This document lists the names and locations of 12 individuals from various states and countries including Iowa, Washington, New Jersey, Maryland, Oregon, Hawaii, Georgia, Atlanta, Michigan, and Pennsylvania.
This document discusses the concept of significant figures and how to determine the number of significant figures in measurements and calculations. It defines significant figures as the "important digits" that indicate the precision of a measurement. Rules are provided for determining significant figures depending on leading or trailing zeros and whether the number is read from left to right or right to left. Examples demonstrate applying these rules and how to round final answers in calculations like addition, subtraction, multiplication and division based on the least precise measurement used. The key takeaway is that significant figures convey precision and final answers should not be more precise than the least precise input.
This document discusses hypothesis testing. It explains that hypothesis testing is used to determine if data is statistically significant enough to reject or fail to reject the null hypothesis. The key aspects covered are:
- Identifying when hypothesis testing is appropriate
- Distinguishing between the null and alternate hypotheses
- Determining whether to reject or fail to reject the null hypothesis based on comparing a test statistic to a critical value from a distribution table
This document discusses how scientists measure the hydrologic cycle. It describes traditional methods like stream gaging stations, groundwater wells, and SNOTEL stations to monitor streams, groundwater levels, and snowpack. It also discusses newer geodetic methods like GPS and GRACE satellites that can measure subtle changes in gravity or ground movement related to water storage and flow. These comprehensive measurements across different reservoirs help scientists better understand the complex global hydrologic cycle.
The document discusses how the coastline of North America during the Cretaceous Period 80 million years ago, with a Western Interior Seaway dividing the continent, still influences patterns today. It notes that the fertile soil deposited along this ancient coastline attracted slave plantations, and after emancipation the populations remained high in African Americans. As a result, modern voting patterns follow the same curve as the long-gone Cretaceous coastline, with counties with larger African American populations voting predominantly Democrat.
This PowerPoint document provides instructions for an activity to analyze climate and biomes using data on cities from around the world. Students will sort city climate information cards into biome categories, plot locations on a map, and fill out a worksheet characterizing climate and biome for each city. The PowerPoint includes over 50 slides providing detailed climate and location data on cities to support categorizing into biomes.
This document provides instructions for tracking weather systems using maps. Students are asked to print maps showing the location of low pressure centers over time. By examining the date and time stamps, students track one low pressure system as it moves across the United States over several days, recording its location on blank maps. They then connect the locations with a line to show the storm's path. Students also have the option to track additional storms, measure distances traveled between maps to calculate speed, or use software to analyze and animate the map images.
This document provides an overview of traditional and geodetic methods for measuring water resources. It discusses the hydrological cycle and key reservoirs and fluxes. Traditional measurements like gauging stations and SNOTEL stations that measure snowpack are introduced. Geodetic methods using GPS and gravity satellites are presented as newer techniques to measure vertical land motion, snow depth, soil moisture, and groundwater levels. Declining trends in snowpack and streamflow in Montana watersheds are highlighted as impacts of climate change on water resources. Stakeholders in water resources like local residents, industry, and government are identified.
This document defines and compares the three main measures of central tendency: mean, median, and mode. It explains that the mean is calculated by adding all values and dividing by the total number of values, the median is the middle value when the values are arranged in order, and the mode is the most frequently occurring value. The document also notes that outliers can affect the mean more than the median or mode. An example calculation is provided to demonstrate how an outlier impacts each measure. The key takeaway is that the mean, median and mode are important for summarizing large datasets with a single representative value.

Soils are essential to supporting life and human civilization. As populations grow, pressures on soils increase and maintaining soil health is important. Throughout history, human activities like deforestation, overgrazing, and poor irrigation have led to soil degradation problems like erosion, desertification, and salinization. This has negatively impacted societies by reducing agricultural productivity and sometimes causing civilizations to fail. However, more recent initiatives show people rediscovering the importance of soils and taking steps to promote sustainable land use and soil conservation.
The document discusses soil classification systems and soil surveys. It explains that soil taxonomy is a hierarchical system used to classify soils based on observable properties like color, structure, and chemistry. Soils are grouped into increasingly broader categories from the most specific level of series up to the broadest level of order. Soil surveys involve soil scientists mapping and describing soils in a given area in order to group soils with similar properties. The classifications aim to convey information about soil formation and management needs.
The document discusses nutrient management and soil fertility. It outlines key nutrients needed by plants and their analogous benefits for human health, including nitrogen for growth, potassium for water uptake and disease resistance, and calcium for growth and strong bones. It also addresses how soil pH impacts nutrient availability and describes common nutrient deficiencies like zinc deficiency that causes stunted growth and yellowing.
This document discusses several issues that can negatively impact soil quality including disturbed and degraded soil, desertification, deforestation, salinization, run-off, mineral extraction, and wind erosion. These processes can damage soil structure and reduce fertility.
