Weather Cloud & Barometric Pressure
This is Geology Lab report including weather, cloud formation and barometric pressure .
Do you think Tampa will clear within the next 12 hours? Explain your answer.
Yes, Tampa will be clearing in the next 12 hours because the barometric pressure has increased and this clears skies and slows cloud development.
What type of weather is in store for Miami within the next 12 hours? Explain your answer.
Would be the barometric pressure would be rising since cold would have passed through the city. Higher pressure hinders cloud development and clears the skies. Would be the pressure is dropping since the air is rising, this also creates more clouds which create precipitation.
In a hypothetical city such as Gotham City, the temperature is dropping and the skies are clearing. How would the barometer be changing?
The barometric pressure would be rising a cold would have just passed through Gotham. Higher pressure hinders cloud development and clears the skies.
On another day in Gotham City, the temperature is rising, the skies are getting cloudy, and some precipitation begins to fall. How would the barometer be changing?
Pressure reading in barometer will decrease. Barometer is used to measure atmospheric pressure which is nothing but the force exerted due to the weight of an air parcel above any land. In case where this pressure is low, air rises easily into the atmosphere where it cools down and condenses. Condensation produces clouds made up of water, ice and dust particles. After a certain time period these condensed water droplets fall as rainfall. However, if pressure would have been high then the air and water vapor have never reached to a higher altitude where they could condense and form clouds.
Write a hypothesis that describes how you think the rock model with stones will break down.
Weathering is the process by which rocks breakdown or dissolves into smaller stones on the surface of the Earth. The agents of weathering are Water, ice, acids, salts, plants, animals. Once a rock has been broken down, a process called erosion transports the bits of rock away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Weathering is often divided into two
1) Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble.
2) Chemical weathering changes the molecular structure of rocks and soil.
Show how you determined the density for each rock model, and then tell which one is denser.
|Rock Model||Mass (g)||Volume (cm³)||Density (g/cm³)|
Do you think the density of the ice affected the melting rate of the ice, or do you think adding the objects affected the melting rates? Be sure to include data to support your answer.
The density of an object refers to an extensive property, which signifies that it does not rely upon the concentration of the substance. Each and every substance in this world exhibits its characteristic density. Therefore, it would not influence the rate of melting as it does not fluctuate. However, adding the objects could accelerate the procedure as each object exhibits energy in the form of heat, which could provoke the mediating force for the melting process.
Show your data for the melting rate of the conglomerate model and of the plain model. Then, on a separate sheet of paper, graph your data. You may turn in a picture of your curve, or insert a picture of the curve (if graphing using spreadsheet software).
Model 0min 5min 10min 15min 20min 25min 30min 35min 40min
Conglomerate 420g 415g 410g 380g 330g 270g 210g 130g 60g
Plain 230g 225g 210g 200g 185g 170g 155g 130g 115g
According to data, the melting rate for both rock models started very slowly, but as the experiment went on, the plain model continued melting at the same rate. However, the conglomerate model’s melting rate amplified between the 20-25 Min and the 40 Min.
Describe how your graph shows how the ice melted over time in terms of your curve. How did your hypothesis and the true melting curve compare? Would you write a different hypothesis now?

A seismograph station is located 2000 km from an earthquake’s epicenter. Explain the order that the S and P waves will arrive at the station by using the characteristics of the waves.
P waves, also known as primary waves are going to be the first to arrives. These waves have a compressional property, are longitudinal, and can move through both solid rock and liquid. Therefore they are the fastest of the seismic waves. S waves, or Secondary waves, will arrive next. They are transverse waves and have what is called a shearing effect on solid material, which is because they move in a perpendicular fashion. They are much slower than P because the energy is thus less easily transmitted through the medium.
Many geologic features are associated with various plate boundaries. Place an X in the cell for each geologic feature that is associated with the plate boundary labeled at the top of each column.

|Island arc between trench and continent||x|
|Mountains on “coastal side” of trench||x|
|Rift valley extending thousands of miles||x|
|Mountain range with high plateau on one side||x|
|Long linear chain of mountains on seafloor||x|
