North Atlantic drift | Warm current that flows towards Ireland |
| Name two cold currents | Labrador Canaries |
| The sea heats ....... and cools ..... while the land heats ...... and cools ...... | The sea heats slowly and cools slowly while the land heats quickly and cools quickly. |
| Name a hot climate type | Hot desert climate |
| Give an example of a desert | Sahara |
| List 3 kinds of climatic zone | Hot Temperate Cold |
| Distance from the ocean | |
| Name 2 characteristics of a hot desert climate | Temperature & rainfall |
| What is the distribution of a hot desert? | 15/30 degrees N/S of equator |
| List 4 factors that influence the characteristics of this climate | Latitude Prevailing winds Ocean Currents Relief |
| How hot & how cold can it get here? | 30 degrees at day & -6 at night |
| Explain the role of clouds in the desert | Keeps heat in at night and keeps it out during the day |
| How much rainfall is experienced here? | less than 100 mm |
| Name the mountain providing relief for the Sahara desert. | The Atlas mountains |
| 1. Anti trade winds 2. Doldrums 3.North West anti trades | |
| Ocean Currents are caused by these 3 things; | Prevailing winds Unequal heating of the Earth Coriolais effect |
| What is an air mass? | a body of air with its own temperature, pressure, and humidity level. |
| Name the 4 air masses that impact Ireland | 1. Polar Air Masses (North Wind) 2. Continental Air Masses (East Wind) 3. Tropical Air Masses (South Wind) 4. Maritime Air Masses (South Westerly Wind) |
| What is a front? | Boundary between 2 air masses |
| Name two types of front | Warm Cold Occluded |
| Name this weather symbol | Cold front |
| Describe a Depression | Low pressure (Aka clone or Low) Oval in shape Lowest pressure in the middle Wet, windy weather Common over Ireland Lots of cloud Air moves into centre in anti clockwise direction |
| Anticyclone | High pressure (High) Cold air Oval in shape Larger than a Depression Pressure highest at center Air blows outwards from center Dry, settled weather |
| Name this symbol | Warm front |
| Name this symbol | Occluded front |
| Isobars | Lines of equal pressure on a weather map Closer the lines the more windy it is Measured in Ha or in millibars Moves at intervals of 4 |
| Cumulus clouds Medium height White or dark Can bring showers of rain | |
| Cirrus clouds High altitude Brush strokes Dary, settled weather | |
| Stratus clouds Low to ground Dark colour Long spell of ain |
