Greenhouse gases are are gases that live in the earth's atmosphere and trap's heat in the earth's atmosphere.

Volcanoes
-
Volcanos are created from divergent boundaries because when the tectonic plates split hot magma will rise out from the earth, once the magma cools there will be a massive rock that looks like a mountain and the volcano
There are different types of volcanoes: Active volcanoes, Dormant volcanoes and Extinct volcanoes.
-
Dormant volcanoes: Dormant volcanoes are volcanoes that are not erupting at this time but could erupt any time.
Extinct volcanoes: Volcanoes that have stooped erupting lava and a little bit of magma is left in the volcano but the volcano has just transformed int a mount
Volcanoes erupt when the magma chamber is full and once the magma chamber is full, the magma will be forced and pushed up and that is when the magma comes out of the volcano and the magma becomes lava.
Some volcanoes can go extinct when the volcano does a huge eruption and explosion and if that happens all the magma comes out, where there is no magma left, the volcano becomes a mountain.
Water
Evaporation is when water turns into gas by the sun's heat so from water the heat separates the molecules in the water which make the water smaller. For example from a huge puddle of water it takes hours and hours for the water to evaporate because the heat can take a very long process to get all the water turned into a gas and the sun's heat can’t make water evaporate in a second.
-
The water cycle is when a place rains and once the rain is done the water is left on the ground, from the ground the water is evaporated and is moved into the cloud so then it rains again.
The oxygen cycle is when the oxygen in the atmosphere comes down and becomes carbon dioxide and then it is made again by green plants photosynthesis.
The carbon cycle is carbon that is from the atmosphere comes down and travels back up.
Atmosphere
An atmosphere is the outside of a planet. It is created by different levels of gases: troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
exosphere: The exosphere is the last layer of gas located at the end of the atmosphere.The exosphere is filled up with element like hydrogen, helium and other molecules in the layer that have nitrogen, oxygen, and carbon dioxide
Thermosphere: The thermosphere is located in between the exosphere and the mesosphere. The thermosphere is filled up with elements like
Mesosphere: The mesosphere is located in between the Thermosphere and the stratosphere. The elements that are found in this layer is iron, magnesium, calcium, sodium and potassium.
Stratosphere: the stratosphere is located in between the mesosphere and the troposphere. The elements that are found in the stratosphere is nitrogen and oxygen.
Troposphere: The troposphere is located below the stratosphere. The elements that are found in the troposphere is oxygen, nitrogen, argon, water vapour and carbon dioxide.
In the middle of the troposphere and the stratosphere, there is a layer of gas called the ozone layer. The ozone layer is filled with elements like chlorine, carbon and fluorine. The ozone layer helps Earth by protecting the sun's UV rays against Earth without the ozone layer any living thing could not survive or even live.
Earth
The earth is created from four different layers that are made up of rocks and magma: The crust, mantle, asthenosphere and core.
Core: The core is made out of magma. The core is the heart of the earth, without the core we could not live on earth.
Asthenosphere:The asthenosphere is located in between the outer core and he mantle. This layer is quite heard to be at because on this layer it is quite hot because it is very close ti the core of the earth and if any person tried to walk or try to be at the asthenosphere they could get burnt in 10 seconds.
Mantle, the layer that is in between the asthenosphere and the crust. The mantle would be the biggest layer of rocks in the earth than the other rocks. The mantle is filled with different varieties of rocks.
Crust: The layer of rock located at the earth's surface. The crust is not as hot as the other layers due to the other layers being closer to the core of the earth. The crust layer is not the hardest rock layer in the earth and it is the softest layer because it is filled with soil.
The earth is filled up with different rocks: sedimentary, igneous and metamorphic rocks.
-
sedimentary rock: Sedimentary rocks are very ancient rocks or once living organisms that were combined to make sedimentary rocks and sedimentary rocks can be found in famous landmarks.
Metamorphic rocks: Metamorphic rocks are rocks that were sedimentary, igneous or earlier metamorphic rocks and have changed overtime from their original form.
Continental drift
Continental drift is when continents start to drift over time by the movement of tectonic plates. There are three different types of plate boundaries : divergent, convergent and transform plate boundaries
-
-
-
Continental drifts happens when the ocean gets bigger the continents start to break apart from each other.
On earth there was a super continent that was called Pangea as the oceans stated to grow bigger continents started to separate and then the continents are at there place as they are now.
-
There are two machines that scientists have created to measure an earthquake a Richter scale and a seismograph.
-
The richter scale: A Richter scale is when a machine measures the amount of magnitude from an earthquake.
