Weathering
Earth's surface today is different from what it was in the past and what it will be in the future due to -
What is weathering
This form of weathering will break a rock apart, increasing its surface area. Smaller rocks, sand, and clay can result from this weathering..
The process of changing once-living material into dark-colored organic matter.
What is decomposition?
Changes the materials that are part of a rock into new material
What is Chemical Weathering
Rocks that are formed from pieces of other existing rocks or organic material.
Sedimentary Rocks
Over thousands of years, weathering can break rock into smaller and smaller pieces that are also known as
What is sediments
One of the most effective weathering processes.
What is Ice Weathering
Materials that have never been alive
What is inorganic?
Increases the rate of chemical weathering more than water does
What are acids?
Are the three types of rocks in the rock cycle
Sedimentary rocks, igneous rocks, metamorphic rocks
Soil pieces are sand which are larger than the smaller soil pieces..
What is clay?
A weathering process where grinding away of rock by friction or impact occurs.
What is abrasion?
The remains of something that was once alive
What is organic matter?
Is a property of solutions to learn if a solution is acid
What is the PH of water?
how the three rock types are related to each other, and how processes change from one type to another over time.
The rock cycle
Often these changes can make a rock easier to break down.
What is chemical changes
More water sticks to clay based on this.
What is surface area?
Small holes and spaces that allow water to flow
What are pores?
When oxygen atoms combine with atoms of other elements or moleculues
What is oxidation?
The rocks and the soil around us are the products of millions of years of transformation due to a variety of different geological processes.
Weathering causes rocks to break down into sediment, such as sand, silt, and clay, which make this up.
Combines the element oxygen with other elements or molecules
What is oxidation
Is made up of rock fragments, water, and air
What is soil?
Increases the rate of chemical reaction.
The cooling and solidification of magma that happens over time creates
What is igneous rocks?
