Restless Earth exam style starters.

1. 3 physical features which form as a result of fold mountain ranges:
- Valleys - U-shaped caused by glaciers traveling through it, wide valley floor
- Slopes - high and steep, upper slope - snow and rocks underneath, lower slope - grass, tree-line and alpine meadows.
- Snow - because of the high altitude(more on the mountain peaks)

2. Explain the formation of a U-shaped valley:
- U-shaped valleys are caused by glaciers. Glaciers are like a big tube of ice. But the valley is first shaped like a V-shape but that is when the river flows through it(light). So the glacier moves along the valley creating a U shape when friction happens on the sides and the bottom of the glacier making it move, there has to be a huge amount of ice to produce the friction, so it mainly depends on the weight of the ice. The movement comes mainly from the middle of the glacier. It scrapes the sides and floor of the river valley and when the ice melts the valley is greatly deepened, widened and is "U" shaped.

Skill Check on Fold Mountains

Why take notes? :
- Identify important concepts.
- good for revision.
- Build up understanding for a certain topic.
- So that we don't miss out of forget vital information when creating the pieces of work

What makes "good" notes? :
- Reliable sources (educational websites, compare resources and so that we're not gathering inaccurate information)
- Relevant information
- Key words and points
- Notes that are straight to the point (short or detailed)

Techniques we can use :
- Flashcards
- Presentations
- Bullet point on word
- Voice recording
- Mindmaps
- Fish-bone diagram
- Write and compare notes with a friend

Questions based on plate boundaries.

What are the differences between:-

a) Plates made of oceanic and continental crust?
- Oceanic plates are thin, while continental plates are thick.

b) Destructive and constructive margins?
- Destructive margins are when the dense oceanic crust is subducted under the less dense continental crust, while constructive plate margins are when two tectonic plates are moving away from each other. So, divergent and constructive margins move in the opposite direction.

c) How is a conservative margin different from those two?
- It is different because conservative margins aren't moving away or towards each other, instead its sliding past each other which causes earthquakes.

Plate Boundaries

Plate Boundaries

• is where plates meet and these plate boundaries are of 3 types convergent, divergent, conservative
• They have tectonic activities and are unstable.
• Found on the edge of the lithospheric plates

What do I notice? :-

• The northern american plate is the biggest
• The juan de fuca pleate is the smallest
• They don’t move in the same direction
• Lots of subducting plates - ocean and continental plates collide
• Different plates are in different continents and are named after them
• Some plates consist of trenches
• Some plates have ridges

Plate boundary map:-

Key - red lines are where the plates meet.

Key words:-

lithosphere - The solid outer part of the earth.

convergent - come together(destructive)

divergent - opposite of convergent(constructive)

conservative - transform

Locating Boundaries...


Name a place on earth where 2 plates are converging...
- Mount Everest, the tallest peak in the world.


Name a place where 2 plates are diverging...
- The Mid-Atlantic ridge and on land Lake Baikal in Siberia.


Name a place where 2 plates are sliding against each other...
- The San Andreas fault in North America.

Why is the Earth like a bowl of Trifle?

What is Geography?

Geography - The human activities including the distribution of population, resources and the study of physical of the earth and it's atmosphere.

Physical Geography - The natural features that already exist on the earths atmosphere, including climate, currents and the distribution of flora and fauna.

Human Geography - The human use, the understanding of the world and the processes which have affected it, including cities,
