Learn

Sue Venir is on her summer holidays in Scotland, and it's raining!

Watch this animation (on the BBC websitehttps://www.bbc.co.uk/bitesize/articles/z4xdqp3 to

find out about the weather and climate in the UK and around the world.

What is weather?

Weather is a description of what the conditions are like in a particular place. For example, it could be:

hot or cold wet or dry windy or calm stormy, with thunder and lightning

websitehttps://www.bbc.co.uk/bitesize/articles/z4xdqp3 using these slides

What is climate?

Climate is a description of the average weather conditions in a certain place for

the past 30 or so years.

Different areas of the world have different climates.

Climate is influenced by lots of different things, including:

how near or far it is from the Equator

how near or far it is from the sea

how high or low the ground is

its position on a continent

Climate zones

There are several different climate zones around the world. These are large areas

that have similar climates.

Dahl class geography lessons 2

In the UK, we have a temperate climate which means we have four distinct seasons

with cool winters and warm summers. Other climate zones are very different to

ours.

out more.

Climate change

The climate across the world has changed naturally over thousands and

millions of years. In the past, the UK has experienced both freezing ice

ages and warm tropical climates.

Today however, more carbon dioxide has entered the Earth’s atmosphere,

this is for a number of reasons including the burning of fossil fuels to power

homes, factories and vehicles, the cutting down of trees (which normally absorb

carbon dioxide), the release of methane from landfill tips and the release of

nitrogen oxide and methane through certain types of farming.

Carbon dioxide acts like a greenhouse.

It lets the sun’s rays through to heat up everything inside the

atmosphere, but stops the heat from escaping.

This is making our planet warm faster than it naturally would and is

causing world climates to change.

Lesson 2

Biomes

Today we are using this BBC Bitesize web page https://www.bbc.co.uk/bitesize/articles/zbnc86f

Learn

What are biomes?

Biomes are areas of our planet with

similar climates, landscapes, animals and plants. What lives in each biome depends

on:

how warm or cold it is

how dry or wet it is

how fertile the soil is

The animals in a biome depend upon plants for food. The plants in a biome often

also depend upon the animals for spreading pollen and seeds so that new plants can

grow. So both plants and animals rely on each other to stay alive.

Watch this short animation with Sue Venir to find out more.

Types of biome

Tropical rainforests are hot and wet all year round. They are home to half of

all the different types of plants and animals on the planet.

Deserts are hot and dry all year round. The only things that grow are cacti and

small shrubs because the soil is shallow and rocky. Animals come out at dusk

when it is cooler.

The savannah is hot all year round with a long dry season. Only grasses and

shrubs grow here but it is home to lots of different types of animals such as elephants, zebras and wildebeest.

Woodlands are habitats where the main plants found are trees; but mosses, ferns and lichen can also be found. The

climate is warm and mild, with more rain falling in the winter than the summer.

Dahl class geography lessons 2

Grasslands are areas of land that are vast and open, with grasses being the main plants. The largest grasslands are

found in East Africa. Zebras, giraffes, elephants and rhinos can all be found living in grasslands.

The tundra is the coldest of all the biomes. There is very little rain or snow and the temperatures are freezing.

Winters are long and summers are short. Part of the soil is frozen all year round, although the top part defrosts in

summer and plants such as mosses can grow.

Lesson 3

Rivers

Using the website https://www.bbc.co.uk/bitesize/topics/z849q6f/articles/z7w8pg8

Watch

What is a river?

A river is a moving body of water that flows from its source on high ground,

across land, and then into another body of water, which could be a lake,

the sea, an ocean or even another river.

A river flows along a channel with banks on both sides and a bed at the bottom.

If there is lots of rainfall, or snow or ice melting, rivers often rise over the top

of their banks and begin to flow onto the floodplains at either side.

How are rivers formed?

Rivers usually begin in upland areas, when rain falls on high ground and begins to

flow downhill. They always flow downhill because of gravity.

They then flow across the land - meandering - or going around objects such as

hills or large rocks. They flow until they reach another body of water.

As rivers flow, they erode - or wear away - the land. Over a long period of time

rivers create valleys, or gorges and canyons if the river is strong enough to

erode rock. They take the sediment - bits of soil and rock - and carry it along

with them.

Small rivers are usually known as streams, brooks or creeks. If they flow from

underground they are called springs.

Lessons 4 and 5

The Lake District.

Using the website https://www.bbc.co.uk/bitesize/topics/z3fycdm/articles/zvys8xs

Watch

Where is the Lake District?

The Lake District is a national park and World Heritage Site in North West

England. It is home to the highest mountain in England - Scafell Pike, and the

deepest lake - Wastwater. It is popular with both day visitors and

holidaymakers because of its beautiful mountains and lakes.

What is it like in the Lake District?

The landscapes of the Lake District have been created over millions and

millions of years. Rocks such as sandstone, limestone and granite gradually

formed in layers. Next, tectonic plates created volcanoes and also pushed the

rock up to create high mountains.

Two million years ago, icy glaciers covered the mountains and as the glaciers

slowly crept down the mountains, they picked up pieces of rock, which eroded

the mountains and created valleys. When the ice melted, these valleys filled up

with the melted water and created deep lakes. Small crevices made by the ice

at the tops of mountains filled with water to create tarns.

The Lake District is home to lots of plants and animals and also people, who live

in towns such as Keswick and Windermere. Tourism is an

important industry here, with over 12 million visitors every year who come to

walk, cycle, run, boat or just to look at the amazing scenery.
