Changing landforms
How do weathering and erosion work together to shape landforms?
Weathering breaks down rocks into smaller pieces, while erosion transports those pieces to new locations. Together the shape mountains, valleys, and other landforms over time.
What are sedimentary rocks made of?
Sedimentary rocks are made up from particles from other rocks, minerals, and organic material that have been compacted and cemented together.
What are fossil fuels?
Fossil fuels are natural resources formed from the remains of ancient plants and animals that have been buried and changed over MILLIONS of years.
What are the main stages of the water cycle?
Evaporation, condensation, precipitation, and collection.
What are physical properties?
Physical properties are characteristics of a substance that can be observed or measured without changing the substance itself.
What is a delta, and how is it formed? Why are deltas important for the environment?
A delta is formed when a river slows and deposits sediment at its mouth. Deltas are important because they create fertile land and provide habitats for many species.
Can you name the three main types of rocks, and where sedimentary rocks fit in?
Igneous, metamorphic, and sedimentary. Sedimentary rocks form from the accumulation of sediment , unlike igneous rocks, which form from cooled magma, and metamorphic rocks, which are altered by heat and pressure.
Can you name three types of fossil fuels?
The three main types of fossil fuels are coal, oil, and natural gas.
What happens during evaporation?
During evaporation, water from oceans, rivers, and lakes turns into vapor and rises into the atmosphere due to heat from the sun.
Can physical properties change? if so, give an example.
Yes, physical properties can change. For example, water can change from liquid to ice (solid) when it freezes, altering its shape and volume.
How can glaciers change landforms, and what features do they leave behind?
Glaciers erode land as they move, creating valleys and fjords. They leave behind features like moraines, kettles, and drumlins.
What role do water and wind play in the formation of sedimentary rocks?
Water and wind can erode rocks, transporting sediments to new locations. This material can settle in layers, which eventually become compacted into sedimentary rocks.
What are some examples of Nonrenewable resources and some examples of renewable resources?
What forms can precipitation take?
Precipitation can occur as rain, snow, sleet, or hail, depending on the temperature and conditions in the atmosphere.
What are some physical properties?
Color, size, shape, texture, mass, volume, density, state of matter, boiling point, melting point.
What Landforms can happen quickly?
Landslides, earthquakes, and volcanoes.
What are fossils, and why are they often found in sedimentary rocks?
Fossils are the remains of plants and animals that have been preserved. they are often found in sedimentary rocks because these rocks form in environments where organisms can be buried, such as riverbeds, lakes, and ocean floors.
What is coal used for?
Coal is primarily used for generating electricity and heating, and it can also be used in industries to produce steel.
Can you explain what condensation is?
Condensation is the process where water vapor cools and changes back into liquid water, forming clouds.
Color is a physical property because it helps identify a substance without changing it. For example, we can observe that a leaf is green without changing what the leaf is.
How can human activities impact landforms? Can you think of any examples?
Human activities like mining, construction, and deforestation can alter landforms. For example, building roads can change the natural flow of water and lead to erosion.
What is the sedimentary rock cycle? what does each one mean?
Weathering is a natural process that breaks apart rocks through wind, rain, ice and other natural processes. Erosion is where sediment moved from one place to another. Deposition is where sediment is dropped off/added to a landform or landmass. Compaction is where sediment is squeezed, squished, and smashed down into layers. Cementation is where layers of sediment are exposed to water and other materials and get stuck and glued together.
What are some disadvantages of using fossil fuels?
Burning fossil fuels releases pollution and greenhouse gases, which can harm the environment and contribute to climate change.
Can you explain the water cycle in your own words?
(answer related to water cycle)
A graduated cylinder or measuring cup ca be used to measure the volume of a liquid. Understanding volume is an important physical property because it tells us how much space a liquid occupies.
