Geography-plate boundaries+tectonics

Question 1

What layer of the earth is liquid and made up largely of iron

Answer 1

The outer core

Question 2

Describe the mantle

Answer 2

The mantle is the thickest structure of the earths core were temperatures can range from 1,300, near the crust and 5,500 near the inner core

Question 3

Which layer of the core is very thin ranging from 6-70km

Answer 3

The crust

Question 4

True or false

A conservative plate boundary occurs when plates slide past eachother in the same or opposite directions at different speeds. Friction between the plates is eventually overcome and the plates slide past each other in a sudden movement, this triggers earthquakes

Answer 4

True

Question 5

What happens at a constructive plate boundary

Answer 5

When plates move apart volcanoes form as magma wells up to fill the gap, and a new crust is formed

Question 6

What part of the earth is the hottest

Answer 6

The inner core is the hottest part of the earth it is usually around 5,500degreescelcius and it is made out dof lots of metals
