Learning Targets
1. Investigate the layers of the Earth and compare their compositions, thickness and distinguishing characteristics that affect surface phenomena and have human impact.

1. Label as many layers of the Earth as you can.

2. Using this image, infer how radioactive decay is related to the heat within the Earth.

Crust, mantel, outer core, inner core

1) Crust, Mantle, Outer Core, Inner Core
2) When the rocks inside the Earth start to decay, they heat up at the same time. So the heat from within the Earth come from the radioactive decay of rocks.

1.)Crust, Mantle, Inner Core and Outer Core.
2.) radiomatic decay in the earth will create heat which heats the earth

I agree with da drake steele

1. Crust( top layer) mantle( second layer) outer core (third layer) inner core made of molten iron and nickel( last layer)
2. Radioactive decay causes heat by the fission(splitting) of atoms nuclei due to the friction caused by bombarding atoms.

1.Crust,Outer Mantle, Inner Mantle, Outer Core, Inner Core
2. Core is the oldest so it has decayed more which means that it is hotter because it released more heat.

1:core, outer layer, inter core, mantle.
2: the earth will create heat that will heat the earth so we will not have another ice age. I think my answer is wrong

1.)Crust, mantle,outer core, and inter core.
2.) cause the atoms in the core are unstable

So it's really hot

Brandon Handley

1.) the atmosphere, the lithosphere, the mantle, outer core, and inner core.
2.) when radioactive decay happens it gives of heat.

1) atmosphere lithospher outer core inner core 2) it creates heat

Haley Jo

1- crust, core, mantle, outer core, inner core
2- when a parent isotope combines with radioactive decay, it produces her and when there is heat it produces a baby.. aka a daughter.

i meant to say it produces *heat*

Cameron Paynter

Crust mantle outercore inner core
When radio active decay happens

Jonathan Hernandez

1,atmosphere
2, it gives off heat

Mailen Burnett

2/20/2013 09:32:51 pm

1) crust, mantle, inner core, outer core.
2) it creates heat which helps heat up the Earth?

Luke Yantz

From inside to outside-
1. Inner core
2. Outer core
3. Inner mantle
4. Outer mantle
5. Crust
6. Atmosphere

Question 2
Radioactive decay generates heat, so when it dies, it creates a daughter isotope and heat output

Ignore number two and I think it it increases the level of heat that is in the inner most parts of the earth

Kassidy Tingle

2/20/2013 09:34:07 pm

Inner core, outer core, inner mantle, outer mantle, crust, atmosphere

Michelle

2/20/2013 09:35:17 pm

#1.Crust,Outer Mantle, Inner Mantle, Outer Core, Inner Core
#2. Core is the oldest and decayed more which means that it is hotter because it released more heat

Adam fisher

1 inner core
2 outer core
3inner mantle
4 outer mantle
5 crus

Veyda

1)Crust, inner core , outer core, mantel outer mantle, mantle
2) when it decays it gives off heat like the earth

Gjuraj O'Nan

2/20/2013 09:36:43 pm

1-crust, core, mantel, outer core
2-it genorates heat

Fernando Smither

2/20/2013 09:36:58 pm

1.) atmosphere, outer core, inner core, inner mantel, outer mantel, crust
2.) it gives off heat

Jenna Jo

2/20/2013 09:37:11 pm

1-Inner core, outer core, inner mantle, outer mantle, crust, atmosphere
2-it generates heat

Dylan Mayer

1.)inner core, outer core, mantle, crust, lithosphere, and the atmosphere.
2.)when the radioactive decay happens and gives off heat.

Gracie Mahoney/ Alyssa Nichols

1. Crust, inter core, outer core, mantel
2. Radioactive decay is when it gives off heat.

Alek

2/20/2013 11:16:18 pm

1. Inner core , outer core , mantle, crust
2. Radioactive decay is caused by the bombarding of new atoms causing an unbalanced amount of protons and neutrons

Tanner

2/20/2013 11:16:37 pm

1) Inner core, outer core, inner mantle, outer mantle, crust
2) Radioactive decay puts off heat

Aleah tuggle

-inside to outside-
1. Inner core, outer core, inner mantle, outer mantle, crust, atmosphere
2. It generates heat.

Emily

2/20/2013 11:17:03 pm

1. Inner core, outer core, mantle, crust.
2. When rocks decay in the earth it gives off heat, so the heat from within the earth comes from the radioactive decay.
