What makes a resource nonrenewable?
Is the grand canyon formed by:
glaciers scraping earth's surface?
OR
erosion by wind and water?
The grand canyon is formed by wind and water eroding the the land to form the canyon.
List three nonrenewable resources.
coal, oil, and natural gas.
If you find a fossil of a land plant in a layer right above a layer of sea shell fossils, what can you conclude?
The environment changed over time from being an aquatic environment to a terrestrial environment.
What is the sun's role in the water cycle?
It provides the energy to heat up the water and causes it to evaporate.
What is different about the water cycle near a lake vs. the water cycle near the ocean?
The ocean provides more water to be evaporated which can lead to increased precipitation.
What would causes a sharp jagged mountain to be worn down over time so that it is smooth?
WEATHERING!
What is the main source of energy for the water cycle?
The sun.
The one on the top. (Law of Superposition)
Draw a model of the layers of the earth.
Thin crust, mantle, outer core, inner core.
The ______________ (more or less) mass an object has the more gravity it will have.
More. More mass equals more gravity.
Describe three different ways that a rock could be weathered, one way MUST include ice.
1. Water gets into cracks in the rock and expands when it freezes into ice, breaking the rock.
2. Wind blasts rocks with small pieces of sand/sediment wearing them smooth over time.
3. Water wears down rocks over time.
In a parallel circuit, what happens if one of the bulbs burns out?
The rest remain lit because they each have their own path of electricity.
What is the process for the formation of sedimentary rock?
Small pieces of rocks are pressed and cemented together into layers, usually at the bottom of the ocean.
What happens BETWEEN evaporation and precipitation in the water cycle?
Give an example of weather and an example of climate.
Weather: It is going to rain tomorrow
Climate: It is usually cold in Michigan during the winter.
Describe the types of landforms modeled in a stream table.
1. A river
2. Delta
3. Ocean
There is a series circuit with three bulbs and a switch. If the wire is cut, how many of the bulbs will remain lit?
NONE! There is no complete path of electricity!
What can scientists determine by studying the fossil record?
The way the earth (weather, climate, and animals) have changed over time.
Weather is sudden changes and climate describes the average weather over a long period of time (many years).
Where do the water droplets on the outside of a cup come from.
Condensation from water vapor.
List TWO ways that earth's surface changes rapidly.
- Earthquakes
-Landslides
Insulation.
Partially decayed plants are buried with sediment over time. The sediment creates pressure as it gets buried deep under the ground. What nonrenewable resource may eventually form from this scenario.
Coal.
What type of soil retains water, is dark brown, and feels soft?
(hint: clay, silt, loam, or sand)
Loam.
