Defining Characteristics of the Plant Kingdom: Multicellular Terrestrial Embryophytes Photosynthetic (almost all) Eukaryotic 4 Major Groups 1. Non-Vascular Plants (Bryophytes and Friends) No vascular tissue – therefore must rely on surrounding moisture and osmosis to move fluids through their bodies. Small in stature, and simplistic – NO organs (roots, leaves, stems) (Rhizoids = root-like structures…
One of the most obvious signs of prosperity in the 1920s was the growth of the automobile industry. Henry Ford dreamed of making an inexpensive car that almost anyone could afford to buy. Ford decided to apply to car manufacturing a method of mass production that was being used in some industries. Ford set up…
What is Ozone?-Ozone is a gas made up of three oxygen atoms (O3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). O + O3 → 2 O2 Chlorofluorocarbons and ozone Many people have heard that chemicals called CFCs, short for chlorofluorocarbons, cause the ozone hole. CFCs escape into the atmosphere…
Plants Theory (recent): Given by University research team Global cooling was caused by reduction of carbon in the atmosphere due to the first appearance of plants (photosynthesis) Less greenhouse gas (carbon) to prevent escape of infrared radiation which leads to cooler temperatures (less heat trapped) Plants (ex. moss) extract calcium, magnesium, phosphorus and iron which…
The volcanic ash cloud created by a volcanic blast can change interactions between the atmosphere and sun, affecting climate patterns. When a volcano erupts, the main things that come out of it are sulfur dioxide, water vapor, dust and ash that go in the atmosphere. The eruption of a volcano can cause a cooling or…

World’s coldest and driest biomes Located at latitudes 55° to 70° North( circumnavigating the North pole) 3 types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra vast and treeless land which covers about 20% of the Earth’s surface cold, and the land is pretty stark low growing plants like mosses, heaths,…
La Nina Pacific temperature cooler than normal Last 9-12 months Pacific Ocean drops 3-5 degrees Reoccurs every 3-7 years Cause by a decrease of ocean temp and increase in trade wind strength Westward wind gets stronger Allowing low cooler water to surface toward South America Cloud build up in Southeast Asia Wet period in middle…
The process of the ocean water on Earth circulating due to heat and salinity. Thermo stands for heat, haline stands for salt. The less dense warm water flows over the more dense cool water This current is vulnerable to rising temperatures The salinity of the ocean water is decreasing near the poles due to the…
The IPCC is known as the Intergovernmental Panel on Climate Change and was established in 1988 by the UNEP (United Nations Environment Programme) and the WMO (World Meteorological Organization). It is one of the leading panels on the assessment of climate change. They provide scientific assessments about the risk of climate change. ROLES OF IPCC:…
What is Happening? The Greenland ice sheet is melting. The ice sheet melting will result in less saline (less dense) water entering the North Atlantic Ocean and floating on top of it instead of sinking, causing less and less deep water currents to moderate the globe’s climate, especially Northern Europe’s. Deep water currents are mainly…
Run-on sentences occur when independent clauses are not joined properly. There are two types of run-on sentence: the fused sentence and the comma splice. ►Fused sentences occur when there is no punctuation and no coordinating conjunction between two independent clauses. The snow needs to be shovelled get going on it right away. ►Comma splices occur…

By selecting the right hand tool of the correct size a technician should be able to perform almost any task that is required. Hand…
Mass: mass is the amount of material in an object. Mass is measured with a balance, usually in grams or kilograms. Volume: volume is the amount of space occupied by an object. Volume is measured using a graduated cylinder or is determined by calculation using the dimensions of the object. Volume is measured in cm3, m3, mL…
