The Changing of the Earth-Lesson 1
| Question | Answer |
|---|---|
| What type of weather occurs in the atmosphere | thunder, lightning, wind, and rain |
| What are some things the atmosphere does | it contains gases that organisms need to live, helps protect living things from being damaged by too much sunlight. |
| where is the atmosphere | close to the earth's surface |
| what happens to the air pressure as you go higher and higher | there is less and less gas and the air pressure decreases |
| what is beneath the atmosphere | the hydrosphere |
| what is the hydrosphere | the water part of the earth's surface |
| what does the hydrosphere include | oceans, lakes, rivers, streams, and glaciers. |
| how much of the earth's surface is covered by water | three-quarters of earth's surface |
| can life exist without water | no |
| where do we live | on the rigid outer surface called the lithosphere |
| what is the lithosphere | rigid outer shell of the earth |
| what does the lithosphere contain | rocks, soils,and minerals that plants need |
| what do plants need and where do they get it from | they need rocks,soil and minerals found in lithosphere |
| which layer is our house attached to | lithosphere |
| which layer are mines dug into | lithosphere |
| which layer surrounds earth | atmosphere |
| which layer is made up of gases | atmosphere |
| which layer is mostly water | hydrosphere |
| how are the parts of the lithosphere and the hydrosphere in the atmosphere | dust from the atmosphere and droplets of water and ice crystals from the hydrosphere are in the atmosphere |
| how are the parts of the atmosphere and lithosphere in the hydrosphere | solids from the lithosphere and gases from the atmosphere are mix in the oceans |
| how are the parts of the hydrosphere and atmosphere in the lithosphere | gases from the atmosphere and water from hydrosphere are underground |
| what are the layers of the lithosphere | all the crust and the rigid top part of the mantle |
| how thick is the crust | 40 kilometers in many places. |
| which part of lithosphere is solid rock | the crust |
| where is the temperature hotter in the crust | the inner edge is hotter than the surface |
| how thick is the mantle | 2900 kilometers |
| which part of lithosphere is partly melted rock | the mantle |
| what are the two layers of the mantle | the partly melted rock and the solid rock below it. |
| which part of mantle is hotter and why | the solid mantle is hotter because it is deeper, the temperature increases with depth |
| what is the distance from the outer edge of the core to the center of the core | 3500 kilometers |
| what is the outer part of the core made of | liquid iron and nickel |
| what is the inner part of the core made of | solid iron and nickel |
| what covers the entire earth | the crust |
| what is the middle layer of the earth called | the mantle |
| what layer is beneath the crust | the mantle |
| which is thicker the mantle or the crust | the mantle |
| describe the upper part of the mantle | rigid |
| what makes up the lithosphere | the rigid part of the mantle and the whole crust |
| what layer is the deepest | the core |
| which layer is the center part of the earth | the core |
| what is the core made of | iron and nickel |
| what is the difference btw the inner and outer part of the core | the outer part is liquid iron and nickel and the inner is solid iron and nickel |
| what happens to the temperature as you go deeper into the core | it rises |
| why does the inner part of the core turn to solid iron and nickel | because the pressure from earth above is so great it forces the melted iron and nickel to become a solid |
| describe the solid metal in the inner layer of the core | white hot |
| describe the inner core | white hot, the center of the earth, you can go no further. |
| what are the three parts of the earth that are visible from space | atmosphere, lithosphere and hydrosphere |
| which part of earth visible from space is mostly liquid | hydrosphere |
| which part of earth visible from space is mostly gas | atmosphere |
| which part of earth visible from space is mostly solid | lithosphere |
| what are the three layers of the earth | crust, mantle and core |
| which is the coolest layer of the earth | crust |
| which is the hottest layer of the earth | core |
| sequence beginning at the center of the earth-atmosphere,core,crust,hydrosphere,mantle | core, mantle, crust,hydrosphere, atmosphere |
