Bell ringer (write the question) Write the appropriate label for each letter (use one of the following words Radiation, convection, or conduction) True/false the transfer of heat by direct contact is known as convection True/false radiation is the transfer of heat energy by electromagnetic waves

What are the earth’s spheres?  Everything in Earth's system can be placed into one of five major subsystems: land, water, ice,living things, or air. These five subsystems are called "spheres” Geosphere Hydrosphere Cryosphere Biosphere Atmosphere

What is the geosphere? The mostly solid, rocky part of Earth. It extends from the center of the earth to the surface. Includes Mountains, rocks, soil

Which layer are we located on? The crust

What do we know about water? Water can be a gas, a liquid, or a solid, and can go back and forth from one state to another Water can shape the earth through erosion and deposition

What is the hydrosphere? part of Earth that is liquid water. Oceans, lakes, rivers, marshes, and groundwater

What is the difference between the cryosphere and the hydrosphere? made up of all of the frozen water on Earth. Snow, ice, sea ice, glaciers, ice shelves, icebergs, and frozen ground are all part of the cryosphere Hydrosphere Liquid water on earth

What is the atmosphere? A mixtures of mostly invisible gases that surrounds earth Contains the air we breathe Other parts of the atmosphere cause space debris to burn up before reaching Earth’s surface.

What is the biosphere? The biosphere makes up all the living things on earth Plants, animals, humans, etc.

What spheres do you see in this image

Earth system All of the earth spheres interacting with each other (working together) make up the earth system.

12/06-12/07 (write questions) What is the Atmosphere? What is the biosphere? Which spheres are interacting when a volcano erupts and releases gasses into the air? Emperor penguins spend time on land, and need to breathe oxygen from the air. These penguins also swim and hold their breathe for about 18 minutes as they hunt for fish. How do these organisms interact with each of earth’s sphere? Period 5/7

What is the atmosphere? A mixtures of mostly invisible gases that surrounds earth Contains the air we breathe Other parts of the atmosphere cause space debris to burn up before reaching Earth’s surface.

What is the biosphere? The biosphere makes up all the living things on earth Plants, animals, humans, etc.

How do these organisms interact with each of earth’s sphere? Penguins are living things and belong to the biosphere; they live on the geosphere and the cryosphere; they swim and go hunting in the hydrosphere; they breathe air in the atmosphere.

What is the air composition of the atmosphere? 78% Nitrogen 21% oxygen 1% other gases

What are the layers of the Atmosphere? Troposphere Stratosphere Mesosphere Thermosphere

Which spheres are interacting when a volcano erupts and releases gasses into the air? The Geosphere The volcano The atmosphere The gases in the air released by the volcano. Biosphere Animals having to find shelter due to volcanic eruptions

Troposphere Includes All living organism This is the layer where weather occurs As altitude increases, temperature decreases. clouds

Stratosphere Planes usually fly in this layer Contains ozone The gas molecule responsible for absorbing UV light from the sun Found in the ozone layer

Mesosphere Meteoroids begin to burn up in this layer Coldest layer Due to ice crystals found in this layer Coldest layer As altitude increases temperature decreases

Thermosphere The hottest layer in the atmosphere The northern lights occur in this layer

12/10-12/11write the question Explain the importance of the mesosphere? What would happen to life on earth if the ozone layer was not present? Cloudy nights are often warmer than clear nights. Why do you think that is the case?

Explain the importance of the mesosphere Meteoroids begin to burn up in this layer Coldest layer As altitude increases temperature decreases

What would happen to life on earth if the ozone layer was not present? With no ozone layer, earth will be exposed to more UV rays from the sun

Cloudy nights are often warmer than clear nights Cloudy nights are often warmer than clear nights. Why do you think that is the case? Clouds trap heat

What is the geosphere? The mostly solid, rocky part of Earth. It extends from the center of the earth to the surface. Includes Mountains, rocks, soil

What are the compositional Layers of the earth? Crust The outermost layer of earth Mantle Convection occurs in this layer The middle layer of the earth Core The densest layer Made up of nickel and Iron

What are the two types of crust? Which is denser? Continental Crust Most above sea level Less dense Oceanic crust Located below sea level Denser

What the physical layers of earth? Lithosphere AKA the Crust Mesosphere Upper mantle Asthenosphere Lowe mantle Outer core Liquid layer of the core Inner core Solid densest layer of the core

Lithosphere The lithosphere is made of the crust and the rigid upper part of the mantle The lithosphere is divided into pieces called tectonic plates

Asthenosphere Vs. Mesosphere Upper mantle, weak soft mantle Made up of solid rock Mesosphere Strong lower mantle Rocks flow more slowly in this layer
