challenges caused by earth's forces
The ring of fire (the earthquake zone) is located in what ocean?
The Pacific Ocean
A _____ is a mountainous landform through which fluid and semi-fluid material escapes
volcano
What affects the moisture level of the soil? (hint: 2 factors)
Precipitation and evaporation
plate tectonics is the theory that the earth is made out of these
Plates
In what way are greenhouse gasses good?
Greenhouse gases help us stay warm by trapping the sun's heat, without it the heat would not be contained
how do we classify the size of an earthquake
Richter scale
Magma, a material found in the core of the earth turns into ___ after it reaches the Earth's surface
Lava
an area or region beyond which trees don't grow
treeline
When a divergent plate boundary occurs, the plates do this
Separate/move away from each other
what are the 2 ways of dealing with climate change
Mitigation, and adaptation
When an earthquake occurs, shockwaves shake the land the ____ is the place on earth's surface directly above where the main shock occurs
Epicenter
What are the different types of landforms (hint: there are 5)
mountains, shields, valleys, plains, and plateaus.
what are the 3 natural factors that influence vegetation
Moisture, temperature, and soil
the Earth's plates can move in 3 different ways
they can separate/move away from each other, grind past each other, and push/crash into each other
What is a natural cause of climate change (hint: 2 possible answers)
sometimes we get more energy from the sun than normal, the Earth's axis ranges from 22-25 degrees so the earth tilts to and away from the sun
How do scientists measure the size of an earthquake?
Seismograph
What is the largest landform in Canada?
Shield/Canadian Shield
Regions that have higher temperatures are at risk of this affect causing limited plant growth?
Evaporation
The Earth's plates move constantly this is caused by this
Convection flows
What are 3 greenhouse gasses
co2 , methane, and ozone
What can cause damage during a volcano eruption (hint: 4 factors)?
Hot gasses, ash, rocks, and lava
What is the most common type of mountain
fold mountains
This is full of nutrients, and is essential to plant growth
Humus
The Earth's plates float on this
asthenosphere
Name 2 out of the 6 major human activities that produce greenhouse gasses
1. ENERGY PRODUCTION 2. TRANSPORTATION 3. INDUSTRY 4. HOMES/BUSINESSES 5. AGRICULTURE 6. WASTE
