| Question | Answer |
|---|---|
| The difference between opaque, translucent and transparent | Opaque: does not allow light to pass through Translucent: allow light to pass through, but not clearly Transparent: allow light to pass through |
| What causes wind? | Air moves from a place with high pressure to a place with low pressure. The moving air is called wind |
| How do clouds form? | The sun's energy causes water in oceans, lakes, rivers to evaporate, a change from liquid to gas. Warm air rises from the surface of the earth, and carries water vapor. The warm air cools as it rises, and water vapor in the air begin to condense |
| How do clouds form? | 1.-The sun's energy evaporates water in oceans, lakes, rivers 2.-Warm air rises from the surface and carries water vapor 3.-The warm air cools as it rises and water vapor begins to condense as tiny drops 4.-The tiny drops stay in the air and form cloud |
| The difference between STRATUS, cumulus and cirrus clouds | Low clouds that form flat and wide layers. Sometimes he cover the whole sky and block the sunlight. Rain or snow may fall. |
| The difference between stratus, CUMULUS and cirrus clouds | Forms when warm and moist air moves high into the sky. They can be seen around midday or in the afternoon, when the air near the earth gets warm. Are dome shapped with flat bottoms. Cumulus are often in fair weather |
| The difference between stratus, cumulus and CIRRUS clouds | Are formed high in the sky where temperature is very cold. Formed mostly of ice crystals. Cirrus clouds look like thin threads or feathers arranged in bands. Cirrus clouds often mean that warm air is on the way |
| How does water move through the water cycle? Evaporation, condensation and precipitation | Water is always moving from the earth into the air and backs to earth again. |
| How does water move through the water cycle? EVAPORATION, condensation and precipitation | Water from lakes, rivers, and oceans evaporates into the air when warmer. The warmer the air, the faster the water get into the air as water vapor |
| How does water move through the water cycle? Evaporation, CONDENSATION and precipitation | When warm, moist air gets into a cool area, the water vapor condenses, forming tiny water drops. As the water vapor condenses, clouds are formed |
| How does water move through the water cycle? Evaporation, condensation and PRECIPITATION | Water drops fall from the cloud. It´s raining. In freezing temperatures, the water falls as snow. Most precipitation falls over the ocena |
| List three kinds of landforms found on the earth | 1.- Mountain 2.- Plain 3.- Plateau |
| How do volcanoes change the surface of the earth? | The surface of the earth is always changing. An erupting volcano changes the earth quickly. Because a volcano is a mountain formed by hardened lava. The mountains are one of the earth landforms |
| What causes earthquakes? | The shaking of the ground caused by rock movement along a fault |
| How do ocean currents affect the earth? | Because it affects the weather patterns around the world. The wind changes, the animals movements too. |
| What causes tides? | The moon. The moon and the earth are pulled toward each other by gravity. It keeps the moon moving around the earth. The moon pulls the ocean water and the land. The difference causes tides |
