Earth Layers
All of the water on Earth.
Hydrosphere.
The type of rock formed when magma cools down.
Igneous.
What are 3 natural disasters that transform landscapes?
Breaking down and movement of materials caused by external factors.
Weathering.
What is the hardest mineral in the world?
Diamond has a Mohs'10 on the scale.
The solid, outer layer of the Earth formed by the crust and part of the mantle.
Lithosphere.
The type of rock formed when different layers of materials are compacted.
Sedimentary.
When magma releases into the surface, it is called :
Lava
What is Erosion?
The movement of weathered material.
What is the mohs' scale ?
The scale to determine the hardness of a mineral, 1-10.
The collection of the Earth’s different layers.
Geosphere.
The type of rock that results from transforming an existing rock.
Metamorphic.
How do earthquakes occur?
When tectonic plates make sudden movements.
The 3 processes that create new forms in landscapes:
Deposition, Erosion, Weathering
Explain why there are many earthquakes in Japan:
Japan is situated near the meeting of two tectonic plates. Where two plates join there will be more movement which causes earthquakes.
The layer of gases that surrounds the Earth.
Atmosphere.
We classify rocks according to :
composition, texture, and where they appear in nature.
In which ocean are tsunamis most likely to occur ?
Pacific Ocean
What causes erosion?
Natural elements and forces.
Name the 4 ways humans use minerals :
The sections into which the Earth’s crust is divided.
Tectonic Plates.
Name the 5 properties of minerals :
Shape, Lustre, Colour/Streak, Hardness, Density
Tectonic plate movement can :
- ________ land and ________ land
Create Land & Destroy Land
Which element has got the biggest impact on changes (erosion)? and give 3 examples -
Water : rivers, oceans, rainfall, glaciers, groundwater.
What are the 4 natural elements/forces that cause changes in landscapes?
water, wind, gravity, living beings
