Science Praxis 5005 Elementary
Education
Plate tectonics - answer Movement of continents and changes in the Earth's crust
caused by internal forces
Atmosphere – answer dry gas (nitrogen, oxygen, argon carbon dioxide), water vapor,
solid particles
Troposphere - answer closest to Earth's surface (weather related activities)
Stratosphere – answer Very little water, ozone layer
Mesosphere – answer Coldest layer
Thermosphere - answerLayer extends upward into space
Mountains are caused by... - answervolcanic action or tectonic plate collisions
Folding - answerfolding of rock layers, usually sedimentary rocks
Faulting - answerFractures in Earth's crust because of tension
Volcanoes are... - answerthe movement of magma through the crust and its emergence
as lava onto the Earth's surface
Active, Dormant, Extinct, and volcanoes - answercurrently/building up to an eruption,
between eruptions but internal activity, and no longer erupting
Igneous rock formation - answerIntrusive: formed below Earth's surface. Extrusive:
formed at Earth's surface
Sedimentary Rocks - answercreated when fluid sediments are transformed into solid
rocks. Cementation is when sediments are converted to sedimentary rocks
Igneous Rocks - answerclassified according to their texture, composition, and the way
they formed. Made from magma (molten Rock)
Metamorphic rocks - answerformed by high temperatures and great pressure. Process
is called metamorphism.
, Minerals - answernatural, nonliving solids with a defined chemical composition and
crystalline structure
Glaciers - answerbodies of ice that move over the land due to gravity.
Fossil - answerremains or trace of an ancient organism
Erosion - answertransportation of surface materials by another moveable material
(water, wind, ice)
Deposition - answerAKA Sedimentation, process by which material from one area is
slowly deposited into another area. result of matter being eroded.
Weathering - answerbreaking down of rocks at or near the Earth's Surface
The several eras - answerprecambrain (no life), paleozoic (continents and sea animals),
Mesozoic (reptiles, new landforms), Cenozoic (ice age, mammals, humans evolving)
Stratigraphy - answerprocess of determining the age of rocks
Absolute Dating - answerthe use of radioactivity to determine Earth's age
Planets - answerMercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune
Mercury - answerClosest planet to the sun
Jupiter - answerLargest planet in the Solar System
Uranus - answerThird largest planet - gaseous planet
Pluto - answerdwarf planet
Sun: The Core - answerinner portion of the sun - fusion takes place
Sun: photosphere - answersurface of the sun, produces sunspots
Sun: chromosphere - answerHydrogen gas causes this portion to be red
Sun: The corona - answerThe transparent area of the sun visible only during a total
eclipse.
Stars - answera ball of hot, glowing gas that is hot enough and dense enough to trigger
nuclear reactions.
How do astronomers measure the brightness of a star? - answerastronomers measure
the brightness of a star by measuring its magnitude.
