Climate and Weather
What is the difference between climate and weather?
Day to day conditions in the atmosphere vs. average conditions over 1 year.
Explain biological weathering and give an example.
Breakdown of rock by living things.
Tree roots, animals borrowing
Which country has the most glaciers?
Canada
Name 3 of Canada's Biomes.
Mixed Forest - Tundra
Grassland - Desert (pocket)
West Coast
Boreal
What are the 3 types of rocks?
Igneous
Metamorphic
Sedimentary
The E in LOWERN stands for?
Elevation
Freeze-thaw is a type of...
Physical/Mechanical Weathering
Why do environmentalists use glaciers to explain climate change?
They melt and are easy to measure.
Where are most volcanoes located in Canada and why?
Pacific coast - on the pacific ring of fire tectonic plates
Explain the difference between intrusive and extrusive rock?
Intrusive - Forms INSIDE the Earth
Magma cools slowly underground -cGranite
Extrusive Rock - Forms OUTSIDE the Earth
Lava cools quickly on the surface - Obsidian or Basalt
Explain Latitude in relation to LOWERN.
How close a place is to the equator because it is closest to the sun.
Give me an example of chemical weathering.
Acid rain dissolving limestone.
Oxidization - rust
Give 2 examples of land features created by glaciers?
Esker - valleys - glacial lakes
Moraine - Till
Erratic - Misfit
Drumlins
What are 3 ways to protect yourself during an earthquake?
Get under a table
Stay away from windows
Stay out in open/away from buildings
How is sedimentary rock formed? Give an example.
Formed from sediment (sand, silt, shells, fossils) that is deposited, compacted, and cemented.
Sandstone, limestone
How do winds and air masses affect temperature?
Wind brings different temperatures
Give me an example of water erosion.
Streams carrying sediment
Waves pushing sediment.
Rainwater in ditches carrying leaves/rocks, etc.
What's the difference between an alpine glacier and a continental glacier?
Alpine - smaller glaciers move down mountains carving out valleys
Continental - giant ice sheets/blankets that cover large areas.
Where are tornadoes most likely to occur in Canada and why?
Southern prairies
Warm, moist air from the south meets cold, dry air from the north
Flat
Marble is a type of what rock?
Metamorphic
Explain Relief (LOWERN)
Mountains affect rain and temperature
Sand dune (Wind)
Delta (Water)
Moraine (ice)
Give 2 ways melting glaciers effect the earth.
Changing salt level - ruins habitats
floods
rising sea level
Explain one biome and give 3 points.
Various
How can sedimentary rock become an igneous rock?
It is buried and melts into magma.
