Oceans
What percentage of the Earth is covered by oceans?
71%
What is a ocean tide?
The rise and fall of the level of the ocean surface.
What is a renewable resource?
A resource that can be replenished/replaced over time.
What are three types of rocks?
Igneous, Metamorphic, Sedimentary
Which sphere are the oceans and seas a part of?
The hydropshere
Name 2 uses and 2 abuses of the Oceans
Uses- transportation, employment, fishing, entertainment, weather/climate, energy, air, shipping
Abuses - overfishing, pollution, oil spills, ocean acidification
What cause the oceans tides?
The gravitational force/attractions between the Earth, Sun, and the Moon.
How is a non renewable resource different from a renewable resource?
A renewable resource can be replenished naturally within a relatively short period, while a non-renewable resource cannot be replenished at a rate that can keep up with consumption.
Which rocks are made from heat and pressure?
Metamorphic Rocks
What are the four main spheres we have studied?
Atmosphere, Lithosphere, Biosphere, and Hydrosphere
What is salinity?
Salinity is the measurement of dissolved salts in water.
What is upwelling?
Upwelling is when deep, cold NUTRIENT -rich waters rise to the surface in some parts of the ocean.
Solar energy - Energy from sunlight that can be captured using solar panels
Is this RENEWABLE or NON-RENEWABLE?
Renewable
Which rocks are made from weathering, compaction, and cementation?
Sedimentary Rocks
Which two spheres does the moon's gravity pull on?
Hydrosphere and Lithosphere
Which is denser, salt water or fresh water?
Salt Water
What are five causes of the movement of major ocean currents?
wind, tides, density of water, rotation of Earth, and gravity
Petroleum (oil) - A fossil fuel used for gasoline, plastics, and many other products
Is this RENEWABLE OR NON-RENEWABLE
Non-Renewable
What type of rock?
During a field trip to a local park, your class found this rock sample:
**A black, glassy rock with small bubbles throughout. It has sharp edges and appears to have cooled quickly from a molten state.
Igneous Rock
WHICH SPHERE
Sarah and her family spent the day at Pine Lake Park. They had a wonderful time exploring different parts of the park. During their visit, Sarah noticed:
Biosphere
Why is salinity, pH levels, and nutrients so important to the ocean?
All three must be balanced for the oceans and ocean life to thrive and survive.
How do ocean currents affect Earth's weather patterns?
Currents, like the Gulf Stream, carry warm water that can warm nearby areas. As well as carrying moisture around the globe.
Imagine you're visiting a small town called Greenville. During your visit, you notice the following resources being used:
1. Renewable
2. Non-Renewable
3. Renewable
4. Renewable
What law or principle states that stacks of rock layers that have not been severely disturbed, have the oldest layers at the bottom and the youngest layer at the top?
law/principle of superposition
Which TWO Spheres?

Atmosphere and Lithosphere
