Weather – condition of the atmosphere at a particular time and place. Atmosphere – mixture of the gases that surrounds the Earth. Altitude – height of an object above the Earth. Troposphere – layer with 90% of the atmosphere’s total mass; layer where we live; (gets colder as you go higher) Stratosphere – layer with the ozone layer; (gets warmer as you go higher) Mesosphere – coldest layer of the atmosphere; (gets colder as you go higher) Thermosphere – greatest heat, but not hot due to distance between air particles

( gets warmer as you go higher) 8. Conduction – transfer of thermal energy by direct contact. 9. Greenhouse effect – Earth is getting warmer due to pollution and loss of ozone 10. Wind – moving air 11. Coriolis effect – Earth’s rotation causes objects (wind) to follow a curved path 12. Trade wind – winds that blow from 30 degrees lattitude to the equator 13. Westerlies – winds that blow from 30 to 60 degrees lattitude 14. Polar easterlies – winds that extend from 60 degrees lattitude

Water on Earth There are two types of water: Fresh water & Salt water Fresh water is water that is not salty Most rivers and lakes are fresh water Salt water is water that contains dissolved salts and other minerals Water in the ocean is salt water Humans and most land animals can not survive by drinking salt water

Earth’s Water Most of water on Earth is in the ocean 97% is salt water Only 3% is fresh water

Water Cycle http://www.sweetwater.org/education/watercycle.swf

Water Flows and Collects Water collects in rivers and streams River Systems Tributary- a stream that flows into a lake or into a larger stream

Water Flows and Collects River systems are divided into watersheds Watershed (drainage basin) Land that is drained by a water system largest watershed is the Mississippi River watershed

Stages of a River Youthful Rivers Mature Rivers Old Rivers Rejuvenated Rivers

Stream & River Deposits Deposition is the process where material is dropped or laid down Rock and soil deposited by streams are called sediment

Delta River deposits its load in a fan-shaped pattern A river empties into a large body of water Exp: Mississippi River flows into the Gulf of Mexico

Deposition on Land Alluvial fans Floodplains Fan-shaped deposits that form on dry land Floodplains Area along a river that forms from sediments deposited when a river overflows Rich farming areas

Prevent Flooding Dam Levee Barrier to redirect the flow of water Buildup to control flooding

Conserve Water Only 3% of Earth’s water is drinkable Most of the fresh water is frozen in icecaps and glaciers How do we misuse our water? How can we conserve water?

Pollution 2 types of Pollution: Point-Source Pollution Pollution that comes from a specific site Can mostly be controlled Exp: a leak from a sewer pipe Nonpoint-source Pollution Pollution that comes from many sources Difficult to control Exp: street gutters, fertilizers and soil

Water has to be treated… http://www.classzone.com/books/ml_sci_earth/page_build.cfm?id=resour_ch1&u=3#

Earth’s Ocean What is the largest ocean? Pacific Ocean What is the smallest ocean? Artic Ocean Ocean water is salty. Ocean water is not safe to drink.

Short Answers to Review Questions Coastal water in hotter, drier climate typically has higher salinity because less freshwater runs into the ocean in drier areas. Heat increases the evaporation rate.

Technology used to study the ocean floor includes sonar and research vessels such as Alvin and Deep Flight. Sonar, research vessels and satellites are used to study the ocean floor.

The two major regions of the ocean floor are the continental margin and the deep-ocean basin. They are all sections of the continental margin.

Living resources- fish and seaweed Nonliving resources- oil and minerals

Short Answers to Study Guide Nonpoint-source pollution comes from many sources (run-off, gutters, fertilizers, etc.) Point-source pollution comes from

Watersheds Watersheds are separated from each other by an area of higher ground called a divide Exp: Continental Divide

Stream Erosion What factors cause a stream to flow faster? Gradient- change in elevation Discharge- amount of water carried Load- materials carried by a stream
