or
Maps are pictures of the Earth that are much smaller than the real life places they show.
what is migration?
the movement of people from one area within a country or from one country.
the blank is made up of rocks from two of the earth major layers.
lithosphere
it refers to the movement of molten rocks which lies within the earth crust.
volcanic activity
What is a volcano?
A volcano is a natural vent or fissure in the Earths crust .
it is used on a map to measure distance.
What is a scale
two categories why people migrate
push and pull factors
what are earths two major layers?
the crust and the mantle
the process by which liquid rocks or magma is forced through vents into the Earths crust or onto its surface.
volcanism
the two geological and physically related phenomena.
earthquakes and volcanoes
Three Main types of map scales?
1. word scales
2. linear scale/ bar scale
3. representative scale
the movement from one region to another region for the purposes of seeking employment or improved financial position.
economic migration
the three main types of rocks which forms the earth lithosphere.
Igneous
Sedimentary
Metamorphic
Volcanic activity are of three natures. what are they
active
dormant
extinct
the large chamber beneath a volcano is called
What is magma chamber
It uses a line or bar to show relationship between map distances and real life distances.
linear/ bar scale
the movement of people from the country side to the towns and cities.

what are intrusive rocks and give an example of it.

False
which type of igneous rock are formed after an eruption and are cooled and solidifies.
extrusive
which plate tectonics causes a volcano to form and explain how this process is done.
Volcanoes are formed by colliding plates in a zone of convergence or subduction. Where convergence is taking place. one of the crustal plates descends in the subduction zone. The rocks melt as they are heated and the molten rocks is forced upwards erupting as a volcano.
