Space
What is the difference between a meteorite and meteoroid?
Meteorite hits earth
Largest landforms visible from space
Continents
Name the three layers of the earth from outermost to innermost.
Crust, mantle, core
What is the difference between erosion and weathering?
Erosion wears away Earth's surface, weathering breaks down rocks
Oceans, rivers, lakes, and other water bodies make up this part of the Earth
Hydrosphere
Name the four gas giant planets.
Jupiter, Saturn, Uranus, Neptune
The name of the supercontinent before continental drift
Pangea
Mountains and volcanoes are formed by this process, where the oceanic plate goes under the continental plate.
Subduction
Main difference between chemical and physical weathering.
Chemical weathering changes makeup of rocks, physical just breaks rock into smaller pieces
What percent of the earth's freshwater is in groundwater?
95 percent
What are the differences between comets and asteroids?
Composition
The lowest and highest dry land points on the earth
Dead Sea, Mount Everest
Land is pushed apart by this process, where two oceanic plates pull apart
Spreading
Three types of erosion
Wind, glacial, water
Most of Earth's water is in oceans. What expensive process makes this water drinkable for humans?
Desalination
What are the characteristics of a terrestrial planet?
Solid surface, rocky core, plate tectonics
The underwater extension of the coastal plain
Continental shelf
This zone has lots of fault lines, so there are lots of earthquakes and volcanoes here.
Ring of Fire
What are glaciers and how do they erode the Earth?
Giant bodies of ice, they move downhill and pick up rocks and soil
Name three major water issues we discussed in class yesterday.
Glacier melt
Lake Chad shrinking
Groundwater contamination
Extreme precipitation
Why are some days longer and shorter than Earth days on other planets?
Speed of rotation as they orbit around the sun, time it takes to orbit the sun, distance from Sun
Manmade strip of land connecting North and South America
Isthmus of Panama
How were the Hawaiian islands formed?
Moving plate passed over a hot spot, magma and rock pushes through Earth's surface (Subduction and volcanoes)
What is a moraine?
The pile of rock and debris a glacier leaves behind
Describe the water cycle.
Evaporation, condensation, precipitation, runoff, groundwater