The document discusses the major biomes of the world and the soils typically found within each one. It describes the key biomes as tropical rainforests, temperate forests, boreal forests, grasslands, tundra, deserts, shrublands, and wetlands. Each biome is defined by its climate, vegetation, and characteristic soil orders that form as a result of the particular environmental conditions within that biome.
This document discusses the physical properties and formation of soil. It describes how soil characteristics like color, texture, structure, and horizons/profiles influence water movement, storage, erosion, and plant growth. Soil formation is influenced by climate, organisms, topography, parent material, and time in a process known as CLORPT. The physical properties of soil determine how quickly water can infiltrate and percolate through different soil types.
This document discusses various natural and human-caused processes that can degrade soils, as well as best management practices to mitigate soil degradation. It covers topics like erosion from water and wind, desertification, acidification, salinization, effects of deforestation, urbanization, construction projects, land application of manures and wastes, and mining reclamation. Sustainable land management and soil conservation techniques aim to renew resources rather than deplete them over time through practices like maintaining vegetative cover, controlling grazing intensity, and properly applying nutrients from wastes.
This chapter discusses the living components of soil, including bacteria, fungi, protists, and fauna. Bacteria and fungi play important roles in nutrient cycling and forming soil structure. Fungi exist as filaments called hyphae that can form partnerships with plant roots. Protists include amoebas, ciliates, and flagellates that consume bacteria and debris. Larger soil fauna include earthworms, nematodes, springtails, and arthropods that further break down organic matter and improve soil structure through bioturbation. The variety of organisms in soil work together to create a living system that supports plant growth.
This document discusses the 2012-2017 California drought and its impacts. It provides historical context on droughts in California and examines precipitation data. Specific topics covered include:
1. The spatial extent and timing of the 2012-2017 drought across California and how it compares to historical droughts.
2. How precipitation was measured using tools like snow pillows and GPS reflection to track snow levels.
3. The societal impacts of the drought, including mandatory water rationing and transformations to California's landscape and economy.
This document discusses using GPS vertical positioning to monitor groundwater storage changes. It begins by explaining that groundwater mining is a global problem, and that extracting groundwater causes the land surface to rise as the total water storage decreases. It then discusses how GPS networks can detect these vertical position changes at the sub-centimeter level on a daily basis, allowing monitoring of seasonal water changes. Finally, it notes that long-term groundwater pumping can lead to both reversible and irreversible subsidence exceeding several meters, and provides examples from California's Central Valley.
This document discusses methods for characterizing groundwater storage, including traditional well measurements and satellite-based GRACE observations. It defines terrestrial water storage as all water on the land surface, and explains that groundwater often dominates variations in storage. Wells measure groundwater levels, with changes indicating replenishment or depletion over time. GRACE satellites detect changes in mass distribution and associated gravity field variations to infer changes in total water storage, including groundwater, at coarse spatial scales. The document provides examples of using both approaches to monitor groundwater in key aquifers.
The document provides an introduction to GPS/GNSS basics, including:
- GPS uses 24-32 satellites in medium Earth orbit that transmit positioning and timing data. Receivers need signals from 4 satellites to calculate a 3D location.
- Ground control stations monitor the satellites and send updates to synchronize their atomic clocks and orbital data.
- GPS determines location by calculating distances to satellites using signal transmission times and triangulating the receiver's position.
- Precise GPS uses permanent stations with stable monuments to collect data over many years, achieving sub-centimeter positioning and millimeter-per-year velocity estimates.
The document discusses the normal distribution, which is a specific type of probability distribution where the mean, median, and mode are centered around the middle. It depends on the mean and standard deviation. The document describes the key elements needed to construct a normal distribution like the mean and standard deviation. It also provides an example of calculating the percentage of yearly pizza sales that would be less than $90,000 given the normal distribution of annual sales has a mean of $120,000 and standard deviation of $30,000. Approximately 16% of yearly sales would be less than $90,000.
This document introduces linear regression as a method to model the relationship between two variables. It explains that linear regression can be used to predict future values of a dependent variable from a independent variable. The document demonstrates linear regression by plotting ice cream sales against temperature and fitting a linear model to the data, showing that sales increase with rising temperatures. It defines R2 as a measure of how well the linear model fits the data points, with higher R2 values indicating better fit.
This document discusses the correlation coefficient and how it can be used to quantify the relationship between two datasets. It explains that the correlation coefficient ranges from -1 to 1, with values closer to those extremes indicating a stronger linear relationship. While correlation does not prove causation, it is useful for determining how closely two variables vary together when their relationship is linear. The document also notes that correlation may not capture non-linear relationships and provides examples of interpreting correlation coefficients.
This document provides an introduction to flooding and floodplains. It defines flooding and different types of floods. It discusses the natural functions of floodplains and how human development can impact flooding. The document outlines several strategies for floodplain management, including modifying human and flood impacts, and preserving natural resources. It also introduces key hydrologic concepts like return periods and how the 100-year flood is used in flood hazard assessment and management.
