events in each era. Did more Earth-shaping events occur early in Earth’s history or later on? Explain why. Based on my geologic time scale‚ there are three events in Precambrian Time‚ two events in Paleozoic Era‚ four events in Mesozoic Era and one event in Cenozoic Era. These events mostly occurred later on in Earth’s history. Mesozoic Era has the most events which are four out of ten events on the list‚ mean that Earth-shaping events happened more recently. Earth-shaping events occur later on

Dynamic Earth Has the Earth been static since the beginning of time? Well‚ Earth hasn’t been moving vigorously but it is changing at a steady rate. New geological features‚ rock formations‚ and locations of plates all rise and demolish some in a lifetime and others over a span of millions of years. Earth is dynamic; it constantly progresses and doesn’t rest. Through the churns and molds‚ the twists and turns‚ Earth is active because of plate tectonics and the rock cycle. The ideas

Earth Quake Cause and Effect Essay BY: Jean Rosario Teacher: Jessica Heyett An earthquake‚ one of the most destructive natural disaster‚ consists of rapid vibrations of rock near the surface of the earth. It is the most terrifying of all natural disasters and has brought fear since ancient times because of its sudden unpredictable occurrence and enormous capacity of destruction. Earthquakes can effect earth‚ people‚ and property in everyday lives. Earthquakes change the earth’s formations in different

AGE OF THE EARTH Scientists have settled on the age of the earth of about 4.6 billion years as a result of research started almost 50 years ago. This conclusion was based upon carefully designed and conducted experiments that compared the ratios in rock samples of parent elements to daughter elements ( some of which would have been from radioactive decay of the parent‚ some of which may have been present in the sample at the time of formation). Since radioactive decay is known to occur at a constant

ENGLISH CLASS 2013 PLANET EARTH OUR PLANET TEACHER ERICKA SANTIESTEBAN COLEGIO LA ROCA Earth is the third planet from the Sun‚ and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System’s four terrestrial planets. It is sometimes referred to as the world‚ the Blue Planet‚ or by its Latin name‚ Terra. Earth formed approximately 4.54 billion years ago‚ and life appeared on its surface within one billion years. Earth’s biosphere then

EARTH SURFACE REALMS 2And3 We can look at Earth’s surficial "layers" as being comprised of several major realms or "geospheres": the atmosphere‚ lithosphere‚ hydrosphere‚ biosphere and pedosphere. The reference to "sphere" applies because Earth is spherical‚ and hence layers around it form somewhat spherical shells at the outermost edges of the solid planet. The atmosphere‚ biosphere and lithosphere more completely encircle Earth‚ while the hydrosphere and pedosphere tend to be more discontinuous

Life on Earth. 1. Analysis of the oldest sedimentary rocks provides evidence for the origin of life. * Identify the relationship between the conditions on early Earth and the origin of organic molecules. * Scientists estimate that the universe is 10-20 billion years old and arose as a big bang‚ which is still expanding the universe. * The early Earth was very different from the Earth today and no oxygen was present. This means that there was no ozone layer exposing the Earth’s surface
