1 CHANGES WITHIN THE EARTHS SURFACE CHANGES WITHIN THE EARTHS SURFACE

2 The Earths Layers / 1. Core - center / Inner - solid/ outer-liquid 2. Mantle thick layer of rock 3. Crust rocky surface area

3 Land, Air and Water / Lithosphere --surface material (soil, rock, and other landforms ) / Atmosphere -- substances above the surface (air and water) / Biosphere -- plants, animals, and other living things / Continents -- 7 separate / Relief -- difference in elevation / Lithosphere --surface material (soil, rock, and other landforms ) / Atmosphere -- substances above the surface (air and water) / Biosphere -- plants, animals, and other living things / Continents -- 7 separate / Relief -- difference in elevation

4 Plate Tectonics / Movement and shifting of the plates / THERE ARE 4 TYPES OF PLATE MOVEMENT

5 4 Types of Movement / Subduction -- heavier plate slides down toward the mantle / Sea - Floor Spreading -- Magma comes from underneath and moves it away / Converging -- collide and create Mt. / Faulting -- plates slip or grind past each other / Subduction -- heavier plate slides down toward the mantle / Sea - Floor Spreading -- Magma comes from underneath and moves it away / Converging -- collide and create Mt. / Faulting -- plates slip or grind past each other

6 Changes on the Surface - sect. 3 / Weathering - break down at or near the Earths surface / 1. Mechanical -- rock is actually broken or weakened physically / Example--frost wedging / 2. Chemical -- Alters rocks chemical make up / a. Carbonic Acid -- dissolves rock / b. Acid rain -- chemicals combine with water / Weathering - break down at or near the Earths surface / 1.

7 EROSION / Movement of weathered materials including gravel, soil, and sand / Agents -- water, wind and glaciers / Movement of weathered materials including gravel, soil, and sand / Agents -- water, wind and glaciers

8 Water / Carries sediment away and this will grind away at the rock / Flood plain -- forms on the sides of rivers / Delta -- flat, low-lying plain formed at the mouth of the river, where the river enters the lake / Carries sediment away and this will grind away at the rock / Flood plain -- forms on the sides of rivers / Delta -- flat, low-lying plain formed at the mouth of the river, where the river enters the lake

9 Glaciers / Huge slow moving sheets of ice / 4 ice ages / Moraines -- piles of rock and debris left by glaciers / Huge slow moving sheets of ice / 4 ice ages / Moraines -- piles of rock and debris left by glaciers
