activity‚ Yellowstone National Park was established in 1872 and covers the largest area‚ encompasses nearly 3‚500 square miles. The park has Old faithful geyser‚ Lake Yellowstone which is in the caldera of a dormant volcano‚ and the park also has bubbling mud pots‚ hot springs and hot colorful pools. More than half of the world’s geysers are located in Yellowstone. There are 10‚000 thermal features in the park and only 3% are geysers. The most famous one is Old Faithful‚ named because of its reliability

The motivation behind the Apollo missions was for the USA to be the first people to land on the moon. Russia had beaten us to outer-space and had put a satellite out in space before us. We wanted to be the first ones to reach the moon and to retrieve new information and data. Scientists needed the help of NASA to answer some important questions and hypotheses. Scientists wanted to know the origin of the moon‚ the temperature history of the moon‚ the cause of mascons‚ and the origin of tektites. Scientists

into the city of Los Angeles‚ California. The evaporating of harmful gases‚ earthquakes‚ and some evidences from the manhole are the manifestations showed that an underground volcano was forming under the city. This means that there was already lava under the city and the ground cannot take the pressure anymore so it formed a volcano. The physical changes in the movie are the breaking of glasses from buildings‚ breaking of buildings‚ cracking of the ground‚ boiling of water from the pond‚

sedimentary rocks and metamorphic rocks. I. The first type is igneous rocks (from the Greek word for fire) which are formed from molten rock (magma) and lava. A. Formation 1.coming up of magma through cracks 2. forming a layer on surface or filling other cracks 3. cooling forming a very hard igneous rock 4. magma on the surface of the earth‚ lava _ basalt B. Importance 1. geologically important - showing characteristics of a specific tectonic environment 2. allowing tectonic reconstitutions

pockets. As these pockets of magma cool slowly underground‚ the magma becomes igneous rocks. Igneous rocks also form when volcanoes erupt‚ causing the magma to rise above the earths surface‚ above the earths surface magma is called lava. The rocks are formed as the lava cools. Sedimentary rocks are formed at the surface of the Earth‚ either in water or on land. They are layers of fragments of rocks‚ minerals‚ or animal or plant material. Most sedimentary rocks become cemented together by minerals

There are two types of volcanic flows pyroclastic and mud flows. Pyroclastic volcanoes occur when the amount of magma in the chamber collects and the pressure increases causing the volcano to erupt. Mud flows are kind of like pyroclastic accept the lava in the chamber doesn’t collect and cause an eruption it just flows out the top of the volcano. Mount Etna is located on the island of silicon‚

from the investigation. Guiding Question How does the temperature of a solution affect a reaction rate? Pre-planning This lesson will have students investigating the effect of temperature on a simple chemical reaction‚ effervescent tablets bubbling in water. (Be sure to use uncoated tablets.) The students will design an experiment to test their hypotheses and gather data to create and support their conclusions. We will provide students with warm water‚ cold water‚ and room-temperature tap water

Most people are unfamiliar with the positives of Volcanoes. Volcanoes do cause destruction to people’s houses (and other things) but‚ the ash‚ rocks‚ lava‚ etc. improves the landscapes and the environment. It also makes great soil for farming‚ crops‚ and tilling. They are improving the natural scenery of the land and creating food and work for the people. The volcanoes affect the land in a good way because it is helping to improve our environment/earth. Nowadays‚ people don’t see difference
