Science 10 q1

• Mountain ranges are found only in places where volcanoes are situated
• The Earth has four layers consisting of different materials, namely, crust, mantle, inner, and outer core
• The lithosphere is said to be in constant but very slow motion. This movement of the lithosphere is called tectonics
• The Ring of Fire is one of the most geologically active areas on Earth and a site for frequent earthquakes and powerful volcanic eruptions
• Earthquakes on land can be caused either by tectonic plates movement or volcanic eruptions. Earthquakes under the sea can cause a tsunami
• The Philippines is at risk of disasters related to geologic activities like earthquakes, landslides, volcanic eruptions, and tsunamis
• There are regions where all four risks (earthquakes, landslides, volcanic eruptions, tsunamis) are highly present
• Batanes is the safest place in the country due to its very low risk in geologic disasters
• People should refrain from building high rise houses in Agusan Del Norte, Benguet, Camiguin, Davao
• The worst and irreversible effect of negligence or failure to prepare for natural geologic disasters is death
• The crust and a part of the upper mantle make up the lithosphere
• Plates are large pieces of the upper few hundred kilometers of Earth that move as a single unit as it moves above the mantle
• There are two kinds of crust: Continental plates which is thicker but less dense, and Oceanic plates which are thinner but denser
• Plate Tectonics is a theory which suggests that Earth's crust is made up of plates that constantly move and interact in various ways, thus, producing earthquakes, mountains, volcanoes, and other geologic features
• The plate that pushes the Philippine Plate towards the Eurasian plate is the Pacific Plate
• The world's earthquakes, volcanoes, and mountain ranges are situated at the same location near the edges of the continents
• Geologic activities such as seismicity or the occurrence of earthquake, volcanism, and mountain formations are the basis of scientists in dividing Earth's lithosphere
• Mountain ranges are found only in places where earthquake epicenters are situated
• A chemical reaction occurs when two substances combine chemically to produce new substances with different properties.
• A planet is an astronomical body that orbits around a star, such as Earth.
• Energy cannot be created or destroyed, only transferred from one form to another.
• The sun is the largest object in our solar system
• The sun is the source of all energy on earth
• Venus is known as Earth's twin because it is similar in size and mass but much hotter than Earth.
• Mars is also called the Red Planet due to its reddish appearance caused by iron oxide on its surface.
• Jupiter is the largest planet with a diameter larger than all other planets combined.
• Combination reactions involve combining elements or compounds to form one or more products.
• The three types of chemical reactions are combination, decomposition, and displacement.
• Earth's atmosphere consists mainly of nitrogen (78%) and oxygen (21%).
• The sun is a large ball of hot gas at the center of our solar system.
• Decomposition reactions break down larger molecules into smaller ones.
• Decomposition reactions break down larger molecules into smaller ones.
• An atom consists of protons, neutrons, and electrons.
• The three states of matter are solid, liquid, and gas.
• Matter can exist in three forms: solids, liquids, and gases.
• Mars is also called the "red planet" due to its reddish appearance caused by iron oxide on its surface.
