Earth Outer Layers
This is the name of the layer that is composed of the crust and the uppermost part of the mantle.
What is the lithosphere?
This is the most dense layer of Earth.
What is the inner core?
This is the layer of the atmosphere that weather occurs in.
What is the troposphere?
This is the earth sphere includes things like the ocean, lakes, and rivers.
What is the hydrosphere?
Earth has ____ main layers and the _______ is the coolest (lowest temperature) layer.
What is 4 and crust?
This is the type of crust that is considered to be thin, young, and dense.
What is the oceanic crust?
These are the two layers made mostly of iron and nickel.
What are the inner and outer cores?
This is the layer that contains the International Space Station.
What is the thermosphere?
This earth sphere includes things like mountains, volcanoes, canyons, and trenches.
What is the geosphere?
This layer of the atmosphere is the coldest.
What is the mesosphere?
This is the layer that is split into tectonic plates.
What is the lithosphere?
List 3 properties of the outer core.
Liquid (molten), made of iron/nickel, responsible for the magnetic field, 4,400 - 5,000 degrees Celcius, 5,100km deep.
The ozone layer is here.
What is the stratosphere?
During a period of extensive storming regions experience mudslides. These are the two earth spheres interacting.
What is the atmosphere and the geosphere?
This earth sphere includes organisms like bacteria and fungi like mushrooms.
What is the biosphere?
This layer is right below the lithosphere and its movement contributes to continental drift.
What is the asthenosphere?
The mantle is the ___________ layer and is made of hot solid _______.
What is thickest layer and hot solid rock?
This is the coldest layer of the atmosphere.
What is the mesosphere?
During a wildfire, large areas or forestry are burned and many ecosystems are disrupted with smoke filling the air. These are the two spheres interacting.
What are the biosphere and the atmosphere?
During an volcanic eruption, the lithosphere opens and allows molten rock from below to rise up where is cools and hardens. This new crust is nutrient rich and will be a great place for plants to grow.
These two spheres are interacting here.
What are the geosphere and the biosphere?
The heat in the mantle has movement that rises and falls called ___________ ___________.
What is convection currents?
The inner and outer cores are both made of _____ and _______. The outer core is so hot it is _______ but the inner core is _______ even though it is hotter, due to high pressure.
What is iron, nickel, liquid/molten, and solid?
These are the atmosphere layers in order from most dense to least dense.
Bonus if you can state the mnemonic to help remember it.
What is troposphere, stratosphere, mesosphere, thermosphere, and exosphere?
Mnemonic - Three Silly Monkeys Throw Excrement
The furthest a human has been able to drill into the earth was about 12 km. They stopped in the ______ layer. They could not go further due to extreme ______ and ________ making it too difficult to continue.
What is the crust, heat and pressure?
List the layers of the earth AND atmosphere in order from LEAST dense to MOST dense.
What is exosphere, thermosphere, mesosphere, stratosphere, troposphere, crust, mantle, outer core, and inner core?
