following table to compare extrusive and intrusive rocks. Describe and compare each type in at least 150 words. Extrusive Rock Intrusive Rock Extrusive rocks are also called volcanic rocks and extrusive rocks are formed on the earth’s surface. Extrusive rocks also form from magma‚ but a form of lava. Magma flows onto the earth’s surface by an eruption by a volcano. When the magma hits the earth’s surface‚ the magma turns into lava. Extrusive rocks are formed by lava‚ and the lava will harden quickly

A rock is another rocks raw materials‚ meaning rocks that dinosaurs used to step on‚ are what make up the rock we use to skip on the lake. The quick and simple way to answer how that could be true is‚ the rock cycle‚ but the rock cycle is actually very complex. It involves the formation and deterioration of rocks also it is connected with many of the other cycles in the earth. The rock cycle shows “one rock is the raw material for another” due to rocks going through three different phases: igneous

What Makes Rocks and Gems Different? By: Morgan Bellile Have you ever found a beautiful gem? Have you ever wondered what is in rocks? Did you know that red diamond is one of the most rare types of gems? Rocks and gems both have something in common‚ but have you ever wondered what makes rocks and gems different? Gems Gems are also known as precious stone‚ jewels‚ or just stone. What is a gemstone? A gemstone is a piece of mineral crystal‚ when the gem is cut and polished‚ it is normally used for

Explain the operation of the rock cycle with reference to the geology in Hong Kong. To what extent are the rock types responsible for the deep weathering profile in the territory? Hong Kong is dominated by igneous rocks which granite takes up the largest proportion of 85% of the total land area. The remaining area is underlain by sedimentary rocks superficial deposits mainly in the North West area. Other than the above rock types‚ there still a kind of rock which covers only a small area of Hong

Sedimentary rocks from the Barberton greenstone belt‚ South Africa Abstract The Barberton greenstone belt in South Africa represents one of the best preserved successions of Archaean rocks. The rock sequences have experienced low grade metamorphism‚ which makes them ideal to study because the effects of alteration and secondary minerals are relatively small. The sedimentary rocks of the Fig Tree Group obtained through the drilling project “Peering into the cradle of life” are analysed for their

Everyone knows the RPS game. The RPS game is the Rock Paper Scissors game. All players display one of three symbols‚ a rock by making a fist‚ a piece of paper with a flattened palm‚ or a pair of scissors with fingers extended. If a rock and scissors are formed‚ the rock wins because a rock can crash scissors. If paper and a rock are formed‚ the paper wins because a sheet of paper can cover a rock. If scissors and paper are formed‚ the scissors win because scissors can cut paper. If you both pick

Earth’s volume. The mantle consists mostly of molten rock called magma with a solid upper layer. A few gemstones form in the mantle‚ but all gems are mined in the crust. The crust is made up of three kinds of rock‚ known in geology as igneous‚ metamorphic and sedimentary rock. These technical terms refer to the way in which the rock is formed. Some gemstones are associated with one kind of rock in particular; others with several types. The igneous process involves the solidification of magma. Magma
