Geography:Chapter 2

Section 2: Land, Air, and Water

plate a huge block of Earth's crust
weathering a process that breaks down rocks into small pieces
Things that cuase weathering ice, wind, rain, living things (lichens)
Ring of Fire Around the rim of the Pacific Ocean where there is a string of volcanoes and earthquakes. 80% of the world's active volcanoes and earthquakes occur at this ring.
atmosphere The layer of gases, including oxygen, that surrounds our Earth. It is needed for life to exist here.
more than 70% This is the amount of the Earth that is water; lakes, rivers, seas, oceans.
landforms Shapes and types of land
mountains Rise more than 2,00 ft (610 meters)above sea level or the surrounding flat lands.
hills Rounded tops that rise above sea level but are lower and less steep than mountains.
plateau Large mostly flat area that rises above its surrounding land. At least one side has a steep slope.
plains Large areas of flat or gently rolling land.
magma Molten rock that pushes up to form volcanoes
earthquakes This is created when blocks of crust, or plates, slide sideways against each other.
volcano This is formed when an ocean crust collides with a continental crust and the ocean crust goes under and melts into magma.
faults Cracks that are formed when two plates push against each other, break and splinter because of the pressure.
Pangaea The huge continent that geographers think the Earth was 200 million years ago.
erosion This happens after weathering, when the small broken down pieces are removed by wind, ice or water.
Earth's three main layers crust, mantle, core
