If you were an alien visiting Earth for the first time, you might remark on the diverse and incredible landscapes and patterns around majestic mountains, green forests, rolling grasslands, and turquoise oceans. You also might recognize geometries of civilization and changing weather patterns. All this can be explored from space. In this activity you will explore our planet using Google Earth and locate natural and man-made patterns and landscapes on Earth’s surface that inspire you.
Maps are two-dimensional ways of representing information about the natural and built world from a "top-down" perspective. You are probably familiar with road maps that show where roads go and which roads intersect with others and where. You also may have seen weather maps, which show weather patterns across a specific geographic area, or political maps, which show where borders are for countries and areas within those countries.
Geoscientists use special boats to conduct research at sea. One of these boats is named the JOIDES Resolution (JR). Unlike most oceangoing vessels, the JR has a flat bottom, a 6.4-meter hole in the middle, 12 laboratories, and a derrick towering 67 meters above the waterline! Why? So scientists can sail nearly anywhere in the world to drill for samples of rocks and sediment from below the seafloor. What for? In hopes of discovering clues about Earth's history and structure, life in the deep biosphere, past climate change, earthquakes and natural resources.
This investigation will help you to learn that different geologic materials have different characteristics.
Learn the characteristics of difference kinds of minerals in this hands on investigative activity.
A normal fault occurs when rocks break and move because they are being pulled apart. As the area is stretched, the rocks move along the fault. Each movement causes an earthquake. This model demonstrates how a block of rock is extended by a normal fault.
Groundwater is contained in the zone of saturation below the land surface. The top of this zone is known as the water table. People can tap into this source of water by drilling wells. The depth of the well and level of the water table greatly influences the wells productivity. In this activity you will demonstrate the relationship of groundwater to wells.
The five national marine sanctuaries along the West Coast monitor the health of the rocky intertidal ecosystem. One way of doing this is to collect data on the relative abundance of the organisms living in that ecosystem. Since this is such a big task, the national marine sanctuaries are training students in how to follow standardized protocols to help with the monitoring. The information collected is added to an online database that the sanctuaries use to collect baseline data and track long-term changes in the environment. This activity will allow you to learn the sampling techniques used in the field by these citizen scientists who participate in LiMPETS.
Learn about fossil preservation, paleontology, and stratigraphy in this detailed activity from the USGS.
Natural gas, which is mostly methane, is an energy resource used for generating electricity and heating, powering transportation, and manufacturing products. Right now, one-quarter of the world’s energy comes from natural gas. In this investigation, you will make a simple model of how gases can form from decaying material. You will also explore the effects of temperature on gas formation.
