Week 2
General Knowledge
Define Mountains, Rivers and LakesList the major mountains, rivers and lakes of
the worldState the differences between rivers and
lakesDifferentiate between the different types of
mountain
Objectives
Mountains are large landforms that stretch above the surrounding land and form a peak. They are steeper than hills and the high elevation causes colder climates than at sea level
Mountains
Types 0f Mountains
Fold Mountains
Block Mountains
Volcanic Mountains
A river is a natural watercourse, usually of fresh water, that flows into the ocean, seas or other rivers. Some rivers flow into the ground or dry up completely.
Rivers
A lake is a body of relatively still water, surrounded by land
Lakes
RiversThey are free
flowing, often in one direction
Rivers have long stretches of land bordering their sides
Rivers flow into the sea
They appear immobile and are referred to as still bodies of water
Lakes are enclosed by land
Lakes evaporate due to heat

Recall
A volcano is a rupture on the crust of a planetary mass object, such as the Earth, which allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
Volcanoes
Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.
How Are Volcanoes Formed?
Active Volcanoes – recently erupted and likely to erupt soon
Dormant Volcanoes- it hasn’t erupted in a long time but there is a possibility that it will erupt in future
Extinct Volcanoes – erupted thousands of years ago and it is not likely to erupt again.
