Earth's Spheres & The Layers of the Earth

What is one example of another word you hear "geo" in? Why is the geosphere like the skeleton of our planet? Which landforms are part of the geosphere? (HINT: there are four) Oceans Mountains Volcanoes Rivers Beaches Canyons Lakes The geosphere includes only ----- things. Living Non-living 1. The hydrosphere includes all water - fresh and salt. It also includes frozen water in glaciers.2. Water found in the ground is also part of the hydrosphere.3. The atmosphere includes the gases found in and around the planet.4. The atmosphere is like a blanket because it covers Earth.5. The troposphere is where weather occurs and 80% of Earth's air is located. Draw a line to match the sphere to its definition Geosphere Sphere that includes rocks, landforms, minerals and extends down to Earth's core Biosphere Sphere that includes all of Earth's living things Atmosphere Sphere that includes all of the gases that allow living things to survive on Earth Hydrosphere Sphere that includes all of the water on Earth Label elements of the biosphere, hydrosphere, atmosphere, and geosphere on the picture. Geosphere Hydrosphere Geosphere Atmosphere Biosphere Biosphere Hydrosphere Geosphere Rock Soil Mountains Stream bed Biosphere Grass Trees Birds Deer Hydrosphere Ocean River Rain All forms of precipitation Atmosphere Clouds that hold rain Wind Air How do scientists know how hot the core is? Thermometers Seismic waves Oil wells Measure the electromagnetic spectrul What would be the best title for this passage? How scientists explore the inside of the earth Details about each of the Earth's layers Tectonic plate mania The rock cycle The Earth's core is about the size of ---. Saturn Pluto The United States New York City The deepest wells and holes can make it to which layer? Crust Mantle Inner Core Outer Core How far have humans been able to drill into the Earth? What scientific principle causes the different layers of the Earth? Which two elements are found in the inner core? Are they solids or liquids? interface 1. Click on the blue box and allow adobe flash to run.2. Click through each of the layers and listen to the information about each layer.3. Answer the following questions. What is the average thickness of the Earth's crust? 5-100 km 100-200 km 200-300 km 300-400 km What causes the lithosphere to move? Ocean currents Rotation of solar system Convection currents Gravity Which layer of the Earth contains convection currents? Crust Mantle Core None Compare the density of the outer core to the density of the crust, mantle and inner core. Click on each blue dot and enter the name of each layer.Type it EXACTLY as I have in the list: Outer Core -- Mantle -- Crust -- Inner Core Using the above picture, answer the following questions. Layer 1 is the thinnest layer and made up mostly of granite and basalt. If you think about the outer layer of an apple, the Earth's crust would be compared to that. Do you think this is the densest layer or least dense layer? Why Layer 2 is the thickest layer and made up of mostly magma, which is lava within the Earth. There are convection currents in the mantle that cause the tectonic plates to move as the heat flows. Why do you think we know very little about layer 2? Layer 3 is made up of mostly liquid iron and Nickle. Scientists believe the magnetic properties of the Earth are caused by this layer of the Earth. Why do you think the outer core is liquid and the inner core is solid? Layer 4 is made up of mostly solid iron and Nickel. It is the Earth's densest layer. Even though it's as hot as the surface of the Sun. It is solid. How do you think scientists are able to study the center of the Earth? Earth's Crust Composed of mostly granite and basalt Thinnest layer of the Earth Mantle Made up of mostly magma Contains convection currents that move the tectonic plates Outer Core Made up of mostly liquid iron and Nickel Gives Earth its magnetic properties Inner Core The densest layer of the Earth Made up of mostly solid iron and Nickel Put the layers of Earth in order from densest to least dense. Crust, Mantle, Inner Core, Outer Core Inner Core, Mantle, Outer Core, Crust Crust, Mantle, Outer Core, Inner Core Inner Core, Outer core, Mantle, Crust Which layer plays the greatest role in the movement of tectonic plates? Crust Mantle Outer Core Inner Core Which two elements are mainly found in the inner and outer core? Fe and Ni Fe and Si Ni and Si Ni and C Why is the inner core solid? Even though it is as hot as the surface of the Sun, it has immense pressure upon it. Iron and Nickel are only solid Because Nickel is not dense Because it is made up of mostly granite and basalt The inner core is about three fourths the size of the ---. Sun Moon Earth United States
