Natural features found on Earth, including g mountains, valleys, lakes, canyons, etc...
What are LANDFORMS?
The Earth's crust is broken into several huge pieces of rock. These are called __________. They move at the same speed as your fingernails grow.
What are PLATES?
________________ is when there hasn't been any rain for a long period of time and the ground is dry and cracked.
What is DROUGHT?
Too much rain, rising rivers, storm surges can all cause _________________.
What are FLOODS?
Thick sheets of ice that move slowly and shape the land by carving it out and depositing eroded rock elsewhere are called ________________. They created valleys and canyons, like the Grand Canyon.
What are GLACIERS?
The Earth' s thin outermost layer; we live on it.
What is the CRUST?
Plates move at cracks in the Earth's crust and can cause lots of damage. These cracks in the Earth's crust are called _____________.
What are FAULTS?
What are some ways a wildfire can start?
(at least 2)
1. Dry/drought like conditions
2. Litter like glass bottles magnify sun's rays
3. Careless humans - matches / campfires / cigarettes
4. Lightning strike
The very center of a hurricane is called the _________________. It is the calmest part of the hurricane.
What is the EYE of the hurricane?
______________ is the slow process of breaking down rocks into smaller pieces. It can be caused by plants, flowing water, and wind.
What is WEATHERING?
The layer of rock below the crust. It is solid, but can move or change shape at high temperatures and pressure.
What is the MANTLE?
Movement of plates at faults causes pushing together, folding under. moving up, down, and side to side. Landforms such as _________________ and _________________ can be created at these points.
What are MOUNTAINS and VOLCANOES?
The very center of the earthquake is called the ____________________.
What is the EPICENTER?
A___________ is a giant, destructive ocean wave that can be caused by an _________________ under or near to the water.
What is a TSUNAMI?
What is an EARTHQUAKE?
______________ is the actual removal / moving of broken rock pieces. It can be caused by flowing water, gravity, wind, and glaciers.
Once the weathered rock is moved, it is then 'dropped off' somewhere else reshaping the land further. This 'dropping off' is called ____________. For example, sand being blown by the wind then dropped off elsewhere creates sand dunes.
What is EROSION?
What is DEPOSITION?
Below the mantle lies the __________________. This is the liquid layer made mostly of melted iron.
What is the OUTER CORE?
Many of Earth's earthquakes and volcanoes are found in a specific area in the Pacific Ocean. It has a nickname: The "__________________".
What is The Ring of Fire?
An active volcano can __________.
The molten rock that is spit out of the volcano is called ____________.
The molten rock that is still below the Earth's crust is called _____________.
What is ERUPT?
What is LAVA?
What is MAGMA?
Compare & contrast landslides and avalanches.
(Similarities & Differences.)
They are both caused by which force?
1. They are both a type of landslide - the sudden downhill movement of Earth's materials
2. Landslides include soil, rocks, and mud
3. Avalanches include snow and ice
What is GRAVITY?
List at least 2 NEGATIVE ways that people shape the land:
1.
2.
1. Mining - digging into the land
2. Landfills - dumps - piles of trash - pollution
3. Forests - deforestation
The center of the Earth is called the ______________________. It is a sphere of solid material probably made of ________________. It is the hottest part of the Earth.
What is the INNER CORE?
What is IRON?
The name of what scientists believe was once the Earth's one Super Continent?
What is PANGAEA?
The ________ _________ of earthquakes are measured by scientists using this tool:____________________.
What are SEISMIC WAVES?
What is a SEISMOGRAPH?
Compare & contrast hurricanes and tornadoes.
(Similarities & differences.)
1. Size - Hurricanes larger(wider path) / Tornadoes smaller(narrow path)
2. Type - Tornadoes are spinning columns of wind born from a storm / Hurricanes are spinning storms
3. Speed - Tornadoes can reach faster wind speeds
4. Damage - both can be very destructive
5. Length of time - Hurricanes last longer
Explain the difference between physical weathering & chemical weathering.
Give an example of how each type is caused.
Physical Weathering - rocks change size and shape WITHOUT CHANGING their chemical makeup.
Examples - plant roots, moving water, freezing and thawing water, rain, wind, etc..
Chemical Weathering - the chemical makeup/minerals of the rocks ARE CHANGED.
Examples - oxygen, carbon dioxide, acid rain, rust, etc...
