Landforms!
This landform is characterized by steep sides and tall peaks. Formed when two tectonic plates collide and push material upwards.
Mountains
-cold temperatures year round
-little precipitation
Polar
natural process of breaking down rocks, soil and minerals when in contact with Earth's atmosphere
Weathering
This is the longest river in the world
Nile River

legend/key
This landform is formed when magma breaches the Earth's crust. Magma becomes Lava once it is exposed to Earth's atmosphere. Lava eventually cools to form new land.
Volcano
-warm summers and moderate winters
-medium levels of precipitation
Temperate
movement of weathered pieces of material to a new location natural things like ice, water, wind, and even living organisms
Erosion
In Ontario, the ___________ basin contains the five great lakes and several rivers.
St. Lawrence River
shows the distance in real life between places on a map
scale
Low land that lays between mountains or higher parts of land. Can be formed by tectonic plate movement, glaciation, and/or erosion.
Valley
-high temperatures year round
-high precipitation year round
Tropical
process of eroded soil being moved by wind, water, ice or gravity to a new location to create a new landform. (Think of islands in a river....)
Deposition
This answer is important for circulating water on a global scale, affects global temperatures, assists shipping, and helps aquatic life migrate
Ocean currents
Alfred Wegener developed the __________ theory that states that all continents on Earth were once one single landform.
Continental Drift
This is landform is formed when extreme erosion and weathering takes off the top of an exposed hill or mountain and flattens what is left behind. Can also be formed by magma that fails to breach the surface of the Earth.
Plateau
-high temperatures year round
-little to no precipitation
Dry
when humans extract natural resources from the Earth's crust and leave a big hole
Mining
This is the most occurring drainage pattern. When rivers flow over rocks, a tree-like pattern will be created into landforms.
Dendritic
The Earth's crust is made up of seven major and several minor _________ that are constantly in motion
Tectonic Plates
This landform is caused by the deposition of sediments at the mouth of a river. This landform is often characterized by rich farm land and soils.
Delta
-hotter summers and colder winters than a temperate zone
-less precipitation that a temperate zone
Continental
the weight and movement of massive ice sheets on the Earth's surface. Ice moves or melts and drags material across surface to alter or form new landforms.
Glaciation
Rainfall changes can have an impact on our environment. State the following:
- It is a human or natural activity?
- How are living things and the environment affected by this?
It is a natural activity. Too much rainfall can cause flooding and loss of habitats. Not enough rainfall can cause drought and can dry out crops.
Islands often form by _____________, when sediments and other materials are carried down a river and dropped once the current slows down.
