thick‚ the sediment at its thickest was only 1000ft. ⦁ Ewing reached the ridge not only did the sediment get even thinner but dredges also began collecting volcanic rock. Later seismic data would eventually show that the sea floor was composed of basalt‚ an extrusive igneous rock‚ and was only a few miles thick. ⦁ Hess would leave the sounding equipment on that would take measurements of the sea floor. It was at this time that Dr. Hess discovered features on the floor of the ocean that appeared

The Dynamic Crust‚ Earthquakes and the Earth’s Interior Why is the Earth’s crust described as being dynamic? Crust- solid rock outer zone of Earth The crust is part of the lithosphere. The Earth’s crust is dynamic which means constantly changing.

consolidation (Alexander‚ 2013). Parent material is the dominant factor over texture (Alexander‚ 2013). The parent material provides the basic mineralogy for the soil‚ thus soils formed from granites tend to be sandy and infertile‚ while those formed from basalts will have a higher clay content and have an increased fertility (Alexander‚ 2013). Within each region‚ such as the tropics‚ the parent material varies significantly throughout and is not one consistent type. Therefore the variety of parent material
