tectonic and climatic

Question 3

tropical storms, flooding, extreme weather, lighting

Question 5

Answer 5

by causing harm to people, buildings, roads or railways

Question 6

what force push continents around

Answer 6

convection currents

Question 7

two human developments that would increase the risk of people being affected by natural hazards

Answer 7

quality of materials and structure of building
poor roads and lack of routes

Question 8

how do convection currents work

Answer 8

Heat from the core makes magma in the mantle rise towards the crust. As the hot current nears the crust, it begins to cool and sink back towards the core. As the magma sinks, it drags the plates across the surface of the Earth.

Question 9

what are the 4 layers of the Eartha and what order are they in

Answer 9

1. crust-thinnest-solid
2. mantle-biggest-magma-semi liquid
3. outer core-liquid
4. inner core- solid-hottest

Question 10

what is ridge pull

Answer 10

ridge pull is when convection currents push apart the plates

Question 11

what is slap pull

Answer 11

when the denser plates sink back into the mantle under the influence of gravity which pulls the rest of the plate along behind it
