| three layers of the earth | core, mantle, crust |
| the core of the earth is made of ? | metals; iron and nickel |
| what is conduction? | when heat is transferred when objects with different temperatures are in contact. ( a hot pan transfers heat to an egg as it fries) |
| what are the three types of tectonic plate boundaries? | convergent, divergent, and transform |
| what is the engine of plate tectonics? | convection in the earth's mantle leads to sea-floor spreading at divergent boundaries |
| What is a batholith and where can I find one in California? | a batholith is a large mass of cooled magma; yosemite valley is an exposed batholith |
| What are two well-known volcanoes in California and where are they located? | Mount Shasta and Mount Lassen are volcanoes and they are found in the northern part of the state near the Oregon border |
| Where would I go in Hayward to stand on top of the Hayward fault? | Mission Boulevard |
| What are seismic waves? | shock wave sent out by earthquakes |
| How do scientists know what's inside the earth | they measure seismic waves from around the earth; which wave moves through the planet and how long it takes the waves to travel let scientists know that the type of material they are passing through as they pass through the earth |
| Heat and light travels from the Sun to the earth through what type of heat transfer? | Radiation |
| Hot air rising and cold water sinking below warm are examples of what type of heat transfer? | convection |
| source of energy for life on earth comes from what source? | sunlight |
| What's the source of energy for wind? | sunlight heating |
| What causes wind? | earth's atmosphere is unevenly heated by the sun; warm air rising and cold air sinking sets the air in motion. That's wind |
| How many meters are in a kilometer? | one thousand |
| How many centiliters are in a liter? | one hundred |
| A milligram is what fraction of a gram? | one thousandth of a gram |
| What kind of biome is made of large flat grassland and is found in central Asia | steppe |
| What kind of biome is a flat grassland with few trees found in American states such as South Dakota? | plains |
| What kind of biome is a flat grassland with a few trees found in central Africa? | savannah |
| What are three examples of renewable resources? | wind, solar, geothermal |
| What are three examples of non-renewable resources? | coal, natural gas, oil |
| What type of map shows the contours of a landscape? | a topographic map |
| What type of instrument measures atmospheric pressure? | barometer |
| What type of instrument measures the intensity of earthquakes? | seismometer. |
| What are the three basic types of clouds? | Cirrus, stratus, and cumulus |
| What is name for the layer of soil that is dark in color and high in organic matter, which makes it very easy to till and fertilize ground for growing plants? | topsoil |
| What is the layer of the atmosphere where most weather occurs | troposphere |
| What are the two moons of mars | Deimos and Phobos |
| Who was the scientist that discovered that the earth is orbiting around the sun and not the other way around | Galileo |
