Adverbs modify verbs, adjectives and other adverbs, for example runningquickly, veryclever, quitewell.

Adverbs of manner describe how the action of the verb is being done, for example boldly, graciously, well.

Adverbs of time show when the action of the verb is taking place, for example today, then.

Adverbs of place show where the action of the verb is taking place, for example here.

Question 1

Draw a line of symmetry on each of the shapes below.

Look at the shapes below. The symmetry of the shape on the left and its relationship to the shape on the right can be thought of in two ways:

• Fold the left-hand shape along the central line. Then one side lies exactly on top of the other, and gives the shape on the right.

• Imagine a mirror placed along the central dotted line. The reflection in the mirror gives the other half of the shape.

Generic Representations and the Generic Grid: Knowledge Interface, Organisation and Support of the (
Computer Aided Design requires the implementation of architectural issues in order to support the architectural design process. These issues consist of elements, knowledge structures, and design processes that are typical for architectural design. The paper introduces two concepts that aim to define and model some of such architectural issues: building types and design processes. The first concept, the Generic grid, will be shown to structure the description of designs, provide a form-based hier

Having made and reviewed our observations, we are now in a position to interpret them â€“ why are the rocks the way they are? The sedimentary strata that we see in Figure 16 were likely to have been deposited in essentially horizontal layers, so why is one set tilted and the other horizontal? To answe

We now want to make use of the observations obtained by sketching the exposure, and it is useful to start by briefly summarising the features seen. First of all, you probably noticed the large boulder in the foreground of Figure 16 (which has been attached below for ease of access). Where did this bou

Activity 5

What natural process could cause a rock to be heated?

Heating can be caused when hot magma is intruded into a cool rock.
Author(s): The Open University

Any type of rock can become a metamorphic rock if it is heated to temperatures of several hundred degrees Celsius, and/or if subjected to high pressure (because of the weight of overlying rocks). During metamorphism, the minerals making up the rock become chemically unstable, meaning that their constituent ions are redistributed. The result is that either large crystals grow at the expense of existing smaller ones, or a new set of minerals is formed. Generally speaking, the overall chemical c

Consider some of the places where sedimentary materials are moved and deposited. Are the sediments always laid down in perfectly horizontal, perfectly flat layers? No; as often as not, the depositing surface is not perfectly flat. Instead, a system of parallel ridges, or ripple marks, like the ones shown in Figure 13a, form by the action that flowing water has on the erosion, transport and deposition of sand grains. In sedimentary strata, ripples and dunes (which are effectively larger versio

We've seen that the detective work of piecing together a part of Earth's history from sedimentary rocks involves detailed investigation of rock samples, but this can give only a partial picture. On the larger scale of a rock exposure, there can be plenty for us to see and to interpret. Sedimentary rocks are usually found as layers referred to as strata (Figure 10), with each stratum (layer) recording the particular conditions at the time of its deposition. (Note: sedimentary layers are often
Author(s): The Open University

Sedimentary grains are formed when the rocks at the Earth's surface are slowly broken up physically by exposure to wind and frost, and decomposed (chemically) by rainwater or biological action. These processes are collectively termed weathering. Once a rock has been broken up by weathering, the small rock fragments and individual mineral grains can be eroded from their place of origin by water, wind or glaciers and transported to be deposited elsewhere as roughly horizontal layers of sediment
Author(s): The Open University

The laying down, or deposition, of layers of rock fragments, mineral grains, or biological material, such as the shells or other hard parts of dead organisms, can produce sedimentary rocks. Once deposited, the loose, unconsolidated sediment may be converted into a solid rock by compaction and cementing of the grains together by chemical action deep below the surface. These rocks consist, therefore, of fragments of sedimentary material, bound together by even smaller fragments, or some sort of

As well as varying in grain size (owing to different cooling rates), igneous rocks also vary in chemical composition and hence in the identity and proportions of minerals present. For instance, the common igneous rock granite contains (as part of the strict geological definition of the term â€˜graniteâ€™) between 10% and 35% by volume of the mineral quartz (chemical composition silicon dioxide â€“ SiO2). On the other hand, the igneous rock gabbro (Figure 4a) does not
