Earth's Features/Weathering & Erosion
Where do earthquakes typically occur on a map?
They occur in bands and are found near the edges of a continent along the ocean.
Is there more saltwater or freshwater on earth?
Saltwater-ocean
What would happen if the atmosphere or Hydrosphere disappeared?
The biosphere (all living things) would not be able to exist without these two spheres.
What causes a flood to occur?
Rain, Hurricanes, Ice/snow, dam failure
Explain what the key or legend is for on a map.
It explains the colors, lines, symbols on a map allowing observers to understand the meaning/purpose of the map.
List 2 things that cause weathering and erosion to occur?
Wind, freezing, gravity, natural disasters, sun, rain, and snow.
List 2 types of fresh water sources.
open lake, spring/groundwater, glaciers, snow run off, rain water, etc.
Give me an example of how two different spheres interact with each other.
How does a flood majorly affect a community?
Costly damage, lengthy time to recover, animal/human loss.
Sing the 3 states of matter song.
First we have our solid, then we have our liquid, don't forget what's last that's our gas.
Draw a model of a rock that has been weathered and explain.
The rock can have a split, breakage, or chiseling.
What particles do rivers bring into lakes or the ocean?
Salt and minerals
Sing Earth's 4 Spheres song with the actions.
Atmosphere, Hydrosphere, Biosphere, G-O- SPHERE!
Give me an example of the damage a flood can cause to a home?
Examples: carpet, drywall, landscape, etc.
When reading a graph what are the key things we should look for? Give me 3 specific items.
Which states are more likely to have an earthquake?
Example: California, Washington, Oregon, etc.
Draw a picture of a closed (terminal) lake, and explain if it will contain salt or freshwater.
Salt water, rivers bring salt and minerals to the lake and there is no way out to help filter the salt. The drawing should be circular with a river flowing in, but no way out.
Have 4 students from your group be a standing actor/actress to represent each sphere.
All 4 spheres need to be represented
What type of structure can we make to help reduce the affects of floods?
Examples: dams, sandbags, diverging water, etc.
What is a phenomenon?
The object or idea in question. We then observe and collect data to determine if the phenomenon is accurate.
Sing the weathering and erosion song, and do the actions.
Weather breaks it, Erosion Takes it
The ocean covers what percentage of earth's surface and is it salt or freshwater?
approximately 71%- saltwater
Give an example of items that belong in each sphere (1 example for each sphere, 4 total).
Hydrosphere- water
Biosphere- living things
Atmosphere- air/gases
Geosphere- land forms, rocks, etc.
Sing the water cycle song, along with the actions.
Evaporation, Condensation, Precipitation is when it pours.
Tell me the scientific method. (6-7 steps)
1. Ask a question
2. For a hypothesis
3. Experiment
4. Collect data
5. Analyze
6 . Conclude
7. Report
