In this diagram, the man represents the Sun and the ball represents the Earth. Explain the role of gravity and mass using the man and ball with their representations.
The man is orbiting around the ball.
The ball would not go around in a circle but go off in a straight line even though the man has the ball on a string.
The greatest source of gravity would be the man because he is swinging the ball.
The greatest source of gravity would be the man because he has more mass.

Two air masses collide that have a difference in air pressure - high pressure and low pressure
Two air masses that have only one temperature with one air pressure.
Why does the land and sea breezes change directions of air?
Water temperatures are faster to heat up.
Water temperatures are quicker to heat up and slower to cool off.
Land temperatures change slower than water temperatures.
Land temperatures change quicker than water temperatures.

compaction and cementation
weathering and erosion
How do sedimentary rocks form?
melting and cooling
heat and pressure

The amount of water vapor in the air or atmosphere
Moisture condensed into droplets that falls from the sky
A low level cloud that forms at ground level
Wind, ocean currents, and the water cycle are powered by what?
Solar winds

Convection Currents
The state of Florida has a lot of limestone rock. Limestone is used to make many things. It can be used to make buildings, statues, and monuments. If limestone is used on a building, what effect would acid rain have on the buildings made of limestone over many years?
Oxidizes the limestone turning it into rust
Washes the stone completely white
Dissolves the limestone
Fills the cracks with rain water making them expand and crack.
To determine the age of Earth, geologists use what kind of information?
metamorphic rocks, igneous rocks, sedimentary rocks
Fossils, metamorphic rocks, layering of rocks
Fossils, layering of rocks, radioactive decay
Fossils, igneous rocks, and radioactive decay
A river's velocity or speed slows down as it enters a quiet body of water like an ocean. When it enters this body of water, sediment is deposited to the bottom and forms what land form?
Alluvial fan
Delta
Sand bar
Barrier Island
A farmer in South Georgia planted trees in an open field or flat coastal plain. Why did this farmer expect these trees to help protect his soil from erosion. Select ALL that apply
The leaves from the trees fall making organic matter to make the soil richer in nutrients.
Holds the soils in place to keep it from being washed away
The roots make the soil disappear so it can not be eroded away
Protects the soil from being blown away
A tree was killed by lightning during a storm. What happens to the tree soon after it dies?
A new tree will begin to grow from the dead one.
It begins to petrify.
Other trees will begin to lean into the dead tree place.
It becomes soil
In Maine, it snowed and iced over the pavement in the roads causing the roads to crack when it melted and froze again many consecutive nights. What made the pavement crack?
Snow or frozen water are chemical weathering agents. The snow falls on the roads causing the pavement to crack over time by the frozen acid rain or snow.
Snow or frozen water accumulated on the roads adding weight. As vehicles drove on the roads, the added weight made the roads crack.
Snow or frozen water went into the cracks. It melted and froze causing the cracks to expand and crack.
Snow or frozen water accumulated and packed tightly on the pavement as vehicles drove on them. This weight made the roads cracks.
Weathering by wind and water breaks rocks into smaller pieces. What happens to these smaller pieces that are broken down?
They become bedrock
They become soil.
They stick together making large rock formations.
They are move to another location to form new rock formations.

Bedrock
Parent material
Subsoil
Topsoil
What is humus?
Organic matter
Organic layer
Slightly weathered rock with minerals
A layer of soil with mostly minerals, nutrients, and iron ore
Why are more volcanoes likely to form around the "Ring o Fire?"
Volcanoes form in the middle of tectonic plates.
Volcanoes are more likely to form where tectonic plates meet.
Volcanoes form where there are the most mountain ranges near salt water.
Volcanoes form where there are more warm weather islands.
Most rock on Earth is hot enough to flow in patterns. The hot rock or magma in the mantle rises to the top of the mantle, cools, then sinks, reheats, and rises again. What are these patterns called?
