The Awesome Earth Science Midterm Review Quiz Thing

The relationship between density and pressure is direct. This means that as the density of a substance increases, the pressure it exerts also increases. Similarly, as the density decreases, the pressure decreases as well. This can be observed in various scenarios, such as when a gas is compressed, its density increases, leading to an increase in pressure. Conversely, when a gas expands, its density decreases, resulting in a decrease in pressure.

The relationship between density and temperature is indirect. This means that as temperature increases, the density of a substance decreases, and as temperature decreases, the density increases. This can be explained by the fact that as temperature rises, the particles in a substance gain more energy and move faster, causing them to spread out and occupy more space, resulting in a decrease in density. Conversely, as temperature decreases, the particles lose energy and move slower, causing them to come closer together and occupy less space, resulting in an increase in density.

I wonder who actually answers as "married"....

Physical/Mechanical Weathering
Abrasion = The rubbing together of particles
Root/plant Action = roots grow out and break apart rock
Frost Action = repeated freezing -expanding- and melting -contracting- breaks rock/thermal action = repeated when hot -expands- and cool -contracts- breaks down rock
Pressure Unloading/Exfoliation = weight causes a crack in a rock as overlying rock is removed, rocks expand and peel away
Biological Activity = animals and insects cause exposure of rock and abrasion
Chemical Weathering
Hyrolasis = rust, water dissolves some minerals in rocks
Oxidation = rust, minerals combine with oxygen
Carbonation = CO2 + rain H2O = weak carbonic acid eats away at rock, poor rock, makes caves
Biological Decay = decomposing plants, animals and insects release acids into the ground

Highest point doesn't always mean highest counter line, it means....well....highest point

Even though Earth IS NOT a perfect sphere and IS a "oblate spheroid", visually from above its "oblate spheroid"-ness is so tiny that it looks like....well, a basketball.

This one is self-explanatory, I feel, obviously choice E

Gravity is the correct answer because it is not an erosional agent itself, but it influences the movement of other erosional agents such as running water, wind, and glaciers. Gravity causes rocks to fall and be transported downhill, resulting in their jagged or uneven appearance. It also plays a role in the deposition of sediment, causing it to be deposited in an unsorted manner.

Polaris is also known as the North Star and is located very close to the North Celestial Pole. This means that it appears directly above the Earth's North Pole. Therefore, if an observer on a ship measures the altitude of Polaris at 60 degrees, it means that the ship is located at 60 degrees north latitude. The longitude is not provided in the question, so it can be assumed to be 0 degrees longitude.

Glaciers are the correct answer because they have the ability to erode rocks and create grooves, striations, or scratches on their surface. This is due to the movement of the glacier and the debris it carries, which acts like sandpaper on the rocks. The parallel pattern of these features is a result of the consistent movement of the glacier. Additionally, glaciers deposit unsorted material when they melt, as they release the debris they have been carrying, creating distinct landforms.

The color of a rock or mineral does not have an effect on the rate of weathering. Weathering is the process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological means. Factors such as climate, exposure to the elements, strength of the minerals, and amount of surface area exposed all play a role in the rate of weathering. However, the color of the rock or mineral does not impact this process.

As a person travels northward from the Equator, the altitude of Polaris will appear to increase. This is because Polaris, also known as the North Star, is located very close to the celestial North Pole. As one moves closer to the North Pole, the angle between the horizon and Polaris increases, causing it to appear higher in the sky. Conversely, as one travels southward from the Equator, the altitude of Polaris would appear to decrease.

Running water is the correct answer because it has the ability to polish rocks as it flows over them. The force of the water, combined with the sediment it carries, can wear away rough edges and create a smooth and polished surface on the rocks. Additionally, running water has the ability to sort and round the deposited sediments, further contributing to the polished appearance of the rocks.

Every 15 degrees is an hour, no?

I believe that if you know a formula for Earth Science, there really isn't any need in having a practice problem........all you do is plug in the numbers

All pure elements, regardless of size, share the same density properities

Check thy Earth Science Tables and whatnot, page two if I remember correctly

A ridge is associated with a divergent plate boundary that will move tectonic plates apart. Along the E. Pacific Ridge there most likely will be volcanic activity which produces new oceanic crust, and the further from the ridge one travels the older the age of the bedrock (oceanic crust). With this being said the point furthest from the ridge will be the oldest in age. Since #1 is the furthest away it is the oldest in age.

The density of an object is calculated by dividing its mass by its volume. In this question, the mass of the bar is given as 90 g, but the volume is not provided. However, we are given the dimensions of the bar, which are 5 cm x 2 cm x 3 cm. To find the volume of the bar, we multiply these dimensions together: 5 cm x 2 cm x 3 cm = 30 cm^3. Therefore, the density of the bar is calculated as 90 g / 30 cm^3 = 3.0 g/cm^3.

Valley X has the most severe erosion due to the fault located in the area. A fault will cause the bedrock on both sides to move opposite to one another causing an earthquake. The earthquake could also cause a weakening of the bedrock in the area due to the shaking of the ground.

Wind is the correct answer because it is an erosional agent that can cause sand particles to become frosted or scratched, with rounded edges. Wind can pick up and transport sand particles, causing them to collide with each other and with other surfaces, resulting in abrasion and erosion. As the wind carries the sand, it can also sort the particles by size, with larger particles being deposited closer to the source and smaller particles being carried further away.

The missing term that completes the analogy is "Subsoil". The analogy compares "Topsoil" to "dark, organic nutrients", implying that topsoil is rich in organic matter. Similarly, the missing term is compared to "Leached Minerals via H2O", suggesting that subsoil is the layer of soil where minerals are leached or washed down through the soil profile by water. Therefore, "Subsoil" is the correct answer.

To find the answer go to p. 11 of the Earth Science Reference Tables. Locate the P-wave line. Then locate 6500km on the x-axis of the P and S-wave chart. Follow the 6500 line up to the P line, when it intersects follow the line to the left and locate travel time.

Well that was not grammatically correct, but no, it is not the fallen king of Gondor, sorry

Residual Soil = has never been moved by a weathering agent, therefore composition is the same as the bedrock
Transported soil = has been moved by an erosional agent, therefore composition is different from the bedrock

You must go to p.5 of the reference tables to answer this question. Locate point A on p.5 of the tables. One should find that point A is found between the Pacific Plate and the Nazca Plate.

Yeahhhh I really like Narnia incase you missed that memo

Ohh wait, this isn't Chemistry, so significant figures don't count >.

The correct answer is "Percent Error = |accepted value - observed value|/accepted value * 100." This formula is used to calculate the percent error, which measures the accuracy of an experimental result by comparing it to the accepted value. By taking the absolute difference between the accepted value and the observed value, dividing it by the accepted value, and then multiplying by 100, we can express the error as a percentage.

If you really put Narnia my dear, I am laughing like you have NO CLUE....
