1. which layers of earth's crust are liquid? solid?
2. What 2 elements make up the Earth's inner and outer core?
3. What is the earth's mantle composed of?
4.What are the convection currents? How do they make the lithospheric plates move?
5. What is the study of the way that lithospheric move called?

1) What are the layers of Earth? There are 4. Once you find out what they are you can look up their properties.
2) Once you learn about the cores you will know what they are made of. Hint: They are heavy.
3) Again, look up the layers. It will be easy to find the composition. You can even use Wikipedia for things like this.
4) Well what is convection? Look it up. Once you understand how it works you will see how it makes the plates move.
5) Well it has to do with the physics of Earth. A prefix used for Earth is geo-.
Learning is about the pursuit of answers. Not about having them handed to you.

1. The crust is solid.
2. Iron/nickel
3. The mantle has a lithosphere and an asthenosphere, the asthensophere is weaker and hotter
Thats all i know of the top of my head. My Geology book is in the garage. Someone will answer more throughly
