| Question | Answer |
|---|---|
| solar energy | radiant energy emitted by the sun. |
| revolution | an instance of revolving. |
| rotation | the action of rotating around an axis or center. |
| latitude | the angular distance of a place north or south of the earth's equator, or of a celestial object north or south of the celestial equator, usually expressed in degrees and minutes. |
| tropics | the parallel of latitude 23°26ʹ north (tropic of Cancer) or south (tropic of Capricorn) of the equator. |
| fresh water | of or found in fresh water; not of the sea. |
| surface water | the top layer of a body of water. |
| precipitation | rain, snow, sleet, or hail that falls to the ground. |
| ground water | The definition of groundwater, or ground water, is water located beneath the surface of the earth. The water that your well draws from under the ground is an example of groundwater. |
| water vapor | Definition of water vapor. : water in a vaporous form especially when below boiling temperature and diffused (as in the atmosphere) |
| water cycle | the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration. |
| landforms | a natural feature of the earth's surface. |
| continents | any of the world's main continuous expanses of land (Africa, Antarctica, Asia, Australia, Europe, North America, South America). |
| plate tectonics | a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle. |
| lava | hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this. |
| earthquakes | a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action. |
| weathering | wear away or change the appearance or texture of (something) by long exposure to the air. |
| erosion | the process of eroding or being eroded by wind, water, or other natural agents. |
| landforms and process that impacts them | mountains, valley, islands, planes and peninsulas-weathering, erosion and water |
| water cycle | As liquid water evaporates or transpires, it forms water vapor and clouds, where water droplets eventually gain enough mass to fall back to Earth as precipitation |
| direct sunlight | Direct sunlight reaches the Earth's surface when there is no cloud cover between the sun and the Earth, |
| indirect sunlight | cloud cover causes indirect sunlight to reach the surface |
| North hemisphere | both hemispheres have opposite seasons, The Northern Hemisphere has much more of Earth’s land masses, while the Southern Hemisphere has a larger fraction of ocean. |
| effects on seasons, precipitation and temperatures | land and ocean heat and cool at different rates. Land heats up and cools down much faster (over a period of a day) compared with ocean (over a period of months). |
| dominant feature of earth | The ocean is the defining physical feature on our planet Earth—covering approximately 70% of the planet’s surface. |
| effects of ocean on water | The ocean is an integral part of the water cycle and is connected to all of the earth’s water reservoirs via evaporation and precipitation processes. |
| how people change land | They change it by destroying the land and building massive cities and other buildings on top of it. Also by creating man made rivers, mining, and other harmful things to the enviroment. |
| revolution, rotation and tilt | The sun burns the same at all times. Earth's elliptical orbit brings it closer or farther at different times of year. The important factor is the incident angle of sunlight. The same light is spread over a larger area, and is therefore much less intense. |
| solar energy effects on water cycle | This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration |
| When the North end of earths points at the sun, facts in the Northern hemisphere? | 1) The north end of the rotation axis is toward the sun receives for energy from the sun 3) the northern hemisphere receives more sunlight in June 4) This is when spring and summer happen in the northern hemisphere, |
| when the north end points away from the sun, During the other half of the earths orbit, | the north end of the rotation is away from the sun 2)receivers less solar energy in the 3) temperature will decrease in the north, but increase in the south 4)This is when fall and winter happen in the northern hemisphere, |
