Reflection

I thought that this blog a fun thing to do. I liked the idea of doing this blog because we have never done a blog. It is a good resource for anyone who is learning about different energys. I am glad I made this blog because it took me a long time. When we first started making our blog I didn't really know what I was doing, but once you know what you're doing it gets easier. I encourage other people to make a blog for school or anything else because it is a good way to use information. When you do this blog you really have to be a risk taker becauseother people are going to look at you're blog. You have to be a thinker to do a blog because you aren't just magically get information you have to research. You Also have to be an inquirer to do the research.

Geothermal Energy Notes

  • Geothermal energy-is heat deep underground that can produce electricity
  • We will never run out of geothermal energy because it is a renewable energy source
  • Geothermal energy is everywhere underground
  • Geothermal energy has been used for thousands of years
  • The electricity geothermal energy uses is called geothermal power
  • Power plants make electrical power by using energy
  • The word geothermal comes from the words geo meaning Earth and therme meaning heat
  • Gethermal energy is a renewable energy source because the heat is continuosly making this energy in the Earth
  • Magma from the core comes up to the Earth's crust,this is how a volcanoe happens
  • The Earth's crust is in broken pieces called plates
  • Geothermal resvoirs are usually deep underground with no clues that show above ground
  • Geothermal energy can come up in the form of a volcanoe,furmarole,geyser,and hot spring
  • Gethermal activity usually occurs in an area called the "Ring of Fire"
  • Hydrothermal happens when magma comes close to the Earth's surface and heats the ground water that is trapped in porous rock
  • There are three types of power plants called Dry Steam Plants,Flash Steam Plants,and Binary Cycle Power
  • Geothermal energy doesn't pollute the Earth which makes it better for the enviorment

Geothermal Energy Research Questions

Form-What is it like?

What is geothermal energy?Geothermal energy is heat deep underground that can produce electricity.

What is geothermal energy used for?We can use geothermal energy to turn on the lights,heat our house,and preety much everything powered by electricity in our homes.

Function-How does it work?

How do we get geothermal energy?We can get geothermal energy by volcanoes,furmaroles,hot springs, and geysers.

Are there any other ways we can get geothermal energy?Yes,some people dig wells deep into the Earth and geothermal energy gets pumped up usually into power plants that produce energy.

How is geothermal energy made?Geothermal energy is a renewable eneergy source because the heat in the Earth is continuosly making this energy.

Change-How is it changing?

What positive change for the enviorment does geothermal energy have?Geothermal energy uses renewable energy resources rather than nonrenewable energy resources that we might need to use in the future.

Causation-Why is it like this?

How is geothermal energy helpful/useful?Geothermal energy is helpful because whenwe use it we don't need to worry about how much we use.Geothermal energy is useful because power plants use geothermal energy to make electricity that we can use for our house.



Prspective- what are the points of view?

What do other people think about geothermal energy?Most people think that geothermal energy is good because it is a renewable energy source so we will never out.When we use it for electricity it doesn't polute the Earth witch makes it even better.They think that it is better to use a renewable energy source than a nonrenewable energy source.



Reflection-How do we know?

Do we need geothermal energy?We don't need geothermal energy,but without it,it would be hard to live because we wouldn't have any lights,telivisions,airconditioners,and more.

How do we know geothermal energy is a renewable energy source?We know geothermal enegy is a renewable energy source because the Earth is continuosly making this energy.



Connection-How is it connected to other things?

How is geothermal energy connected to our energy topic?Geothermal energy is connected to our energy topic because it makes electricity that uses energy to power things up.

Does geothermal energy rely on other energys?No,geothermal energy doesn' t rely on other energys because it is an alternative energy meaning it can replace other fossil fuels such as oil,coal,and natural gas.



Responsibility-What is our responsibility?

What should we do to conserve geothermal energy?We don't really need to conserve geothermal energy because it is a renewable energy source that doesn't pollute the Earth.It would be goodto find other ways to make electricity just like geothermal energy.
