Earth's Layers
Plate Tectonics
Convection Currents
Plate Boundaries
Layers of Solid Earth
100
Which layer of the Earth is solid and why?
The Inner core is solid because of the high pressure and temperatures.
100
What is plate tectonics?
Theory that earth's outer core shell is divided into several plates that glide over the mantle.
100
How can you tell the temperature of convection currents?
An example of how You can the temperature of convection currents is because when land mass is contagious to a body of water during the day it causes a sea breeze.
100
What are the three plate tectonic boundaries?
divergent,convergent, transform plate boundaries,
100
What are the four layers of solid earth?
The layers of solid earth is made up of layers which are called the crust, mantle, inner core, outer core
200
What is the earth's layers? Hint ( there are four separated layers that are in the earth)
crust, mantle,outer core, inner core
200
who created the plate tectonics? 
Alfred Wegener

What is a convection current?
A convection current is when heat is being transferred from one place to another by mass motion of a fluid. For example like water, air or molten rock.
200
How are plate boundaries created?
Plate boundaries are created by the earth's crust being broken into plates that move around relative to each other.
200
This layer makes up the largest volume of the Earth.
The Mantle
300
Which layers make up the asthenosphere?
The bottom part of the upper mantle
300
How long does it take for earth's plate tectonics to form?
It takes about 1 billion years to form
300
How are convection currents made?
Convection currents are made by magma drive plate tectonics.
300
How are plate boundaries formed?
Plate boundaries are formed by Divergent, Convergent, and transform boundaries.
300
The solid, dense center of Earth, mostly iron and nickel, kept solid by extreme pressure.
Response: What is the inner core?
400
The part of the mantle called the blank which is made up of a soft rock that bends like plastic.
asthenosphere
400
How do plate tectonic plates move?and how fast do they grow?
Tectonic plates move because of the intense heat in the earth's core that causes molten rock in the mantle layer to move. Tectonic plates grow about 1 to 2 inches per year which is about the same speed as your fingernails grow.
400
How are convection currents caused?
convection currents are caused by an uneven temperature within something.

What would happen if two tectonic plates collide?
When two tectonic plates collide (a **convergent boundary**), several things can happen depending on the types of plates involved:
- 🔹 If **two continental plates** collide, they crumple and push upward, forming **mountain ranges** (e.g., the Himalayas).
- 🔹 If an **oceanic plate and a continental plate** collide, the denser oceanic plate is forced under the continental plate in a process called **subduction**, which can create **volcanoes** and **deep ocean trenches**.
- 🔹 If **two oceanic plates** collide, one is pushed under the other, forming **volcanic island arcs** and deep trenches.
These collisions also generate powerful **earthquakes** due to the intense pressure and friction where the plates meet.
They would form into a convergent plate boundary. if the converging plates move beneath the other that is known as subduction.

This rigid layer includes the crust and the uppermost mantle, and it’s broken into tectonic plates.
Response: What is the lithosphere?
500
What best describes the earth's layers which makes up the asthenosphere.
The rigid lithosphere best describes the earth's layers which makes up the asthenosphere because it floats or moves on the slowly flowing asthenosphere which creates the movement of tectonic plates.
500
How are tectonic plates able to move?
Tectonic plates are able to move because the earth's lithosphere has a greater underlying asthenosphere.
500
How are convection currents important to the earth system?
the reason why convection currents are important to the earth system is because without convection currents and the magma there would be nothing to drag the plate tectonics.
500
Why do the plates collide? and how do they collide?
plates collide because they are moving on a spherical surface. Plates collide when two plates are carrying continents collide. when this happens the continental crust carries and rocks pile up which creates towering mountain ranges.
500
Why is the inner core solid while the outer core is liquid?
the reason why the inner core is solid is because it is 50 time stronger than the magnetic field at the surface. But the outer core is liquid and not solid is because it is not under enough pressure to be solid so it is liquid even though it has a composition similar to the inner core.
