1. What are characteristics of mountains
|
Mountains are usually above sea level.
|
|
|
rivers
|
Rivers tend to run in one direction
|
|
|
oceans
|
oceans are big bodies of saltwater and some freshwater.
|
|
|
valleys
|
Valleys lie at sea level and tend to be between mountains
|
|
|
local landforms
|
They are created by forces of nature such as wind, water and ice.
|
|
|
How does weather change from day to day and between seasons?
|
Seasonal weather change is the result of the tilt of the Earth’s axis causing more direct sunlight to face the various hemispheres. Daily weather changes are the result of temperature differences caused by differences in solar absorption and atmospheric changes resulting in wind and resulting moisture variations.
|
|
|
Which of Earth’s resources are used in everyday life and how can they be conserved?
|
Some of many of earth’s resources include energy, water, air, wood, oil and minerals. Most can be better preserved through developing new technologies for alternative fuels and energy resources, and by developing better habits for conservation of natural resources.
|
|
|
What simple tools are used to measure weather conditions from day to day and across the seasons?
|
Simple tools used for measuring weather conditions include anemometer (speed and direction of wind) thermometer (for measuring temperature) hygrometer (measures relative humidity) barometer (determines atmospheric pressure changes) and a rain guage (measures rainfall).
|
|
|
How does weather change from day to day and what are seasonal trends?
|
Wind direction moves air masses and brings weather with it. Air from the ocean brings humid air, air from the desert moves dry air, polar air is cold. These air masses contain various temperatures and moisture content which result in pressure systems and cause daily weather changes. Seasonal trends tend to be predictable based on the tilt of the Earth’s axis as the Earth travels around the sun on its yearly path.

|
|
6. How do we know that the sun warms the land, air, and water?
|
The sunlight warms the land, water, and air and in return the land, water and air give off heat, which rises up in the atmosphere causing pressure changes which create weather systems. The Earth’s atmospheric gases capture the heat and prevent it from escaping. The trapped heat keeps the ground, oceans and air at stable temperatures.
|
|
|
7. What are some of the different properties of rocks?
|
Properties of rocks include chemical composition, hardness, color, streak, specific gravity, fracture, and luster.
|
|
|
8. Where do smaller rocks come from?
|
Smaller rocks come from the erosion of larger rocks as the result of weather, running water, ice, etc.
|
|
|
9. What is soil made of and how do soils differ?
|
Soil is made up on weathered rock, water, air and organic materials and they differ due to their varying chemical and physical properties. These properties are affected by the nature of the parent rocks, human influences on the area, and the varying amounts of sand, clay and silt in the area.
|
|
|
10. Fossils provide evidence of what?
|
Fossils provide evidence about plants and animals from long ago
and offer clues about the history of Earth. |
|
|
11. What resources (food, fuel and building materials) do rock, water, plants and soil provide?
|
All of these resources promote and sustain food which humans need to survive. Organic materials provide fuel in the form of coal and both hydroelectric and biofuels provide alternative sources of energy. Both rocks and wood (especially in rich fertile soil) provide building materials for humans.
