Lesson 1
The place where organisms live and obtain all the things it needs to survive.
What is a habitat?
A river and all the streams and smaller rivers that flow together
What makes up a river system?
A characteristic of a material that contains connected air spaces, or pores, that water can seep through easily.
What is permeable?
Movement of energy through a body of water.
What are waves?
A large stream of moving water that flows through the oceans.
What is a current?
evaporation,transpiration, condensation, precipitation, run off
What is the water cycle?
A small and shallow body of water with lots of plants, bacteria, and different types of organisms.
What is a pond?
Sodium chloride that dissolves in water and separate into sodium AND chloride particles.
What are ions?
The horizontal distance between crest.
What is wavelength?
The Gulf Stream
What is the largest and most powerful surface current in the North Atlantic Ocean?
After water molecules evaporates, warm air carries the water molecule upward. All the water molecule condense in the air.
How do clouds form?
Drainage basins
What are watersheds?
They drill a well below the water table.
How can people obtain groundwater from an aquifer?
Wind blows across the water's surface transmit their energy to the water.
How do waves form?
By moving cold and warm water around the globe.
How do currents effect climate change?
Precipitation falls to the ground and some of the run off get soaked into the land
How does water get into the ground?
1.A river bends and loops
2.a new channel forms cutting off a loop
3.the cut of becomes it's own lake
How do oxbow lakes form?
The surface zone
What zone is the warmest?
Wave height increase and wavelengths decreases.
What happens to waves near the shore?
The Earth rotates and the paths of the winds and currents curves.
Why do the currents move in these circular patterns?
There's salt in the ocean and salt makes it harder for water molecules to bond to the ice structure
Why doesn't the ocean freeze?
Algae covers the lake so sunlight cannot reach the bottom so plants and animals die. The bodies and dead plants make the lake shallower and plants grow in the mud. Eventually, the area fills with plants and a meadow replaces the former lake.
A ship's sonar system send out pulses of sound that bounce off the ocean floor. The equipment then measures how quickly the sound waves return to the ship.
How does sonar work?
As a sandbar grows it can trap the water flowing along the shore. In some places, water breaks through the sandbar and begins to flow back down the sloping ocean bottom.
How do rip currents form?
1) an unusual patter of winds forms over the western Pacific
2) this causes a vast sheet of warm water to move east toward the South American coast
3) this warm water prevents the cold deep water from moving to the surface
How does El Nino form?
